-## [1.4.0] - 2021-03-11
-* **Metrics**: Ability to set default dimension for metrics via `MetricsUtils.defaultDimensionSet()`.
-
- **Note**: If your monitoring depends on [default dimensions](https://github.com/awslabs/aws-embedded-metrics-java/blob/master/src/main/java/software/amazon/cloudwatchlogs/emf/logger/MetricsLogger.java#L173) captured before via [aws-embedded-metrics-java](https://github.com/awslabs/aws-embedded-metrics-java),
- those either need to be updated or has to be explicitly captured via `MetricsUtils.defaultDimensionSet()`.
-
+## Pull Requests
-* **Metrics**: Remove validation of having minimum one dimension. EMF now support [Dimension set being empty](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format_Specification.html) as well.
+* Merge pull request [#1](https://github.com/aws-powertools/powertools-lambda-java/issues/1) from stevehouel/master
-## [1.3.0] - 2021-03-05
-* **Powertools**: It now works out of the box with [code guru profile handler implementation](https://docs.aws.amazon.com/codeguru/latest/profiler-ug/lambda-custom.html).
-* **Logging**: Ability to override object mapper used for logging event. This provides customers ability to customize how and what they want to log from event.
-* **Metrics**: Module now by default captures AWS Request id as property if used together with Metrics annotation. It will also capture Xray Trace ID as property if tracing is enabled. This ensures good observability and tracing.
-* **Metrics**:`withSingleMetric` from `MetricsUtils can now pick the default namespace specified either on Metrics annotation or via POWERTOOLS_METRICS_NAMESPACE env var, without need to specify explicitly for each call.
-* **Metrics**:`Metrics` annotation captures metrics even in case of unhandled exception from Lambda function.
-* **Docs**: Migrated from Gatsby to MKdocs documentation system

## Contributing via Pull Requests
+
Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:
-1. You are working against the latest source on the *master* branch.
-2. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
-3. You open an issue to discuss any significant work - we would hate for your time to be wasted.
+1. You are working on a fork. [Fork the repository](https://github.com/aws-powertools/powertools-lambda-java/fork).
+2. You are working against the latest source on the **main** branch.
+3. You've checked existing open, and recently merged pull requests to make sure someone else hasn't addressed the problem already.
+4. You've opened an [issue](https://github.com/aws-powertools/powertools-lambda-java/issues/new/choose) before you begin any implementation. We value your time and bandwidth. As such, any pull requests created on non-triaged issues might not be successful.
+
+### Dev setup
+
+We recommend using [IntelliJ IDEA](https://www.jetbrains.com/idea/) from JetBrains.
+A community version is available and largely enough for our purpose.
+
+#### Code Formatting
+
+We strongly recommend installing the CheckStyle-IDEA plugin and apply the provided [checkstyle.xml](checkstyle.xml) in order to comply with our formatting rules:
+
+1. Install the [CheckStyle-IDEA plugin](https://plugins.jetbrains.com/plugin/1065-checkstyle-idea) and restart IntelliJ.
+
+2. After installing the plugin, open the preferences (`⌘,` on macOS, or `Ctrl+Alt+S` on Windows/Linux) and search for _Code Style_. Click on the gear icon near the scheme and import checkstyle configuration. Click on "Apply" and "OK".
+
+
+3. Select the code you've created (module, package, class) and reformat code: `⌘⌥L` (macOS), or `Ctrl+Alt+L` (Windows/Linux).
+
+4. Apply the reformat, optimize imports, rearrange and cleanup to your code and only to java files:
+
+
+#### License headers
+All the java files should contain the licence/copyright header. You can copy paste it from the [license-header](license-header) file.
-To send us a pull request, please:
+### Creating the pull request
-1. Fork the repository.
-2. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
-3. Ensure local tests pass.
-4. Commit to your fork using clear commit messages.
-5. Send us a pull request, answering any default questions in the pull request interface.
-6. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.
+To send us a pull request, please follow these steps:
+
+1. Create a new branch to focus on the specific change you are contributing e.g. `improv/logger-debug-sampling`
+2. Run all tests, and code baseline checks: `mvn clean verify -P build-with-spotbugs`
+3. Commit to your fork using clear commit messages.
+4. Send us a pull request with a [conventional semantic title](.github/semantic.yml), and answering any default questions in the pull request interface.
+5. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.
GitHub provides additional document on [forking a repository](https://help.github.com/articles/fork-a-repo/) and
[creating a pull request](https://help.github.com/articles/creating-a-pull-request/).
+### Local documentation
+
+If you work on the documentation, you may find useful to display it locally while editing, using the following command:
+
+- **Docs website**: `make docs-local-docker`
+
+## Conventions
+
+### General terminology and practices
+
+| Category | Convention |
+|-----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| **Style guide** | We use Checkstyle and Sonar to enforce beyond good practices. |
+| **Exceptions** | Specific exceptions live within the utilities themselves and use `Exception` suffix e.g. `IdempotencyKeyException`. |
+| **Git commits** | We follow [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/). We do not enforce conventional commits on contributors to lower the entry bar. Instead, we enforce a conventional PR title so our label automation and changelog are generated correctly. |
+| **API documentation** | API reference docs are generated from Javadoc which should have examples to allow developers to have what they need within their own IDE. Documentation website covers the wider usage, tips, and strive to be concise. |
+| **Documentation** | We treat it like a product. We sub-divide content aimed at getting started (80% of customers) vs advanced usage (20%). We also ensure customers know how to unit test their code when using our features. |
+
+### Testing definition
+
+We group tests in different categories
+
+| Test | When to write | Notes | Speed |
+| ----------------- | ----------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------- |
+| Unit tests | Verify the smallest possible unit works. | Networking access is prohibited. Prefer Functional tests given our complexity. | Lightning fast (nsec to ms) |
+| End-to-end tests | Gain confidence that a Lambda function with our code operates as expected. | It simulates how customers configure, deploy, and run their Lambda function - Event Source configuration, IAM permissions, etc. | Slow (minutes) |
+
+**NOTE**: Unit tests are mandatory. End-to-end tests should be created for new modules.
+We apply the principle of the [test pyramid](https://martinfowler.com/articles/practical-test-pyramid.html), having a majority of unit tests to cover most cases (standard, edge, errors, ...) and generally one end-to-end test to verify the standard case in the target environment.
## Finding contributions to work on
-Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any 'help wanted' issues is a great place to start.

+# GraalVM Compatibility for AWS Lambda Powertools Java
+
+## Table of Contents
+- [Overview](#overview)
+- [Prerequisites](#prerequisites)
+- [General Implementation Steps](#general-implementation-steps)
+- [Known Issues and Solutions](#known-issues-and-solutions)
+- [Reference Implementation](#reference-implementation)
+
+## Overview
+This documentation provides guidance for adding GraalVM support for AWS Lambda Powertools Java modules and using the modules in Lambda functions.
+
+## Prerequisites
+- GraalVM 21+ installation
+- Maven 3.x
+
+## General Implementation Steps
+GraalVM native image compilation requires complete knowledge of an application's dynamic features at build time. The GraalVM reachability metadata (GRM) JSON files are essential because Java applications often use features that are determined at runtime, such as reflection, dynamic proxy classes, resource loading, and JNI (Java Native Interface). The metadata files tell GraalVM which classes need reflection access, which resources need to be included in the native image, and which proxy classes need to be generated.

+In order to generate the metadata reachability files for Powertools for Lambda, follow these general steps.
+
+1. **Add Maven Profiles**
+ - Add profile for generating GraalVM reachability metadata files. You can find an example of this in profile `generate-graalvm-files` of this [pom.xml](powertools-common/pom.xml).
+ - Add another profile for running the tests in the native image. You can find and example of this in profile `graalvm-native` of this [pom.xml](powertools-common/pom.xml).
+
+2. **Generate Reachability Metadata**
+ - Set the `JAVA_HOME` environment variable to use GraalVM
+ - Run tests with `-Pgenerate-graalvm-files` profile.
+```shell
+mvn -Pgenerate-graalvm-files clean test
+```
+
+3. **Validate Native Image Tests**
+ - Set the `JAVA_HOME` environment variable to use GraalVM
+ - Run tests with `-Pgraalvm-native` profile. This will build a GraalVM native image and run the JUnit tests.
+```shell
+mvn -Pgraalvm-native clean test
+```
+
+4. **Clean Up Metadata**
+ - GraalVM metadata reachability files generated in Step 2 contains references to the test scoped dependencies as well.
+ - Remove the references in generated metadata files for the following (and any other references to test scoped resources and classes):
+ - JUnit
+ - Mockito
+ - ByteBuddy
+
+## Known Issues and Solutions
+1. **Mockito Compatibility**
+ - Powertools uses Mockito 5.x which uses “inline mock maker” as the default. This mock maker does not play well with GraalVM. Mockito [recommends](https://github.com/mockito/mockito/releases/tag/v5.0.0) using subclass mock maker with GraalVM. Therefore `generate-graalvm-files` profile uses subclass mock maker instead of inline mock maker.
+ - Subclass mock maker does not support testing static methods. Tests have therefore been modified to use [JUnit Pioneer](https://junit-pioneer.org/docs/environment-variables/) to inject the environment variables in the scope of the test's execution.
+
+2. **Log4j Compatibility**
+ - Version 2.22.1 fails with this error
+```
+java.lang.InternalError: com.oracle.svm.core.jdk.UnsupportedFeatureError: Defining hidden classes at runtime is not supported.
+```
+ - This has been [fixed](https://github.com/apache/logging-log4j2/discussions/2364#discussioncomment-8950077) in Log4j 2.24.x. PT has been updated to use this version of Log4j
+
+3. **Test Class Organization**
+ - **Issue**: Anonymous inner classes and lambda expressions in Mockito matchers cause `NoSuchMethodError` in GraalVM native tests
+ - **Solution**:
+ - Extract static inner test classes to separate concrete classes in the same package as the class under test
+ - Replace lambda expressions in `ArgumentMatcher` with concrete implementations
+ - Use `mockito-subclass` dependency in GraalVM profiles
+ - **Example**: Replace `argThat(resp -> resp.getStatus() != expectedStatus)` with:
+ ```java
+ argThat(new ArgumentMatcher<Response>() {
+ @Override
+ public boolean matches(Response resp) {
+ return resp != null && resp.getStatus() != expectedStatus;
+ }
+ })
+ ```
+
+4. **Package Visibility Issues**
+ - **Issue**: Test handler classes cannot access package-private methods when placed in subpackages
+ - **Solution**: Place test handler classes in the same package as the class under test, not in subpackages like `handlers/`
+ - **Example**: Use `software.amazon.lambda.powertools.cloudformation` instead of `software.amazon.lambda.powertools.cloudformation.handlers`
+
+5. **Test Stubs Best Practice**
+ - **Best Practice**: Avoid mocking where possible and use concrete test stubs provided by `powertools-common` package
+ - **Solution**: Use `TestLambdaContext` and other test stubs from `powertools-common` test-jar instead of Mockito mocks
+ - **Implementation**: Add `powertools-common` test-jar dependency and replace `mock(Context.class)` with `new TestLambdaContext()`

+# Automatic Priming for AWS Lambda Powertools Java
+
+## Table of Contents
+- [Overview](#overview)
+- [Implementation Steps](#general-implementation-steps)
+- [Known Issues](#known-issues-and-solutions)
+- [Reference Implementation](#reference-implementation)
+
+## Overview
+Priming is the process of preloading dependencies and initializing resources during the INIT phase, rather than during the INVOKE phase to further optimize startup performance with SnapStart.
+This is required because Java frameworks that use dependency injection load classes into memory when these classes are explicitly invoked, which typically happens during Lambda’s INVOKE phase.
+
+This documentation provides guidance for automatic class priming in Powertools for AWS Lambda Java modules.
+
+
+## Implementation Steps
+Classes are proactively loaded using Java runtime hooks which are part of the open source [CRaC (Coordinated Restore at Checkpoint) project](https://openjdk.org/projects/crac/).
+Implementations across the project use the `beforeCheckpoint()` hook, to prime Snapstart-enabled Java functions via Class Priming.
+In order to generate the `classloaded.txt` file for a Java module in this project, follow these general steps.
+
+1. **Add Maven Profile**
+ - Add maven test profile with the following VM argument for generating classes loaded files.
+ ```shell
+ -Xlog:class+load=info:classesloaded.txt
+ ```
+ - You can find an example of this in `generate-classesloaded-file` profile in this [pom.xml](powertools-metrics/pom.xml).
+
+2. **Generate classes loaded file**
+ - Run tests with `-Pgenerate-classesloaded-file` profile.
+ ```shell
+ mvn -Pgenerate-classesloaded-file clean test
+ ```
+ - This will generate a file named `classesloaded.txt` in the target directory of the module.
+
+3. **Cleanup the file**
+ - The classes loaded file generated in Step 2 has the format
+ `[0.054s][info][class,load] java.lang.Object source: shared objects file`
+ but we are only interested in `java.lang.Object` - the fully qualified class name.
+ - To strip the lines to include only the fully qualified class name,
+ Use the following regex to replace with empty string.
+ - `^\[[\[\]0-9.a-z,]+ ` (to replace the left part)
+ - `( source: )[0-9a-z :/._$-]+` (to replace the right part)
+
+4. **Add file to resources**
+ - Move the cleaned-up file to the corresponding `src/main/resources` directory of the module. See [example](powertools-metrics/src/main/resources/classesloaded.txt).
+
+5. **Register and checkpoint**
+ - A class, usually the entry point of the module, should register the CRaC resource in the constructor. [Example](powertools-metrics/src/main/java/software/amazon/lambda/powertools/metrics/MetricsFactory.java)
+ - Note that AspectJ aspect is not suitable for this purpose, as it does not work with CRaC.
+ - Add the `beforeCheckpoint()` hook in the same class to invoke `ClassPreLoader.preloadClasses()`. The `ClassPreLoader` class is implemented in `powertools-common` module.
+ - This will ensure that the classes are already pre-loaded by the Snapstart RESTORE operation leading to a shorter INIT duration.
+
+
+## Known Issues
+- This is a manual process at the moment, but it can be automated in the future.
+- `classesloaded.txt` file includes test classes as well because the file is generated while running tests. This is not a problem because all the classes that are not found are ignored by `ClassPreLoader.preloadClasses()`. Also `beforeCheckpoint()` hook is not time-sensitive, it only runs once when a new Lambda version gets published.
+
+## Reference Implementation
+Working example is available in the [powertools-metrics](powertools-metrics/src/main/java/software/amazon/lambda/powertools/metrics/MetricsFactory.java).

+
+Many utilities use `aspectj-maven-plugin` to compile-time weave (CTW) aspects into the project. When using it with Kotlin projects, it is required to `forceAjcCompile`.
+No explicit configuration should be required for gradle projects.
+

+
+To enable `forceAjcCompile` you need to use following `aspectj-maven-plugin` configuration:

+
+## How can I use Powertools for AWS Lambda (Java) with the AWS CRT HTTP Client?
+
+Utilities relying on AWS SDK clients use the `url-connection-client` as the default HTTP client. The `url-connection-client` is a lightweight HTTP client, which keeps the impact on Lambda cold starts to a minimum.
+With the [announcement](https://aws.amazon.com/blogs/developer/announcing-availability-of-the-aws-crt-http-client-in-the-aws-sdk-for-java-2-x/) of the `aws-crt-client` a new HTTP client has been released, which offers faster SDK startup time and smaller memory footprint.
+
+Unfortunately, replacing the `url-connection-client` dependency with the `aws-crt-client` will not immediately improve the lambda cold start performance and memory footprint,
+as the default version of the dependency contains native system libraries for all supported runtimes and architectures (Linux, MacOS, Windows, AMD64, ARM64, etc). This makes the CRT client portable, without the user having to consider _where_ their code will run, but comes at the cost of JAR size.
+
+### Configuring dependencies
+
+Using the `aws-crt-client` in your project requires the exclusion of the `url-connection-client` transitive dependency from the `powertools-*` dependency.
+
+```xml
+<dependency>
+ <groupId>software.amazon.lambda</groupId>
+ <artifactId>powertools-parameters</artifactId>
+ <version>2.0.0</version>
+ <exclusions>
+ <exclusion>
+ <groupId>software.amazon.awssdk</groupId>
+ <artifactId>url-connection-client</artifactId>
+ </exclusion>
+ </exclusions>
+</dependency>
+```
+
+Next, add the `aws-crt-client` and exclude the "generic" `aws-crt` dependency (contains all runtime libraries).
+Instead, set a specific classifier of the `aws-crt` to use the one for your target runtime: either `linux-x86_64` for a Lambda configured for x86 or `linux-aarch_64` for Lambda using arm64.
+
+!!! note "You will need to add a separate maven profile to build and debug locally when your development environment does not share the target architecture you are using in Lambda."
+By specifying the specific target runtime, we prevent other target runtimes from being included in the jar file, resulting in a smaller Lambda package and improved cold start times.
+
+```xml
+<dependencies>
+ <dependency>
+ <groupId>software.amazon.awssdk</groupId>
+ <artifactId>aws-crt-client</artifactId>
+ <version>2.23.21</version>
+ <exclusions>
+ <exclusion>
+ <groupId>software.amazon.awssdk.crt</groupId>
+ <artifactId>aws-crt</artifactId>
+ </exclusion>
+ </exclusions>
+ </dependency>
+
+ <dependency>
+ <groupId>software.amazon.awssdk.crt</groupId>
+ <artifactId>aws-crt</artifactId>
+ <version>0.29.9</version>
+ <classifier>linux-x86_64</classifier>
+ </dependency>
+</dependencies>
+```
+
+### Explicitly set the AWS CRT HTTP Client
+
+After configuring the dependencies, it's required to explicitly specify the AWS SDK HTTP client.
+Depending on the utility you are using, there is a different way to configure the SDK client.
+
+The following example shows how to use the Parameters module while leveraging the AWS CRT Client.
+
+```java hl_lines="16 23-24"
+import static software.amazon.lambda.powertools.parameters.transform.Transformer.base64;
+
+import com.amazonaws.services.lambda.runtime.Context;
+import com.amazonaws.services.lambda.runtime.RequestHandler;
+import software.amazon.awssdk.services.ssm.SsmClient;
+import software.amazon.awssdk.http.crt.AwsCrtHttpClient;
+import software.amazon.lambda.powertools.parameters.ssm.SSMProvider;
+
+public class RequestHandlerWithParams implements RequestHandler<String, String> {
+
+ // Get an instance of the SSMProvider with a custom HTTP client (aws crt).
+ SSMProvider ssmProvider = SSMProvider
+ .builder()
+ .withClient(
+ SsmClient.builder()
+ .httpClient(AwsCrtHttpClient.builder().build())
+ .build()
+ )
+ .build();
+
+ public String handleRequest(String input, Context context) {
+ // Retrieve a single param
+ String value = ssmProvider
+ .get("/my/secret");
+ // We might instead want to retrieve multiple parameters at once, returning a Map of key/value pairs
+ // .getMultiple("/my/secret/path");
+
+ // Return the result
+ return value;
+ }
+}
+```
+
+The `aws-crt-client` was considered for adoption as the default HTTP client in Powertools for AWS Lambda (Java) as mentioned in [Move SDK http client to CRT](https://github.com/aws-powertools/powertools-lambda-java/issues/1092),
+but due to the impact on the developer experience it was decided to stick with the `url-connection-client`.
+
+## How can I use Powertools for AWS Lambda (Java) with GraalVM?
+
+Core utilities, i.e. [logging](./core/logging.md), [metrics](./core/metrics.md) and [tracing](./core/tracing.md), include the [GraalVM Reachability Metadata (GRM)](https://www.graalvm.org/latest/reference-manual/native-image/metadata/) in the `META-INF` directories of the respective JARs. You can find a working example of Serverless Application Model (SAM) based application in the [examples](../examples/powertools-examples-core-utilities/sam-graalvm/README.md) directory.
+
+Below, you find typical steps you need to follow in a Maven based Java project:
+
+### Set the environment to use GraalVM
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+```
+
+### Use log4j `>2.24.0`
+
+Log4j version `2.24.0` adds [support for GraalVM](https://github.com/apache/logging-log4j2/issues/1539#issuecomment-2106766878). Depending on your project's dependency hierarchy, older version of log4j might be included in the final dependency graph. Make sure version `>2.24.0` of these dependencies are used by your Maven project:
+
+```xml
+<dependencies>
+ <dependency>
+ <groupId>org.apache.logging.log4j</groupId>
+ <artifactId>log4j-api</artifactId>
+ <version>${log4j.version}</version>
+ </dependency>
+ <dependency>
+ <groupId>org.apache.logging.log4j</groupId>
+ <artifactId>log4j-core</artifactId>
+ <version>${log4j.version}</version>
+ </dependency>
+ <dependency>
+ <groupId>org.apache.logging.log4j</groupId>
+ <artifactId>log4j-slf4j2-impl</artifactId>
+ <version>${log4j.version}</version>
+ </dependency>
+ <dependency>
+ <groupId>org.apache.logging.log4j</groupId>
+ <artifactId>log4j-layout-template-json</artifactId>
+ <version>${log4j.version}</version>
+ </dependency>
+</dependencies>
+
+```
+
+### Add the AWS Lambda Java Runtime Interface Client dependency
+
+The Runtime Interface Client allows your function to receive invocation events from Lambda, send the response back to Lambda, and report errors to the Lambda service. Add the below dependency to your Maven project:
+
+```xml
+<dependency>
+ <groupId>com.amazonaws</groupId>
+ <artifactId>aws-lambda-java-runtime-interface-client</artifactId>
+ <version>2.1.1</version>
+</dependency>
+```
+
+Also include the AWS Lambda GRM files by copying the `com.amazonaws` [directory](../examples/powertools-examples-core-utilities/sam-graalvm/src/main/resources/META-INF/native-image/) in your project's `META-INF/native-image` directory
+
+### Build the native image
+
+Use the `native-maven-plugin` to build the native image. You can do this by adding the plugin to your `pom.xml` and creating a build profile called `native-image` that can build the native image of your Lambda function:
+
+```xml
+<profiles>
+ <profile>
+ <id>native-image</id>
+ <build>
+ <plugins>
+ <plugin>
+ <groupId>org.graalvm.buildtools</groupId>
+ <artifactId>native-maven-plugin</artifactId>
+ <version>0.10.1</version>
+ <extensions>true</extensions>
+ <executions>
+ <execution>
+ <id>build-native</id>
+ <goals>
+ <goal>build</goal>
+ </goals>
+ <phase>package</phase>
+ </execution>
+ </executions>
+ <configuration>
+ <imageName>your-project-name</imageName>
+ <mainClass>com.amazonaws.services.lambda.runtime.api.client.AWSLambda</mainClass>
+ <buildArgs>
+ <!-- required for AWS Lambda Runtime Interface Client -->
+ <arg>--enable-url-protocols=http</arg>
+ <arg>--add-opens java.base/java.util=ALL-UNNAMED</arg>
+ </buildArgs>
+ </configuration>
+ </plugin>
+ </plugins>
+ </build>
+ </profile>
+</profiles>
+```
+
+Create a Docker image using a `Dockerfile` like [this](../examples/powertools-examples-core-utilities/sam-graalvm/Dockerfile) to create an x86 based build image.
+
+```shell
+docker build --platform linux/amd64 . -t your-org/your-app-graalvm-builder
+```
+
+Create the native image of you Lambda function using the Docker command below.
+
+```shell
+docker run --platform linux/amd64 -it -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 your-org/your-app-graalvm-builder mvn clean -Pnative-image package
+
+```
+
+The native image is created in the `target/` directory.

+### Installation
+Depending on preference, you must choose to use either _log4j2_ or _logback_ as your log provider. If you use the AspectJ annotation approach, you must configure _aspectj_ to weave the code and make sure the annotation is processed. If you prefer the [functional approach](../usage-patterns.md#functional-approach), AspectJ configuration is not required.

- Configuring utiltiy using `<LambdaJsonLayout/>` plugin is deprecated now. While utility still supports the old configuration, we strongly recommend upgrading the
- `log4j2.xml` configuration to `JsonTemplateLayout` instead. [JsonTemplateLayout](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html) is recommended way of doing structured logging.

+
+
+### Configuration
+
+#### Main environment variables
+
+The logging module requires two settings:
+
+| Environment variable | Setting | Description |
+|---------------------------|-------------------|-------------------------------------------------------------------------------------------------------------|
+| `POWERTOOLS_LOG_LEVEL` | **Logging level** | Sets how verbose Logger should be. If not set, will use the [Logging configuration](#logging-configuration) |
+| `POWERTOOLS_SERVICE_NAME` | **Service** | Sets service key that will be included in all log statements (Default is `service_undefined`) |
+
+Here is an example using AWS Serverless Application Model (SAM):
+
+=== "template.yaml"
+``` yaml hl_lines="10 11"
+Resources:
+ PaymentFunction:
+ Type: AWS::Serverless::Function
+ Properties:
+ MemorySize: 512
+ Timeout: 20
+ Runtime: java17
+ Environment:
+ Variables:
+ POWERTOOLS_LOG_LEVEL: WARN
+ POWERTOOLS_SERVICE_NAME: payment
+```
+
+There are some other environment variables which can be set to modify Logging's settings at a global scope:
+
+| Environment variable | Type | Description |
+|---------------------------------|----------|-------------------------------------------------------------------------------------------------------------------------|
+| `POWERTOOLS_LOGGER_SAMPLE_RATE` | float | Configure the sampling rate at which `DEBUG` logs should be included. See [sampling rate](#sampling-debug-logs) |
+| `POWERTOOLS_LOGGER_LOG_EVENT` | boolean | Specify if the incoming Lambda event should be logged. See [Logging event](#logging-incoming-event) |
+| `POWERTOOLS_LOGGER_LOG_RESPONSE` | boolean | Specify if the Lambda response should be logged. See [logging response](#logging-handler-response) |
+| `POWERTOOLS_LOGGER_LOG_ERROR` | boolean | Specify if a Lambda uncaught exception should be logged. See [logging exception](#logging-handler-uncaught-exception ) |
+
+#### Logging configuration
+
+Powertools for AWS Lambda (Java) simply extends the functionality of the underlying library you choose (_log4j2_ or _logback_).
+You can leverage the standard configuration files (_log4j2.xml_ or _logback.xml_):
=== "log4j2.xml"
+ With log4j2, we leverage the [`JsonTemplateLayout`](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html){target="_blank"}
+ to provide structured logging. A default template is provided in powertools ([_LambdaJsonLayout.json_](https://github.com/aws-powertools/powertools-lambda-java/blob/4444b4bce8eb1cc19880d1c1ef07188d97de9126/powertools-logging/powertools-logging-log4j/src/main/resources/LambdaJsonLayout.json){target="_blank"}):

+ </configuration>
```
-You can also explicitly set a service name via **`POWERTOOLS_SERVICE_NAME`** env var. This sets **service** key that will be present across all log statements.
+## Log level
+Log level is generally configured in the `log4j2.xml` or `logback.xml`. But this level is static and needs a redeployment of the function to be changed.
+Powertools for AWS Lambda permits to change this level dynamically thanks to an environment variable `POWERTOOLS_LOG_LEVEL`.
-## Standard structured keys
+We support the following log levels (SLF4J levels): `TRACE`, `DEBUG`, `INFO`, `WARN`, `ERROR`.
+If the level is set to `CRITICAL` (supported in log4j but not logback), we revert it back to `ERROR`.
+If the level is set to any other value, we set it to the default value (`INFO`).
-Your logs will always include the following keys to your structured logging:
+### AWS Lambda Advanced Logging Controls (ALC)
-Key | Type | Example | Description
-------------------------------------------------- | ------------------------------------------------- | --------------------------------------------------------------------------------- | -------------------------------------------------
-**timestamp** | String | "2020-05-24 18:17:33,774" | Timestamp of actual log statement

-**coldStart** | Boolean | true| ColdStart value.
-**service** | String | "payment" | Service name defined. "service_undefined" will be used if unknown
-**samplingRate** | int | 0.1 | Debug logging sampling rate in percentage e.g. 10% in this case

+!!!question "When is it useful?"
+ When you want to set a logging policy to drop informational or verbose logs for one or all AWS Lambda functions, regardless of runtime and logger used.
-## Capturing context Lambda info
+<!-- markdownlint-disable MD013 -->
+With [AWS Lambda Advanced Logging Controls (ALC)](https://docs.aws.amazon.com/lambda/latest/dg/monitoring-cloudwatchlogs.html#monitoring-cloudwatchlogs-advanced){target="_blank"}, you can enforce a minimum log level that Lambda will accept from your application code.
-You can enrich your structured logs with key Lambda context information via `logEvent` annotation parameter.
-You can also explicitly log any incoming event using `logEvent` param. Refer [Override default object mapper](#override-default-object-mapper)
-to customise what is logged.
+When enabled, you should keep your own log level and ALC log level in sync to avoid data loss.
-!!! warning
- Log event is disabled by default to prevent sensitive info being logged.
+Here's a sequence diagram to demonstrate how ALC will drop both `INFO` and `DEBUG` logs emitted from `Logger`, when ALC log level is stricter than `Logger`.
+<!-- markdownlint-enable MD013 -->
+```mermaid

+ Lambda function-->>Application Logger: logger.info("Something happened")
+ Lambda service--xLambda service: DROP INFO and DEBUG logs
+ Lambda service->>CloudWatch Logs: Ingest error logs
+```
+
+### Priority of log level settings in Powertools for AWS Lambda
+
+We prioritise log level settings in this order:
+
+1. `AWS_LAMBDA_LOG_LEVEL` environment variable
+2. `POWERTOOLS_LOG_LEVEL` environment variable
+3. level defined in the `log4j2.xml` or `logback.xml` files
+
+If you set `POWERTOOLS_LOG_LEVEL` lower than ALC, we will emit a warning informing you that your messages will be discarded by Lambda.
+
+!!! note
+ With ALC enabled, we are unable to increase the minimum log level below the `AWS_LAMBDA_LOG_LEVEL` environment variable value, see [AWS Lambda service documentation](https://docs.aws.amazon.com/lambda/latest/dg/monitoring-cloudwatchlogs.html#monitoring-cloudwatchlogs-log-level){target="_blank"} for more details.
+
+## Basic Usage
+
+You can use Powertools for AWS Lambda Logging with either the `@Logging` annotation or the functional API:
+
+=== "@Logging annotation"
+
+ ```java hl_lines="8 10 12 14"
+ import org.slf4j.Logger;
+ import org.slf4j.LoggerFactory;
import software.amazon.lambda.powertools.logging.Logging;
- ...
-
- /**
- * Handler for requests to Lambda function.
- */
- public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
-
- Logger log = LogManager.getLogger();
+ // ... other imports
+
+ public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
@Logging
public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
- ...
+ LOGGER.info("Collecting payment");
+ // ...
+ LOGGER.debug("order={}, amount={}", order.getId(), order.getAmount());
+ // ...
}
}
```
-=== "AppLogEvent.java"
-
- ```java hl_lines="8"
- /**
- * Handler for requests to Lambda function.
- */
- public class AppLogEvent implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+=== "Functional API"
+
+ ```java hl_lines="8 11 12 14 17"
+ import org.slf4j.Logger;
+ import org.slf4j.LoggerFactory;
+ import software.amazon.lambda.powertools.logging.PowertoolsLogging;
+ // ... other imports
+
+ public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
- Logger log = LogManager.getLogger();
+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
- @Logging(logEvent = true)
public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
- ...
+ return PowertoolsLogging.withLogging(context, () -> {
+ LOGGER.info("Collecting payment");
+ // ...
+ LOGGER.debug("order={}, amount={}", order.getId(), order.getAmount());
+ // ...
+ return new APIGatewayProxyResponseEvent().withStatusCode(200);
+ });
}
}
```
-### Customising fields in logs
+## Standard structured keys
-- Utility by default emits `timestamp` field in the logs in format `yyyy-MM-dd'T'HH:mm:ss.SSSZz` and in system default timezone.
-If you need to customize format and timezone, you can do so by configuring `log4j2.component.properties` and configuring properties as shown in example below:
+Your logs will always include the following keys in your structured logging:
-=== "log4j2.component.properties"
+| Key | Type | Example | Description |
+|-------------------|--------|-----------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------|
+| **timestamp** | String | "2023-12-01T14:49:19.293Z" | Timestamp of actual log statement, by default uses default AWS Lambda timezone (UTC) |
+| **level** | String | "INFO" | Logging level (any level supported by _SLF4J_ (i.e. `TRACE`, `DEBUG`, `INFO`, `WARN`, `ERROR`) |
+| **service** | String | "payment" | Service name defined, by default `service_undefined` |
+| **sampling_rate** | float | 0.1 | Debug logging sampling rate in percentage e.g. 10% in this case (logged if not 0) |
+| **message** | String | "Collecting payment" | Log statement value. Unserializable JSON values will be casted to string |
+| **xray_trace_id** | String | "1-5759e988-bd862e3fe1be46a994272793" | X-Ray Trace ID when [Tracing is enabled](https://docs.aws.amazon.com/lambda/latest/dg/services-xray.html){target="_blank"} |
+| **error** | Map | `{ "name": "InvalidAmountException", "message": "Amount must be superior to 0", "stack": "at..." }` | Eventual exception (e.g. when doing `logger.error("Error", new InvalidAmountException("Amount must be superior to 0"));`) |
- ```properties hl_lines="1 2"
- log4j.layout.jsonTemplate.timestampFormatPattern=yyyy-MM-dd'T'HH:mm:ss.SSSZz
- log4j.layout.jsonTemplate.timeZone=Europe/Oslo
- ```
+???+ note
+ If you emit a log message with a key that matches one of the [standard structured keys](#standard-structured-keys) or one of the [additional structured keys](#additional-structured-keys), the Logger will log a warning message and ignore the key.
-- Utility also provides sample template for [Elastic Common Schema(ECS)](https://www.elastic.co/guide/en/ecs/current/ecs-reference.html) layout.
-The field emitted in logs will follow specs from [ECS](https://www.elastic.co/guide/en/ecs/current/ecs-reference.html) together with field captured by utility as mentioned [above](#standard-structured-keys).
+## Additional structured keys
- Use `LambdaEcsLayout.json` as `eventTemplateUri` when configuring `JsonTemplateLayout`.
+### Logging Lambda context information
+The following keys will also be added to all your structured logs (unless [configured otherwise](#more-customization_1)):
-=== "log4j2.xml"
+| Key | Type | Example | Description |
+|--------------------------|---------|----------------------------------------------------------------------------------------|------------------------------------|
+| **cold_start** | Boolean | false | ColdStart value |
+| **function_name** | String | "example-PaymentFunction-1P1Z6B39FLU73" | Name of the function |
+| **function_version** | String | "12" | Version of the function |
+| **function_memory_size** | String | "512" | Memory configure for the function |
+| **function_arn** | String | "arn:aws:lambda:eu-west-1:012345678910:function:example-PaymentFunction-1P1Z6B39FLU73" | ARN of the function |
+| **function_request_id** | String | "899856cb-83d1-40d7-8611-9e78f15f32f4"" | AWS Request ID from lambda context |

+???+ warning "Do not use reserved keys in `StructuredArguments`"
+ If the key name of your structured argument matches any of the [standard structured keys](#standard-structured-keys) or any of the [additional structured keys](#additional-structured-keys), the Logger will log a warning message and ignore the key. This is to protect you from accidentally overwriting reserved keys such as the log level or Lambda context information.
+
+**Using MDC**
-Logger is commonly initialized in the global scope. Due to [Lambda Execution Context reuse](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-context.html),
-this means that custom keys can be persisted across invocations. If you want all custom keys to be deleted, you can use
-`clearState=true` attribute on `@Logging` annotation.
+Mapped Diagnostic Context (MDC) is essentially a Key-Value store. It is supported by the [SLF4J API](https://www.slf4j.org/manual.html#mdc){target="_blank"},
+[logback](https://logback.qos.ch/manual/mdc.html){target="_blank"} and log4j (known as [ThreadContext](https://logging.apache.org/log4j/2.x/manual/thread-context.html){target="_blank"}). You can use the following standard:
+`MDC.put("key", "value");`
-=== "App.java"
+???+ warning "Custom keys stored in the MDC are persisted across warm invocations"
+ Always set additional keys as part of your handler method to ensure they have the latest value, or explicitly clear them with [`clearState=true`](#clearing-state).

+ Avoid adding any of the keys listed in [standard structured keys](#standard-structured-keys) and [additional structured keys](#additional-structured-keys) to your MDC.

-## Override default object mapper
+`clearState` is based on `MDC.clear()`. State clearing is automatically done at the end of the execution of the handler if set to `true`.
-You can optionally choose to override default object mapper which is used to serialize lambda function events. You might
-want to supply custom object mapper in order to control how serialisation is done, for example, when you want to log only
-specific fields from received event due to security.

+## Advanced
-## Upgrade to JsonTemplateLayout from deprecated LambdaJsonLayout configuration in log4j2.xml
+### Buffering logs
-Prior to version [1.10.0](https://github.com/awslabs/aws-lambda-powertools-java/releases/tag/v1.10.0), only supported way of configuring `log4j2.xml` was via `<LambdaJsonLayout/>`. This plugin is
-deprecated now and will be removed in future version. Switching to `JsonTemplateLayout` is straight forward.
+Log buffering enables you to buffer logs for a specific request or invocation. Enable log buffering by configuring the `BufferingAppender` in your logging configuration. You can buffer logs at the `WARNING`, `INFO` or `DEBUG` level, and flush them automatically on error or manually as needed.
-Below examples shows deprecated and new configuration of `log4j2.xml`.
+!!! tip "This is useful when you want to reduce the number of log messages emitted while still having detailed logs when needed, such as when troubleshooting issues."

+
+#### Configuring the buffer
+
+When configuring log buffering, you have options to fine-tune how logs are captured, stored, and emitted. You can configure the following parameters in the `BufferingAppender` configuration:
+
+| Parameter | Description | Configuration |
+| --------------------- | ----------------------------------------------- | ---------------------------- |
+| `maxBytes` | Maximum size of the log buffer in bytes | `int` (default: 20480 bytes) |
+| `bufferAtVerbosity` | Minimum log level to buffer | `DEBUG` (default), `INFO`, `WARNING` |
+| `flushOnErrorLog` | Automatically flush buffer when `ERROR` or `FATAL` level logs are emitted | `true` (default), `false` |
+
+!!! warning "Logger Level Configuration"
+ To use log buffering effectively, you must set your logger levels to the same level as `bufferAtVerbosity` or more verbose for the logging framework to capture and forward logs to the `BufferingAppender`. For example, if you want to buffer `DEBUG` level logs and emit `INFO`+ level logs directly, you must:
+
+ - Set your logger levels to `DEBUG` in your log4j2.xml or logback.xml configuration
+ - Set `POWERTOOLS_LOG_LEVEL=DEBUG` if using the environment variable (see [Log level](#log-level) section for more details)
+
+ If you want to sample `INFO` and `WARNING` logs but not `DEBUG` logs, set your log level to `INFO` and `bufferAtVerbosity` to `WARNING`. This allows you to define the lower and upper bounds for buffering. All logs with a more severe level than `bufferAtVerbosity` will be emitted directly.

+ ```
+
+!!! note "Disabling `flushOnErrorLog` will not flush the buffer when logging an error. This is useful when you want to control when the buffer is flushed by calling the flush method manually."
+
+#### Manual buffer control
+
+You can manually control the log buffer using the `PowertoolsLogging` utility class, which provides a backend-independent API that works with both Log4j2 and Logback:
+
+=== "Manual flush"
+
+ ```java hl_lines="1 12-13"
+ import software.amazon.lambda.powertools.logging.PowertoolsLogging;
+
+ public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
+ @Logging
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ LOGGER.debug("Processing payment"); // this is buffered
+ LOGGER.info("Payment validation complete"); // this is buffered
+
+ // Manually flush all buffered logs
+ PowertoolsLogging.flushBuffer();
+
+ return new APIGatewayProxyResponseEvent().withStatusCode(200);
+ }
+ }
+ ```
+
+=== "Manual clear"
+
+ ```java hl_lines="1 12-13"
+ import software.amazon.lambda.powertools.logging.PowertoolsLogging;
+
+ public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
+ @Logging
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ LOGGER.debug("Processing payment"); // this is buffered
+ LOGGER.info("Payment validation complete"); // this is buffered
+
+ // Manually clear buffered logs without outputting them
+ PowertoolsLogging.clearBuffer();
+
+ return new APIGatewayProxyResponseEvent().withStatusCode(200);
+ }
+ }
+ ```
+
+**Available methods:**
+
+- `#!java PowertoolsLogging.flushBuffer()` - Outputs all buffered logs and clears the buffer
+- `#!java PowertoolsLogging.clearBuffer()` - Discards all buffered logs without outputting them
+
+#### Flushing on exceptions
+
+Use the `@Logging` annotation to automatically flush buffered logs when an uncaught exception is raised in your Lambda function. This is enabled by default (`flushBufferOnUncaughtError = true`), but you can explicitly configure it if needed.
+
+???+ warning
+ This feature is only available when using the `@Logging` annotation. When using the functional API, you must manually flush the buffer in exception handlers.
+
+=== "@Logging annotation"
+
+ ```java hl_lines="5 11"
+ public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
+ @Logging(flushBufferOnUncaughtError = true)
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ LOGGER.debug("a debug log"); // this is buffered
+
+ // do stuff
+
+ throw new RuntimeException("Something went wrong"); // Logs will be flushed here
+ }
+ }
+ ```

+ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ return PowertoolsLogging.withLogging(context, () -> {
+ try {
+ LOGGER.debug("a debug log"); // this is buffered
+ // do stuff
+ throw new RuntimeException("Something went wrong");
+ } catch (Exception e) {

+
+#### Buffering FAQs
+
+1. **Does the buffer persist across Lambda invocations?** No, each Lambda invocation has its own buffer. The buffer is initialized when the Lambda function is invoked and is cleared after the function execution completes or when flushed manually.
+2. **Are my logs buffered during cold starts (INIT phase)?** No, we never buffer logs during cold starts. This is because we want to ensure that logs emitted during this phase are always available for debugging and monitoring purposes. The buffer is only used during the execution of the Lambda function.
+3. **How can I prevent log buffering from consuming excessive memory?** You can limit the size of the buffer by setting the `maxBytes` option in the `BufferingAppender` configuration. This will ensure that the buffer does not grow indefinitely.
+4. **What happens if the log buffer reaches its maximum size?** Older logs are removed from the buffer to make room for new logs. This means that if the buffer is full, you may lose some logs if they are not flushed before the buffer reaches its maximum size. When this happens, we emit a warning when flushing the buffer to indicate that some logs have been dropped.
+5. **How is the log size of a log line calculated?** The log size is calculated based on the size of the log line in bytes. This includes the size of the log message, any exception (if present), the log line location, additional keys, and the timestamp.
+6. **What timestamp is used when I flush the logs?** The timestamp is the original time when the log record was created. If you create a log record at 11:00:10 and flush it at 11:00:25, the log line will retain its original timestamp of 11:00:10.
+7. **What happens if I try to add a log line that is bigger than max buffer size?** The log will be emitted directly to standard output and not buffered. When this happens, we emit a warning to indicate that the log line was too big to be buffered.
+8. **What happens if Lambda times out without flushing the buffer?** Logs that are still in the buffer will be lost.
+9. **How does the `BufferingAppender` work with different appenders?** The `BufferingAppender` is designed to wrap arbitrary appenders, providing maximum flexibility. You can wrap console appenders, file appenders, or any custom appenders with buffering functionality.
+
+## Sampling debug logs
+
+You can dynamically set a percentage of your logs to`DEBUG` level to be included in the logger output, regardless of configured log level, using the`POWERTOOLS_LOGGER_SAMPLE_RATE` environment variable,
+via the `samplingRate` attribute on the `@Logging` annotation, or as a parameter in the functional API.
+
+!!! info
+ Configuration via environment variable is given precedence over sampling rate configuration, provided it's in valid value range.
+
+=== "@Logging annotation"
+
+ ```java hl_lines="5"
+ public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ private static final Logger LOGGER = LoggerFactory.getLogger(App.class);
+
+ @Logging(samplingRate = 0.5)
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ // will eventually be logged based on the sampling rate
+ LOGGER.debug("Handle payment");
+ }
+ }
+ ```
+
+=== "Functional API"
+
+ ```java hl_lines="6"
+ public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ private static final Logger LOGGER = LoggerFactory.getLogger(App.class);
+
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ return PowertoolsLogging.withLogging(context, 0.5, () -> {
+ // will eventually be logged based on the sampling rate
+ LOGGER.debug("Handle payment");
+ return new APIGatewayProxyResponseEvent().withStatusCode(200);
+ });
+ }
+ }
+ ```

+ PaymentFunction:
+ Type: AWS::Serverless::Function
+ Properties:
+ ...
+ Environment:

+
+ ```
+
+## Built-in Correlation ID expressions
+
+You can use any of the following built-in JMESPath expressions with the `@Logging` annotation or the functional API:
+
+???+ note "Note: Any object key named with `-` must be escaped"
+ For example, **`request.headers."x-amzn-trace-id"`**.
+
+| Name | Expression | Description |
+|-------------------------------|-------------------------------------|---------------------------------|
+| **API_GATEWAY_REST** | `"requestContext.requestId"` | API Gateway REST API request ID |
+| **API_GATEWAY_HTTP** | `"requestContext.requestId"` | API Gateway HTTP API request ID |
+| **APPSYNC_RESOLVER** | `request.headers."x-amzn-trace-id"` | AppSync X-Ray Trace ID |
+| **APPLICATION_LOAD_BALANCER** | `headers."x-amzn-trace-id"` | ALB X-Ray Trace ID |
+| **EVENT_BRIDGE** | `"id"` | EventBridge Event ID |
+
+
+## Customising fields in logs
+
+Powertools for AWS Lambda comes with default json structure ([standard fields](#standard-structured-keys) & [lambda context fields](#logging-lambda-context-information)).
+
+You can go further and customize which fields you want to keep in your logs or not. The configuration varies according to the underlying logging library.
+
+### Log4j2 configuration
+Log4j2 configuration is done in _log4j2.xml_ and leverages `JsonTemplateLayout`:
+
+```xml
+ <Console name="console" target="SYSTEM_OUT">
+ <JsonTemplateLayout eventTemplateUri="classpath:LambdaJsonLayout.json" />
+ </Console>
+```
+
+The `JsonTemplateLayout` is automatically configured with the provided template:
+
+??? example "LambdaJsonLayout.json"
+ ```json
+ {
+ "level": {
+ "$resolver": "level",
+ "field": "name"
+ },
+ "message": {
+ "$resolver": "message"
+ },
+ "error": {
+ "message": {
+ "$resolver": "exception",
+ "field": "message"
+ },
+ "name": {
+ "$resolver": "exception",
+ "field": "className"
+ },
+ "stack": {
+ "$resolver": "exception",
+ "field": "stackTrace",
+ "stackTrace": {
+ "stringified": true
+ }
+ }
+ },
+ "cold_start": {
+ "$resolver": "powertools",
+ "field": "cold_start"
+ },
+ "function_arn": {
+ "$resolver": "powertools",
+ "field": "function_arn"
+ },
+ "function_memory_size": {
+ "$resolver": "powertools",
+ "field": "function_memory_size"
+ },
+ "function_name": {
+ "$resolver": "powertools",
+ "field": "function_name"
+ },
+ "function_request_id": {
+ "$resolver": "powertools",
+ "field": "function_request_id"
+ },
+ "function_version": {
+ "$resolver": "powertools",
+ "field": "function_version"
+ },
+ "sampling_rate": {
+ "$resolver": "powertools",
+ "field": "sampling_rate"
+ },
+ "service": {
+ "$resolver": "powertools",
+ "field": "service"
+ },
+ "timestamp": {
+ "$resolver": "timestamp",
+ "pattern": {
+ "format": "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
+ }
+ },
+ "xray_trace_id": {
+ "$resolver": "powertools",
+ "field": "xray_trace_id"
+ },
+ "correlation_id": {
+ "$resolver": "powertools",
+ "field": "correlation_id"
+ },
+ "": {
+ "$resolver": "powertools"
+ }
+ }
+ ```
+
+You can create your own template and leverage the [PowertoolsResolver](https://github.com/aws-powertools/powertools-lambda-java/tree/v2/powertools-logging/powertools-logging-log4j/src/main/java/org/apache/logging/log4j/layout/template/json/resolver/PowertoolsResolver.java){target="_blank"}
+and any other resolver to log the desired fields with the desired format. Some examples of customization are given below:
+
+#### Customising date format
+
+Utility by default emits `timestamp` field in the logs in format `yyyy-MM-dd'T'HH:mm:ss.SSS'Z'` and in system default timezone.
+If you need to customize format and timezone, you can update your template.json or by configuring `log4j2.component.properties` as shown in examples below:
+
+=== "my-custom-template.json"
+
+ ```json
+ {
+ "timestamp": {
+ "$resolver": "timestamp",
+ "pattern": {
+ "format": "yyyy-MM-dd HH:mm:ss",
+ "timeZone": "Europe/Paris",
+ }
+ },
+ }
+ ```
+
+=== "log4j2.component.properties"
+
+ ```properties hl_lines="1 2"
+ log4j.layout.jsonTemplate.timestampFormatPattern=yyyy-MM-dd'T'HH:mm:ss.SSSZz
+ log4j.layout.jsonTemplate.timeZone=Europe/Oslo
+ ```
+
+See [`TimestampResolver` documentation](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html#event-template-resolver-timestamp){target="_blank"} for more details.
+
+???+ warning "Lambda Advanced Logging Controls date format"
+ When using the Lambda ALC, you must have a date format compatible with the [RFC3339](https://www.rfc-editor.org/rfc/rfc3339)
+
+#### More customization
+You can also customize how [exceptions are logged](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html#event-template-resolver-exception){target="_blank"}, and much more.
+See the [JSON Layout template documentation](https://logging.apache.org/log4j/2.x/manual/json-template-layout.html){target="_blank"} for more details.
+
+### Logback configuration
+Logback configuration is done in _logback.xml_ and the `LambdaJsonEncoder`:
+
+```xml
+ <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
+ <encoder class="software.amazon.lambda.powertools.logging.logback.LambdaJsonEncoder">
+ </encoder>
+ </appender>
+```
+
+The `LambdaJsonEncoder` can be customized in different ways:
+
+#### Customising date format
+Utility by default emits `timestamp` field in the logs in format `yyyy-MM-dd'T'HH:mm:ss.SSS'Z'` and in system default timezone.
+If you need to customize format and timezone, you can change use the following:
+
+```xml
+ <encoder class="software.amazon.lambda.powertools.logging.logback.LambdaJsonEncoder">
+ <timestampFormat>yyyy-MM-dd HH:mm:ss</timestampFormat>
+ <timestampFormatTimezoneId>Europe/Paris</timestampFormatTimezoneId>
+ </encoder>
+```
+
+#### More customization
+
+- You can use a standard `ThrowableHandlingConverter` to customize the exception format (default is no converter). Example:
+
+```xml
+ <encoder class="software.amazon.lambda.powertools.logging.logback.LambdaJsonEncoder">
+ <throwableConverter class="net.logstash.logback.stacktrace.ShortenedThrowableConverter">
+ <maxDepthPerThrowable>30</maxDepthPerThrowable>
+ <maxLength>2048</maxLength>
+ <shortenedClassNameLength>20</shortenedClassNameLength>
+ <exclude>sun\.reflect\..*\.invoke.*</exclude>
+ <exclude>net\.sf\.cglib\.proxy\.MethodProxy\.invoke</exclude>
+ <evaluator class="myorg.MyCustomEvaluator"/>
+ <rootCauseFirst>true</rootCauseFirst>
+ <inlineHash>true</inlineHash>
+ </throwableConverter>
+ </encoder>
+```
+
+- You can choose to add information about threads (default is `false`):
+
+```xml
+ <encoder class="software.amazon.lambda.powertools.logging.logback.LambdaJsonEncoder">
+ <includeThreadInfo>true</includeThreadInfo>
+ </encoder>
+```
+
+- You can even choose to remove Powertools information from the logs like function name, arn:
+
+```xml
+ <encoder class="software.amazon.lambda.powertools.logging.logback.LambdaJsonEncoder">
+ <includePowertoolsInfo>false</includePowertoolsInfo>
+ </encoder>
+```
+
+## Elastic Common Schema (ECS) Support
+
+Utility also supports [Elastic Common Schema(ECS)](https://www.elastic.co/guide/en/ecs/current/ecs-reference.html){target="_blank"} format.
+The field emitted in logs will follow specs from [ECS](https://www.elastic.co/guide/en/ecs/current/ecs-reference.html){target="_blank"} together with field captured by utility as mentioned [above](#standard-structured-keys).
+
+### Log4j2 configuration
+
+Use `LambdaEcsLayout.json` as `eventTemplateUri` when configuring `JsonTemplateLayout`.
+
+=== "log4j2.xml"
+
+ ```xml hl_lines="5"
+ <?xml version="1.0" encoding="UTF-8"?>

+3. Environment variables (recommended)
+
+For most use-cases, we recommend using Environment variables and only overwrite settings in code where needed using either the `@FlushMetrics` annotation or `MetricsBuilder` if the annotation cannot be used.

+`Metrics` is implemented as a Singleton to keep track of your aggregate metrics in memory and make them accessible anywhere in your code. The `@FlushMetrics` annotation automatically flushes metrics at the end of the Lambda handler execution. Alternatively, you can use the functional approach and manually flush metrics using `metrics.flush()`.

+
+### Usage without `@FlushMetrics` annotation
+
+You can use the **functional API** approach (see [usage patterns](../usage-patterns.md#functional-approach)) to work with Metrics without the `@FlushMetrics` annotation. The `Metrics` Singleton provides all configuration options via `MetricsBuilder`. This approach eliminates the AspectJ runtime dependency and is useful if you work in an environment or with a framework that does not leverage the vanilla Lambda `handleRequest` method.
+
+!!!info "The environment variables for Service and Namespace configuration still apply but can be overwritten with `MetricsBuilder` if needed."
+
+The following example shows how to configure a custom `Metrics` Singleton using the Builder pattern. With the functional approach, you must manually flush metrics using `metrics.flush()`.
=== "App.java"
- ```java hl_lines="7 8 9"
- import static software.amazon.lambda.powertools.metrics.MetricsUtils.withSingleMetric;
+ ```java hl_lines="7-12 19 24"
+ import software.amazon.lambda.powertools.metrics.Metrics;
+ import software.amazon.lambda.powertools.metrics.MetricsBuilder;
+ import software.amazon.lambda.powertools.metrics.model.DimensionSet;
+ import software.amazon.lambda.powertools.metrics.model.MetricUnit;
public class App implements RequestHandler<Object, Object> {
+ // Create and configure a Metrics singleton using the functional approach
+ private static final Metrics metrics = MetricsBuilder.builder()
+ .withNamespace("ServerlessAirline")
+ .withRaiseOnEmptyMetrics(true)
+ .withService("payment")
+ .build();
@Override
public Object handleRequest(Object input, Context context) {
- withSingleMetric("CustomMetrics2", 1, Unit.COUNT, "Another", (metric) -> {
- metric.setDimensions(DimensionSet.of("AnotherService", "CustomService"));
- });
+ // You can manually capture the cold start metric
+ // Lambda context is an optional argument if not available in your environment
+ // Dimensions are also optional.
+ metrics.captureColdStartMetric(context, DimensionSet.of("FunctionName", "MyFunction", "Service", "payment"));
+
+ // Add metrics
+ metrics.addMetric("CustomMetric", 1, MetricUnit.COUNT);
+ // Manually flush metrics
+ metrics.flush();
+ }
+ }
+ ```
+
+## Testing your code
+
+### Suppressing metrics output
+
+If you would like to suppress metrics output during your unit tests, you can use the `POWERTOOLS_METRICS_DISABLED` environment variable. For example, using Maven you can set in your build plugins:
+
+```xml
+<plugin>
+ <groupId>org.apache.maven.plugins</groupId>
+ <artifactId>maven-surefire-plugin</artifactId>
+ <configuration>
+ <environmentVariables>
+ <POWERTOOLS_METRICS_DISABLED>true</POWERTOOLS_METRICS_DISABLED>
+ </environmentVariables>
+ </configuration>
+</plugin>
+```
+
+### Asserting EMF output
+
+When unit testing your code, you can run assertions against the output generated by the `Metrics` Singleton. For the `EmfMetricsLogger`, you can assert the generated JSON blob following the [CloudWatch EMF specification](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format.html) against your expected output.
+
+Make sure to set a test metrics namespace and service name to run assertions against metrics. For example, by setting the following environment variables in your tests:
+
+```xml
+<plugin>
+ <groupId>org.apache.maven.plugins</groupId>
+ <artifactId>maven-surefire-plugin</artifactId>
+ <configuration>
+ <environmentVariables>
+ <POWERTOOLS_SERVICE_NAME>TestService</POWERTOOLS_SERVICE_NAME>
+ <POWERTOOLS_METRICS_NAMESPACE>TestNamespace</POWERTOOLS_METRICS_NAMESPACE>
+ </environmentVariables>
+ </configuration>
+</plugin>
+```
+
+Consider the following example where we redirect the standard output to a custom `PrintStream`. We use the Jackson library to parse the EMF output into a `JsonNode` and run assertions against that.

-User should make sure to instrument the SDK clients explicitly based on the function dependency. Refer details on

+### AWS SDK for Java 2.x
+
+Powertools for AWS Lambda (Java) includes the `aws-xray-recorder-sdk-aws-sdk-v2-instrumentor` library, which **automatically instruments all AWS SDK v2 clients** when you add the `powertools-tracing` dependency to your project. This means downstream calls to AWS services are traced without any additional configuration.
+
+If you need more control over which clients are instrumented, you can manually add the `TracingInterceptor` to specific clients:
+

+
+ ```java hl_lines="1 2 3 8 9 10 11"

+
+For more details, refer to the [AWS X-Ray documentation on tracing AWS SDK calls](https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-java-awssdkclients.html) and [outgoing HTTP calls](https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-java-httpclients.html).
+
+## Testing your code
+
+When using `@Tracing` annotation, your Junit test cases needs to be configured to create parent Segment required by [AWS X-Ray SDK for Java](https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-java.html).
+
+Below are two ways in which you can configure your tests.
+
+#### Configure environment variable on project level (Recommended)
+
+You can choose to configure environment variable on project level for your test cases run. This is recommended approach as it will avoid the need of configuring each test case specifically.
+
+Below are examples configuring your maven/gradle projects. You can choose to configure it differently as well as long as you are making sure that environment variable `LAMBDA_TASK_ROOT` is set. This variable is
+used internally via AWS X-Ray SDK to configure itself properly for lambda runtime.
+
+=== "Maven (pom.xml)"
+
+ ```xml
+ <build>
+ ...
+ <plugins>
+ <!-- Configures environment variable to avoid initialization of AWS X-Ray segments for each tests-->
+ <plugin>
+ <groupId>org.apache.maven.plugins</groupId>
+ <artifactId>maven-surefire-plugin</artifactId>
+ <configuration>
+ <environmentVariables>
+ <LAMBDA_TASK_ROOT>handler</LAMBDA_TASK_ROOT>
+ </environmentVariables>
+ </configuration>
+ </plugin>
+ </plugins>
+ </build>
+
+ ```
+
+=== "Gradle (build.gradle)"
+
+ ```json
+ // Configures environment variable to avoid initialization of AWS X-Ray segments for each tests
+ test {
+ environment "LAMBDA_TASK_ROOT", "handler"
+ }
+ ```
+
+#### Configure test cases (Not Recommended)
+
+You can choose to configure each of your test case instead as well if you choose not to configure environment variable on project level.
+Below is an example configuration needed for each test case.
+
+=== "AppTest.java"
+
+ ```java hl_lines="10 11 12 17 18 19 20 21 22 23 24"
+ import com.amazonaws.xray.AWSXRay;
+ import org.junit.After;
+ import org.junit.Before;
+ import org.junit.Test;
+
+ public class AppTest {
+
+ @Before
+ public void setup() {
+ if(null == System.getenv("LAMBDA_TASK_ROOT")) {
+ AWSXRay.beginSegment("test");
+ }
+ }
+
+ @After
+ public void tearDown() {
+ // Needed when using sam build --use-container
+ if (AWSXRay.getCurrentSubsegmentOptional().isPresent()) {
+ AWSXRay.endSubsegment();
+ }
+
+ if(null == System.getenv("LAMBDA_TASK_ROOT")) {
+ AWSXRay.endSegment();
+ }
+ }
+

+???+ tip "Don't want to use AspectJ?"
+ Powertools for AWS Lambda (Java) now provides a functional API that doesn't require AspectJ configuration. Learn more about the [functional approach](./usage-patterns.md#functional-approach).
+
+### Java Compatibility
+Powertools for AWS Lambda (Java) supports all Java versions from 11 to 25 in line with the [corresponding Lambda runtimes](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html).
+
+In addition to the functional approach, [Logging](./core/logging.md), [Metrics](./core/metrics.md), [Tracing](./core/tracing.md), [Parameters](./utilities/parameters.md), [Idempotency](./utilities/idempotency.md), [Validation](./utilities/validation.md), and [Large Messages](./utilities/large_messages.md) utilities support annotations using AspectJ, which require configuration of the `aspectjrt` runtime library.
+
+You may need to add the appropriate version of `aspectjrt` to your dependencies based on the JDK used for building your function:
+
+```xml
+<dependency>
+ <groupId>org.aspectj</groupId>
+ <artifactId>aspectjrt</artifactId>
+ <version>1.9.??</version>
+</dependency>
+```
+
+Use the following [dependency matrix](https://github.com/eclipse-aspectj/aspectj/blob/master/docs/release/JavaVersionCompatibility.adoc) to understand which AspectJ version to use based on your JDK version:
+
+| JDK version | aspectj version |
+|-------------|------------------------|
+| `11-17` | `1.9.20.1` (or higher) |
+| `21` | `1.9.21` (or higher) |
+| `25` | `1.9.25` (or higher) |

+
+| Label | Usage | Notes |
+|----------------------------------|---------------------------------------------------------------------------------------------------|----------------------------------------------------|
+| triage | New issues that require maintainers review | Issue template |
+| bug | Unexpected, reproducible and unintended software behavior | PR/Release automation; Doc snippets are excluded; |

+
+## Maintainer Responsibilities
+
+Maintainers are active and visible members of the community, and have
+[maintain-level permissions on a repository](https://docs.github.com/en/organizations/managing-access-to-your-organizations-repositories/repository-permission-levels-for-an-organization){target="_blank"}.
+Use those privileges to serve the community and evolve code as follows.
+
+Be aware of recurring ambiguous situations and [document them](#common-scenarios) to help your fellow maintainers.
+
+### Uphold Code of Conduct
+
+<!-- markdownlint-disable-next-line MD013 -->
+Model the behavior set forward by the
+[Code of Conduct](https://github.com/aws-powertools/powertools-lambda-java/blob/main/CODE_OF_CONDUCT.md){target="_blank"}
+and raise any violations to other maintainers and admins. There could be unusual circumstances where inappropriate
+behavior does not immediately fall within the [Code of Conduct](https://github.com/aws-powertools/powertools-lambda-java/blob/main/CODE_OF_CONDUCT.md){target="_blank"}.
+
+These might be nuanced and should be handled with extra care - when in doubt, do not engage and reach out to other maintainers
+and admins.
+
+### Prioritize Security
+
+Security is your number one priority. Maintainer's Github keys must be password protected securely and any reported
+security vulnerabilities are addressed before features or bugs.
+
+Note that this repository is monitored and supported 24/7 by Amazon Security, see
+[Security disclosures](https://github.com/aws-powertools/powertools-lambda-java/){target="_blank"} for details.
+
+### Review Pull Requests
+
+Review pull requests regularly, comment, suggest, reject, merge and close. Accept only high quality pull-requests.
+Provide code reviews and guidance on incoming pull requests.
+
+PRs are [labeled](#labels) based on file changes and semantic title. Pay attention to whether labels reflect the current
+state of the PR and correct accordingly.
+
+Use and enforce [semantic versioning](https://semver.org/){target="_blank" rel="nofollow"} pull request titles, as these will be used for
+[CHANGELOG](https://github.com/aws-powertools/powertools-lambda-java/blob/main/CHANGELOG.md){target="_blank"}
+and [Release notes](https://github.com/aws-powertools/powertools-lambda-java/releases) - make sure they communicate their
+intent at the human level.
+
+For issues linked to a PR, make sure `status/staged-next-release` label is applied to them when merging.
+[Upon release](#releasing-a-new-version), these issues will be notified which release version contains their change.
+
+See [Common scenarios](#common-scenarios) section for additional guidance.
+
+### Triage New Issues
+
+Manage [labels](#labels), review issues regularly, and create new labels as needed by the project. Remove `triage`
+label when you're able to confirm the validity of a request, a bug can be reproduced, etc.
+Give priority to the original author for implementation, unless it is a sensitive task that is best handled by maintainers.
+
+Make sure issues are assigned to our [board of activities](https://github.com/orgs/aws-powertools/projects/4).
+
+Use our [labels](#labels) to signal good first issues to new community members, and to set expectation that this might
+need additional feedback from the author, other customers, experienced community members and/or maintainers.
+
+Be aware of [casual contributors](https://opensource.com/article/17/10/managing-casual-contributors){target="_blank" rel="nofollow"} and recurring contributors.
+Provide the experience and attention you wish you had if you were starting in open source.
+
+See [Common scenarios](#common-scenarios) section for additional guidance.
+
+### Triage Bug Reports
+
+Be familiar with [our definition of bug](#is-that-a-bug). If it's not a bug, you can close it or adjust its title and
+labels - always communicate the reason accordingly.
+
+For bugs caused by upstream dependencies, replace `bug` with `bug-upstream` label. Ask the author whether they'd like to
+raise the issue upstream or if they prefer us to do so.
+
+Assess the impact and make the call on whether we need an emergency release. Contact other [maintainers](#current-maintainers) when in doubt.
+
+See [Common scenarios](#common-scenarios) section for additional guidance.
+
+### Triage RFCs
+
+RFC is a collaborative process to help us get to the most optimal solution given the context. Their purpose is to ensure
+everyone understands what this context is, their trade-offs, and alternative solutions that were part of the research
+before implementation begins.
+
+Make sure you ask these questions in mind when reviewing:
+
+- Does it use our [RFC template](https://github.com/aws-powertools/powertools-lambda-java/issues/new?assignees=&labels=RFC%2C+triage&projects=&template=rfc.md&title=RFC%3A+)?
+- Does it match our [Tenets](https://docs.powertools.aws.dev/lambda/java/latest/#tenets)?
+- Does the proposal address the use case? If so, is the recommended usage explicit?
+- Does it focus on the mechanics to solve the use case over fine-grained implementation details?
+- Can anyone familiar with the code base implement it?
+- If approved, are they interested in contributing? Do they need any guidance?
+- Does this significantly increase the overall project maintenance? Do we have the skills to maintain it?
+- If we can't take this use case, are there alternative projects we could recommend? Or does it call for a new project altogether?
+
+When necessary, be upfront that the time to review, approve, and implement a RFC can vary -
+see [Contribution is stuck](#contribution-is-stuck). Some RFCs may be further updated after implementation, as certain areas become clearer.
+
+Some examples using our initial and new RFC templates: #92, #94, #95, #991, #1226
+
+### Releasing a new version
+
+!!! note "The release process is currently a long, multi-step process. The team is in the process of automating at it."
+
+Firstly, make sure the commit history in the `main` branch **(1)** it's up to date, **(2)** commit messages are semantic,
+and **(3)** commit messages have their respective area, for example `feat: <change>`, `chore: ...`).
+
+**Looks good, what's next?**
+
+Kickoff the `Prepare for maven central release` workflow with the intended rekease version. Once this has completed, it will
+draft a Pull Request named something like `chore: Prep release 1.19.0`. the PR will **(1)** roll all of the POM versions
+forward to the new release version and **(2)** release notes.
+
+Once this is done, check out the branch and clean up the release notes. These will be used both in the
+[CHANGELOG.md file](https://github.com/aws-powertools/powertools-lambda-java/blob/main/CHANGELOG.md)
+file and the [published github release information](https://github.com/aws-powertools/powertools-lambda-java/releases),
+and you can use the existing release notes to see how changes are summarized.
+
+Next, commit and push, wait for the build to complete, and merge to main. Once main has built successfully (i.e. build, tests and end-to-end tests should pass), create a
+tagged release from the Github UI, using the same release notes.
+
+Next, run the `Publish package to the Maven Central Repository` action to release the library.
+
+Finally, by hand, create a PR rolling all of the POMs onto the next snapshot version (e.g. `1.20.0-SNAPSHOT`).
+
+
+### Add Continuous Integration Checks
+
+Add integration checks that validate pull requests and pushes to ease the burden on Pull Request reviewers.
+Continuously revisit areas of improvement to reduce operational burden in all parties involved.
+
+### Negative Impact on the Project
+<!-- markdownlint-disable-next-line MD013 -->
+Actions that negatively impact the project will be handled by the admins, in coordination with other maintainers,
+in balance with the urgency of the issue. Examples would be
+[Code of Conduct](https://github.com/aws-powertools/powertools-lambda-java/blob/main/CODE_OF_CONDUCT.md){target="_blank"}
+violations, deliberate harmful or malicious actions, spam, monopolization, and security risks.
+
+## Common scenarios
+
+These are recurring ambiguous situations that new and existing maintainers may encounter. They serve as guidance.
+It is up to each maintainer to follow, adjust, or handle in a different manner as long as
+[our conduct is consistent](#uphold-code-of-conduct)
+
+### Contribution is stuck
+
+A contribution can get stuck often due to lack of bandwidth and language barrier. For bandwidth issues,
+check whether the author needs help. Make sure you get their permission before pushing code into their existing PR -
+do not create a new PR unless strictly necessary.
+
+For language barrier and others, offer a 1:1 chat to get them unblocked. Often times, English might not be their
+primary language, and writing in public might put them off, or come across not the way they intended to be.
+
+In other cases, you may have constrained capacity. Use `help wanted` label when you want to signal other maintainers
+and external contributors that you could use a hand to move it forward.
+
+### Insufficient feedback or information
+
+When in doubt, use the `need-more-information` label to signal more context and feedback are necessary before proceeding.
+
+### Crediting contributions
+
+We credit all contributions as part of each [release note](https://github.com/aws-powertools/powertools-lambda-java/releases){target="_blank"}
+as an automated process. If you find contributors are missing from the release note you're producing, please add them manually.
+
+### Is that a bug?
+
+A bug produces incorrect or unexpected results at runtime that differ from its intended behavior.
+Bugs must be reproducible. They directly affect customers experience at runtime despite following its recommended usage.
+
+Documentation snippets, use of internal components, or unadvertised functionalities are not considered bugs.
+
+### Mentoring contributions
+
+Always favor mentoring issue authors to contribute, unless they're not interested or the implementation is sensitive (_e.g., complexity, time to release, etc._).
+
+Make use of `help wanted` and `good first issue` to signal additional contributions the community can help.
+
+### Long running issues or PRs
+
+Try offering a 1:1 call in the attempt to get to a mutual understanding and clarify areas that maintainers could help.
+
+In the rare cases where both parties don't have the bandwidth or expertise to continue, it's best to use the `revisit-in-3-months` label. By then, see if it's possible to break the PR or issue in smaller chunks, and eventually close if there is no progress.

+title: Versioning and maintenance policy
+description: Versioning and maintenance policy for Powertools for AWS Lambda (Python)
+---
+
+### Overview
+
+This document outlines the maintenance policy for Powertools for AWS Lambda and their underlying dependencies. AWS regularly provides Powertools for AWS Lambda with updates that may contain new features, enhancements, bug fixes, security patches, or documentation updates. Updates may also address changes with dependencies, language runtimes, and operating systems. Powertools for AWS Lambda is published to package managers (e.g. PyPi, NPM, Maven, NuGet), and are available as source code on GitHub.
+
+We recommend users to stay up-to-date with Powertools for AWS Lambda releases to keep up with the latest features, security updates, and underlying dependencies. Continued use of an unsupported Powertools for AWS Lambda version is not recommended and is done at the user’s discretion.
+
+!!! info "For brevity, we will interchangeably refer to Powertools for AWS Lambda as "SDK" _(Software Development Toolkit)_."
+
+### Versioning
+
+Powertools for AWS Lambda release versions are in the form of X.Y.Z where X represents the major version. Increasing the major version of an SDK indicates that this SDK underwent significant and substantial changes to support new idioms and patterns in the language. Major versions are introduced when public interfaces _(e.g. classes, methods, types, etc.)_, behaviors, or semantics have changed. Applications need to be updated in order for them to work with the newest SDK version. It is important to update major versions carefully and in accordance with the upgrade guidelines provided by AWS.
+
+### SDK major version lifecycle
+
+The lifecycle for major Powertools for AWS Lambda versions consists of 5 phases, which are outlined below.
+
+- **Developer Preview** (Phase 0) - During this phase, SDKs are not supported, should not be used in production environments, and are meant for early access and feedback purposes only. It is possible for future releases to introduce breaking changes. Once AWS identifies a release to be a stable product, it may mark it as a Release Candidate. Release Candidates are ready for GA release unless significant bugs emerge, and will receive full AWS support.
+- **General Availability (GA)** (Phase 1) - During this phase, SDKs are fully supported. AWS will provide regular SDK releases that include support for new features, enhancements, as well as bug and security fixes. AWS will support the GA version of an SDK for _at least 24 months_, unless otherwise specified.
+- **Maintenance Announcement** (Phase 2) - AWS will make a public announcement at least 6 months before an SDK enters maintenance mode. During this period, the SDK will continue to be fully supported. Typically, maintenance mode is announced at the same time as the next major version is transitioned to GA.
+- **Maintenance** (Phase 3) - During the maintenance mode, AWS limits SDK releases to address critical bug fixes and security issues only. An SDK will not receive API updates for new or existing services, or be updated to support new regions. Maintenance mode has a _default duration of 6 months_, unless otherwise specified.
+- **End-of-Support** (Phase 4) - When an SDK reaches end-of support, it will no longer receive updates or releases. Previously published releases will continue to be available via public package managers and the code will remain on GitHub. The GitHub repository may be archived. Use of an SDK which has reached end-of-support is done at the user’s discretion. We recommend users upgrade to the new major version.
+
+!!! note "Please note that the timelines shown below are illustrative and not binding"
+
+
+
+### Dependency lifecycle
+
+Most AWS SDKs have underlying dependencies, such as language runtimes, AWS Lambda runtime, or third party libraries and frameworks. These dependencies are typically tied to the language community or the vendor who owns that particular component. Each community or vendor publishes their own end-of-support schedule for their product.
+
+The following terms are used to classify underlying third party dependencies:
+
+- [**AWS Lambda Runtime**](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html): Examples include `java17`, `nodejs20.x`, `python3.13`, etc.
+- **Language Runtime**: Examples include Java 17, Python 3.13, NodeJS 20, .NET Core, etc.
+- **Third party Library**: Examples include Jackson Project, AWS X-Ray SDK, AWS Encryption SDK, etc.
+
+Powertools for AWS Lambda follows the [AWS Lambda Runtime deprecation policy cycle](https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html#runtime-support-policy), when it comes to Language Runtime. This means we will stop supporting their respective deprecated Language Runtime _(e.g., `java8`)_ without increasing the major SDK version.
+
+!!! note "AWS reserves the right to stop support for an underlying dependency without increasing the major SDK version"
+
+### Communication methods
+
+Maintenance announcements are communicated in several ways:
+
+- A pinned GitHub Request For Comments (RFC) issue indicating the campaign for the next major version. The RFC will outline the path to end-of-support, specify campaign timelines, and upgrade guidance.
+- AWS SDK documentation, such as API reference documentation, user guides, SDK product marketing pages, and GitHub readme(s) are updated to indicate the campaign timeline and provide guidance on upgrading affected applications.
+- Deprecation warnings are added to the SDKs, outlining the path to end-of-support and linking to the upgrade guide.

+title: Roadmap
+description: Public roadmap for Powertools for AWS Lambda (Java)
+---
+
+## Overview
+
+Our public roadmap outlines the high level direction we are working towards. We update this document when our priorities change: security and stability are our top priority.
+
+### Key areas
+
+Security and operational excellence take precedence above all else. This means bug fixing, stability, customer's support, and internal compliance may delay one or more key areas below.
+
+!!! info "We may choose to re-prioritize or defer items based on customer feedback, security, and operational impacts, and business value."
+
+#### Release Security (p0)
+
+Our top priority is to establish the processes and infrastructure needed for a fully automated and secure end-to-end release process of new versions to Maven Central.
+
+- [x] [Implement GitHub workflows](https://github.com/aws-powertools/powertools-lambda-java/issues/1231){target="\_blank"} and create infrastructure to release to Maven Central
+- [x] [Implement end-to-end tests](https://github.com/aws-powertools/powertools-lambda-java/issues/1815){target="\_blank"}
+- [x] Implement [OpenSSF Scorecard](https://openssf.org/projects/scorecard/){target="\_blank"}
+
+#### `v2` Release: Consistency and Ecosystem (p1)
+
+As part of a new major version `v2` release, we prioritize the Java project's consistency of core utilities (Logging, Metrics, Tracing) with the other runtimes (Python, TypeScript, .NET). Additionally, we will focus on integrating the library with popular technologies and frameworks from the Java and AWS ecosystem. Particularly, we aim at leveraging new techniques to allow customers to reduce Lambda cold-start time. The `v2` release will also drop support for Java 8 moving to Java 11 as the baseline.
+
+##### Core Utilities
+
+- [x] [Review public interfaces and reduce public API surface area](https://github.com/aws-powertools/powertools-lambda-java/issues/1283){target="\_blank"}
+- [x] [Release Logging `v2` module](https://github.com/aws-powertools/powertools-lambda-java/issues/965){target="\_blank"} allowing customers to choose the logging framework and adding support for logging deeply nested objects as JSON
+- [x] [Support high resolution metrics](https://github.com/aws-powertools/powertools-lambda-java/issues/1041){target="\_blank"}
+- [x] [Improve modularity of metrics module](https://github.com/aws-powertools/powertools-lambda-java/issues/1848){target="\_blank"} to remove coupling with EMF library and enable future support for additional metrics providers / backends
+
+##### Ecosystem
+
+- [x] [Add GraalVM support for core utilities](https://github.com/aws-powertools/powertools-lambda-java/issues/764){target="\_blank"}
+- [ ] [Implement priming using CRaC to improve AWS Snapstart support](https://github.com/aws-powertools/powertools-lambda-java/issues/1588){target="\_blank"}
+- [ ] [Evaluate integration with popular Java frameworks such as Micronaut, Spring Cloud Function, or Quarkus](https://github.com/aws-powertools/powertools-lambda-java/issues/1701){target="\_blank"}
+
+##### Other
+
+- [x] [Validation module integration with HTTP requests](https://github.com/aws-powertools/powertools-lambda-java/issues/1298){target="\_blank"}
+- [x] [Support validation module from within the batch module](https://github.com/aws-powertools/powertools-lambda-java/issues/1496){target="\_blank"}
+- [x] [Add support for parallel processing in Batch Processing utility](https://github.com/aws-powertools/powertools-lambda-java/issues/1540){target="\_blank"}
+- [ ] [Documentation: Review and improve documentation to be consistent with other runtimes](https://github.com/aws-powertools/powertools-lambda-java/issues/1352){target="\_blank"}
+
+#### Feature Parity (p2)
+
+If priorities `p0` and `p1` are addressed, we will also focus on feature parity of non-core utilities. This allows customers to achieve better standardization of their development processes across different Powertools runtimes.
+
+- [ ] [Re-evaluate if there is a need for adding a lightweight customer Powertools event handler](https://github.com/aws-powertools/powertools-lambda-java/issues/1103){target="\_blank"}
+- [ ] [Add comprehensive GraalVM support for all utilities](){target="\_blank"}
+- [ ] [Add Feature Flags module](https://github.com/aws-powertools/powertools-lambda-java/issues/1086){target="\_blank"}
+- [ ] [Add S3 Streaming module](https://github.com/aws-powertools/powertools-lambda-java/issues/1085){target="\_blank"}
+- [ ] Add support for Data Masking during JSON serialization
+
+### Missing something?
+
+You can help us prioritize by [upvoting existing feature requests](https://github.com/aws-powertools/powertools-lambda-java/issues?q=is%3Aissue%20state%3Aopen%20label%3Aenhancement){target="\_blank"},
+leaving a comment on what use cases it could unblock for you, and by joining our discussions on Discord.

+
+Our end-to-end mechanism follows four major steps:
+
+- **Feature Request**. Ideas start with a [feature request](https://github.com/aws-powertools/powertools-lambda-java/issues/new?template=feature_request.md){target="\_blank"} to outline their use case at a high level. For complex use cases, maintainers might ask for/write a
+ RFC.
+ - Maintainers review requests based on [project tenets](index.md#tenets){target="\_blank"}, customers reaction (👍),
+ and use cases.
+- **Request-for-comments (RFC)**. Design proposals use
+ our [RFC template](https://github.com/aws-powertools/powertools-lambda-java/issues/new?q=is%3Aissue+state%3Aopen+label%3Aenhancement&template=rfc.md){target="\_blank"} to describe its implementation, challenges, developer experience, dependencies, and alternative solutions.
+ - This helps refine the initial idea with community feedback before a decision is made.
+- **Decision**. After carefully reviewing and discussing them, maintainers make a final decision on whether to start
+ implementation, defer or reject it, and update everyone with the next steps.
+- **Implementation**. For approved features, maintainers give priority to the original authors for implementation unless
+ it is a sensitive task that is best handled by maintainers.
+
+!!! info "See [Maintainers](./processes/maintainers.md){target="\_blank"} document to understand how we triage issues and pull requests, labels and governance."
+
+### Disclaimer
+
+The Powertools for AWS Lambda (Java) team values feedback and guidance from its community of users, although final
+decisions on inclusion into the project will be made by AWS.
+
+We determine the high-level direction for our open roadmap based on customer feedback and popularity (👍🏽 and comments),
+security and operational impacts, and business value. Where features don’t meet our goals and longer-term strategy, we
+will communicate that clearly and openly as quickly as possible with an explanation of why the decision was made.
+
+### FAQs
+
+**Q: Why did you build this?**
+
+A: We know that our customers are making decisions and plans based on what we are developing, and we want to provide our
+customers the insights they need to plan.
+
+**Q: Why are there no dates on your roadmap?**
+
+A: Because job zero is security and operational stability, we can't provide specific target dates for features. The
+roadmap is subject to change at any time, and roadmap issues in this repository do not guarantee a feature will be
+launched as proposed.
+
+**Q: How can I provide feedback or ask for more information?**
+
+A: For existing features, you can directly comment on issues. For anything else, please open an issue.

+title: Upgrade guide
+description: Guide to update between major Powertools for AWS Lambda (Java) versions
+---
+
+## End of support v1
+
+<!-- prettier-ignore-start -->
+!!! warning "End of support notice"
+ On December 12th, 2025, Powertools for AWS Lambda (Java) v1 reached end-of-life and will no longer receive updates or releases. If you are still using v1, we strongly recommend you to read our upgrade guide and update to the latest version. Refer to [our announcement](https://github.com/aws-powertools/powertools-lambda-java/issues/1895) for details.
+<!-- prettier-ignore-end -->
+
+Given our commitment to all of our customers using Powertools for AWS Lambda (Java), we will keep [Maven Central](https://central.sonatype.com/search?q=powertools){target="\_blank"} `v1` releases and a `v1` documentation archive to prevent any disruption.
+
+## Migrate to v2 from v1
+
+!!! info "We strongly encourage you to migrate to `v2`. Refer to our [versioning policy](./processes/versioning.md) to learn more about our version support process."
+
+We've made minimal breaking changes to make your transition to `v2` as smooth as possible.
+
+### Quick summary
+
+The following table shows a summary of the changes made in `v2` and whether code changes are necessary. Each change that requires a code change links to a section below explaining more details.
+
+| Area | Change | Code change required |
+| -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------- |
+| **Logging** | The [logging module was re-designed](#redesigned-logging-utility) from scratch to support popular Java logging paradigms and libraries like `log4j2`, `logback`, and `slf4j`. | Yes |
+| **Metrics** | [Changed public interface](#updated-metrics-utility-interface) to remove direct coupling with `aws-embedded-metrics-java`. | Yes |
+| **Tracing** | [Removed deprecated `captureResponse` and `captureError` options](#deprecated-capture-mode-related-tracing-annotation-parameters) on `@Tracing` annotation. | Yes |

+
+### First Steps
+
+Before you start, we suggest making a copy of your current working project or create a new branch with `git`.
+
+1. **Upgrade** Java to at least version 11. While version 11 is supported, we recommend using the [newest available LTS version](https://downloads.corretto.aws/#/downloads){target="\_blank"} of Java.
+2. **Review** the following section to confirm if you need to make changes to your code.
+
+## Redesigned Logging Utility
+
+<!--
+- Add new logging module: https://github.com/aws-powertools/powertools-lambda-java/pull/1539
+- Add advanced features to new logging module: https://github.com/aws-powertools/powertools-lambda-java/pull/1435
+- Block reserved keys: https://github.com/aws-powertools/powertools-lambda-java/commit/374b38db3b91d421a14bb71b4df0194c72304efa
+-->
+
+The logging utility was re-designed from scratch to integrate better with Java idiomatic conventions and to remove the hard dependency on `log4j` as logging implementation. The new logging utility now supports `slfj4` as logging interface and gives you the choice among `log4j2` and `logback` as logging implementations. Consider the following steps to migrate from the v1 logging utility to the v2 logging utility:
+
+**1. Remove `powertools-logging` dependency and replace it with your logging backend of choice**
+
+In order to support different logging implementations, dedicated logging modules were created for the different logging implementations. Remove `powertools-logging` as a dependency and replace it with either `powertools-logging-log4j` or `powertools-logging-logback`.
+
+```diff
+<!-- BEFORE v2 -->
+- <dependency>
+- <groupId>software.amazon.lambda</groupId>
+- <artifactId>powertools-logging</artifactId>
+- <version>1.x.x</version>
+- </dependency>
+
+<!-- AFTER v2 -->
++ <dependency>
++ <groupId>software.amazon.lambda</groupId>
++ <artifactId>powertools-logging-log4j</artifactId>
++ <version>2.x.x</version>
++ </dependency>
+```
+
+<!-- prettier-ignore-start -->
+!!! info "The AspectJ configuration still needs to depend on `powertools-logging`"
+ We have only replaced the logging implementation dependency. The AspectJ configuration still needs to depend on `powertools-logging` which contains the main logic.
+
+ ```xml
+ <aspectLibrary>
+ <groupId>software.amazon.lambda</groupId>
+ <artifactId>powertools-logging</artifactId>
+ </aspectLibrary>
+ ```
+<!-- prettier-ignore-end -->
+
+**2. Update `log4j2.xml` including new `JsonTemplateLayout`**
+
+This step is only required if you are using log4j2 as your logging implementation. The deprecated `#!xml <LambdaJsonLayout/>` element was removed. Replace it with the log4j2 agnostic `#!xml <JsonTemplateLayout/>` element.
+
+```diff
+<?xml version="1.0" encoding="UTF-8"?>
+<Configuration>
+ <Appenders>
+ <Console name="JsonAppender" target="SYSTEM_OUT">
+- <LambdaJsonLayout compact="true" eventEol="true"/>
++ <JsonTemplateLayout eventTemplateUri="classpath:LambdaJsonLayout.json" />
+ </Console>
+ </Appenders>
+ <Loggers>
+ <Logger name="JsonLogger" level="INFO" additivity="false">
+ <AppenderRef ref="JsonAppender"/>
+ </Logger>
+ <Root level="info">
+ <AppenderRef ref="JsonAppender"/>
+ </Root>
+ </Loggers>
+</Configuration>
+```
+
+**3. Migrate all logging specific calls to SLF4J native primitives (recommended)**
+
+The new logging utility is designed to integrate seamlessly with Java SLF4J to allow customers adopt the Logging utility without large code refactorings. This improvement requires the migration of non-native SLF4J primitives from the v1 Logging utility.
+
+!!! info "While we recommend using SLF4J as a logging implementation independent facade, you can still use the log4j2 and logback interfaces directly."
+
+Consider the following code example which gives you hints on how to achieve the same functionality between v1 and v2 Logging:
+
+```diff
+import org.slf4j.Logger;
+import org.slf4j.LoggerFactory;
+import software.amazon.lambda.powertools.logging.Logging;
+// ... other imports
+
+public class PaymentFunction implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+ // BEFORE v2: Uses org.apache.logging.log4j.LogManager
+- private static final Logger LOGGER = LogManager.getLogger(PaymentFunction.class);
+ // AFTER v2: Use org.slf4j.LoggerFactory
++ private static final Logger LOGGER = LoggerFactory.getLogger(PaymentFunction.class);
+
+ @Logging
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent input, final Context context) {
+ // ...
+
+ // BEFORE v2: Uses LoggingUtils.appendKey to append custom global keys
+ // LoggingUtils was removed!
+- LoggingUtils.appendKey("cardNumber", card.getId());
+ // AFTER v2: Uses native SLF4J Mapped Diagnostic Context (MDC)
++ MDC.put("cardNumber", card.getId());
+
+ // Regular logging has not changed
+ LOGGER.info("My log message with argument.");
+
+ // Adding custom keys on a specific log message
+ // BEFORE v2: No direct way, only supported via LoggingUtils.appendKey and LoggingUtils.removeKey
+ // AFTER v2: Extensive support for StructuredArguments
++ LOGGER.info("Collecting payment", StructuredArguments.entry("orderId", order.getId()));
+ // { "message": "Collecting payment", ..., "orderId": 123}
+ Map<String, String> customKeys = new HashMap<>();
+ customKeys.put("paymentId", payment.getId());
+ customKeys.put("amount", payment.getAmount);
++ LOGGER.info("Payment successful", StructuredArguments.entries(customKeys));
+ // { "message": "Payment successful", ..., "paymentId": 123, "amount": 12.99}
+ }
+}
+```
+
+!!! info "Make sure to learn more about the advanced structured argument serialization features in the [Logging v2 documentation](./core/logging.md/#custom-keys)."
+
+## Updated Metrics utility interface
+
+<!-- - Remove deprecated methods: https://github.com/aws-powertools/powertools-lambda-java/pull/1624/files#diff-0afede8005aa2baeba2770f66d611bf0e8ee3969205be27e803682a7f2d6520a -->
+<!-- - Re-designed metrics module: https://github.com/aws-powertools/powertools-lambda-java/issues/1848 -->
+
+The Metrics utility was redesigned to be more modular and allow for the addition of new metrics providers in the future. The same EMF-based metrics logging still applies but will be called via an updated public interface. Consider the following list to understand some of changes:
+
+- `#!java @Metrics` was renamed to `#!java @FlushMetrics`
+- `#!java MetricsLogger.metricsLogger()` was renamed to `#!java MetricsFactory.getMetricsInstance()`
+- `put*` calls such as `#!java putMetric()` where replaced with `add*` nomenclature such as `#!java addMetric()`
+- All direct imports from `software.amazon.cloudwatchlogs.emf` need to be replaced with Powertools counterparts from `software.amazon.lambda.powertools.metrics` (see example below)
+- The `withSingleMetric` and `withMetricsLogger` methods were removed in favor of `#!java metrics.flushSingleMetric()`
+- It is no longer valid to skip declaration of a namespace. If no namespace is provided, an exception will be raised instead of using the default `aws-embedded-metrics` namespace.
+
+The following example shows a common Lambda handler using the Metrics utility and required refactorings.
+
+```diff
+// Metrics is not a decorator anymore but the replacement for the `MetricsLogger` Singleton
+import software.amazon.lambda.powertools.metrics.Metrics;
++ import software.amazon.lambda.powertools.metrics.FlushMetrics;
+- import software.amazon.lambda.powertools.metrics.MetricsUtils;
++ import software.amazon.lambda.powertools.metrics.MetricsFactory;
+- import software.amazon.cloudwatchlogs.emf.logger.MetricsLogger;
+- import software.amazon.cloudwatchlogs.emf.model.DimensionSet;
+- import software.amazon.cloudwatchlogs.emf.model.Unit;
++ import software.amazon.lambda.powertools.metrics.model.DimensionSet;
++ import software.amazon.lambda.powertools.metrics.model.MetricUnit;
+
+public class MetricsEnabledHandler implements RequestHandler<Object, Object> {
+
+ // This is still a Singleton
+- MetricsLogger metricsLogger = MetricsUtils.metricsLogger();
++ Metrics metrics = MetricsFactory.getMetricsInstance();
+
+ @Override
+- @Metrics(namespace = "ExampleApplication", service = "booking")
++ @FlushMetrics(namespace = "ExampleApplication", service = "booking")
+ public Object handleRequest(Object input, Context context) {
+- metricsLogger.putDimensions(DimensionSet.of("environment", "prod"));
++ metrics.addDimension(DimensionSet.of("environment", "prod"));
+ // New method overload for adding 2D dimensions more conveniently
++ metrics.addDimension("environment", "prod");
+- metricsLogger.putMetric("SuccessfulBooking", 1, Unit.COUNT);
++ metrics.addMetric("SuccessfulBooking", 1, MetricUnit.COUNT);
+ ...
+ }
+}
+```
+
+Learn more about the redesigned Metrics utility in the [Metrics documentation](./core/metrics.md).
+
+## Deprecated capture mode related `@Tracing` annotation parameters
+
+<!-- - Remove deprecated methods: https://github.com/aws-powertools/powertools-lambda-java/pull/1624/files#diff-9b8ed4ca67e310d3ae90e61e2ceffbfec0402082b5a1f741d467f132e3370a21 -->
+
+The deprecated `captureError` and `captureResponse` arguments to the `@Tracing` annotation were removed in v2 and replaced by a new `captureMode` parameter. The parameter can be passed an Enum value of `CaptureMode`.
+
+You should update your code using the new `captureMode` argument:
+
+```diff
+- @Tracing(captureError = false, captureResponse = false)
++ @Tracing(captureMode = CaptureMode.DISABLED)
+public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ // ...
+}
+```
+
+Learn more about valid `CaptureMode` values in the [Tracing documentation](./core/tracing.md).
+
+## Idempotency utility split into sub-modules by provider
+
+The Idempotency utility was split from the common `powertools-idempotency` package into individual packages for different persistence store providers. The main business logic is now in the `powertools-idempotency-core` package.
+
+You should now include the `powertools-idempotency-core` package as an AspectJ library and the provider package like `powertools-idempotency-dynamodb` as a regular dependency.
+
+```diff
+<!-- BEFORE v2 -->
+- <dependency>
+- <groupId>software.amazon.lambda</groupId>
+- <artifactId>powertools-idempotency</artifactId>
+- <version>1.x.x</version>
+- </dependency>
+<!-- AFTER v2 -->
+<!-- In dependencies section -->
++ <dependency>
++ <groupId>software.amazon.lambda</groupId>
++ <artifactId>powertools-idempotency-dynamodb</artifactId>
++ <version>2.x.x</version>
++ </dependency>
+<!-- In AspectJ configuration section -->
++ <aspectLibrary>
++ <groupId>software.amazon.lambda</groupId>
++ <artifactId>powertools-idempotency-core</artifactId>
++ </aspectLibrary>
+```
+
+## Parameters utility split into sub-modules by provider
+
+Parameters utilities were split from the common `powertools-parameters` package into individual packages for different parameter providers. You should now include the specific parameters dependency for your provider. If you use multiple providers, you can include multiple packages. Each parameter provider needs to be included as a dependency and an AspectJ library to use annotations.
+
+This new structure reduces the bundle size of your deployment package.
+
+```diff
+<!-- BEFORE v2 -->
+<!-- In dependencies section -->
+- <dependency>
+- <groupId>software.amazon.lambda</groupId>
+- <artifactId>powertools-parameters</artifactId>

+<!-- - Remove deprecated methods: https://github.com/aws-powertools/powertools-lambda-java/pull/1624/files#diff-0afede8005aa2baeba2770f66d611bf0e8ee3969205be27e803682a7f2d6520a -->
+
+The `Response` class supporting CloudFormation Custom Resource implementations was updated to remove deprecated methods.
+
+The `#!java Response.failed()` and `#!java Response.success()` methods without parameters were removed and require the physical resource ID now. You should update your code to use:
+
+- `#!java Response.failed(String physicalResourceId)`
+- `#!java Response.success(String physicalResourceId)`
+
+```diff
+import com.amazonaws.services.lambda.runtime.Context;
+import com.amazonaws.services.lambda.runtime.events.CloudFormationCustomResourceEvent;
+import software.amazon.lambda.powertools.cloudformation.AbstractCustomResourceHandler;
+import software.amazon.lambda.powertools.cloudformation.Response;
+
+public class MyCustomResourceHandler extends AbstractCustomResourceHandler {
+
+ // ...
+
+ @Override
+ protected Response update(CloudFormationCustomResourceEvent updateEvent, Context context) {
++ String physicalResourceId = updateEvent.getPhysicalResourceId();
+ UpdateResult updateResult = doUpdates(physicalResourceId);
+ if (updateResult.isSuccessful()) {
+- return Response.success();
++ return Response.success(physicalResourceId);
+ } else {
+- return Response.failed();
++ return Response.failed(physicalResourceId);
+ }
+ }
+
+ // ...
+}
+```
+
+## Improved integration of Validation utility with other utilities
+
+<!--
+- Partial failure batch validation: https://github.com/aws-powertools/powertools-lambda-java/pull/1621
+- Return 4xx errors codes with API GW: https://github.com/aws-powertools/powertools-lambda-java/pull/1489
+-->
+
+The Validation utility includes two updates that change the behavior of integration with other utilities and AWS services.
+
+**1. Updated HTTP status code when using `@Validation` with API Gateway**
+
+This does not require a code change in the Lambda function using the Validation utility but might impact how your calling application treats exceptions. Prior to `v2`, a 500 HTTP status code was returned when the validation did not pass. Consistent with the [HTTP specification](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Status){target="\_blank"}, a 400 status code is returned now indicating a user error instead of a server error.
+
+Consider the following example:
+
+```java
+import software.amazon.lambda.powertools.validation.Validation;
+
+public class MyFunctionHandler implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ @Override
+ @Validation(inboundSchema = "classpath:/schema_in.json", outboundSchema = "classpath:/schema_out.json")
+ public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ // ...
+ return something;
+ }
+}
+```
+
+If the request validation fails, you can expect the following change in the HTTP response status code on the client-side:
+
+```sh
+# BEFORE v2: 500 Internal Server Error
+❯ curl -s -o /dev/null -w "%{http_code}" https://{API_ID}.execute-api.{REGION}.amazonaws.com/{STAGE}/{PATH}
+500
+# AFTER v2: 400 Bad Request
+❯ curl -s -o /dev/null -w "%{http_code}" https://{API_ID}.execute-api.{REGION}.amazonaws.com/{STAGE}/{PATH}
+400
+```
+
+**2. Integration with partial batch failures when using Batch utility**
+
+This does not require a code change but might affect the batch processing flow when using the Validation utility in combination with the Batch processing utility.
+
+Consider the following example:
+
+```java
+import com.amazonaws.services.lambda.runtime.Context;
+import com.amazonaws.services.lambda.runtime.RequestHandler;
+import com.amazonaws.services.lambda.runtime.events.SQSBatchResponse;
+import com.amazonaws.services.lambda.runtime.events.SQSEvent;
+import software.amazon.lambda.powertools.batch.BatchMessageHandlerBuilder;
+import software.amazon.lambda.powertools.batch.handler.BatchMessageHandler;
+
+public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ private final BatchMessageHandler<SQSEvent, SQSBatchResponse> handler;
+
+ public SqsBatchHandler() {
+ handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWithMessageHandler(this::processMessage, Product.class);
+ }
+
+ @Override
+ @Validation(inboundSchema = "classpath:/schema_in.json", outboundSchema = "classpath:/schema_out.json")
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ return handler.processBatch(sqsEvent, context);
+ }
+
+ private void processMessage(Product p, Context c) {
+ // Process the product
+ }
+}
+```
+
+- **Prior to `v2`** this caused the whole batch to fail.
+- **After `v2`** this will add only the failed events to the batch item failure list in the response and process the remaining messages.
+
+!!! info "Check if your workload can tolerate this behavior and make sure it is designed for idempotency when using partial batch item failures. We offer the [Idempotency](./utilities/idempotency.md) utility to simplify integration of idempotent behavior in your workloads."
+
+## AspectJ runtime not included by default anymore
+
+The AspectJ runtime is no longer included as a transitive dependency of Powertools. For all utilities offering annotations using AspectJ compile-time weaving, you need to include the AspectJ runtime yourself now. This is also documented, with a complete example, in our [installation guide](./index.md). For Maven projects, make sure to add the following dependency in your dependencies section:
+
+```diff
++ <dependency>
++ <groupId>org.aspectj</groupId>
++ <artifactId>aspectjrt</artifactId>
++ <version>1.9.22</version>
++ </dependency>
+```
+
+## Removed `powertools-sqs` module in favor of `powertools-batch`
+
+The archived documentation contains a migration guide for both large message handling using `powertools-sqs` and batch processing using `powertools-sqs`. The sections below explain the high-level steps for your convenience.
+
+### Migrating SQS Batch processing (`@SqsBatch`)
+
+The [batch processing library](./utilities/batch.md) provides a way to process messages and gracefully handle partial failures for SQS, Kinesis Streams, and DynamoDB Streams batch sources. In comparison to the legacy SQS Batch library, it relies on [Lambda partial batch responses](https://docs.aws.amazon.com/lambda/latest/dg/services-sqs-errorhandling.html#services-sqs-batchfailurereporting){target="\_blank"}, which allows the library to provide a simpler, more reliable interface for processing batches.
+
+In order to get started, check out the new [processing messages from SQS](./utilities/batch.md/#processing-messages-from-sqs) documentation. In most cases, you will simply be able to retain your existing batch message handler function, and wrap it with the new batch processing interface. Unlike the `powertools-sqs` module, the new `powertools-batch` module uses _partial batch responses_ to communicate to Lambda which messages have been processed and must be removed from the queue. The return value of the handler's process function must be returned to Lambda.
+
+The new library also no longer requires the `SQS:DeleteMessage` action on the Lambda function's role policy, as Lambda
+itself now manages removal of messages from the queue.
+
+<!-- prettier-ignore-start -->
+!!! info "Some tuneables from `powertools-sqs` are no longer provided."
+ - **Non-retryable Exceptions** - there is no mechanism to indicate in a partial batch response that a particular message
+ should not be retried and instead moved to DLQ - a message either succeeds, or fails and is retried. A message
+ will be moved to the DLQ once the normal retry process has expired.
+ - **Suppress Exception** - The new batch processor does not throw an exception on failure of a handler. Instead,
+ its result must be returned by your code from your message handler to Lambda, so that Lambda can manage
+ the completed messages and retry behaviour.
+<!-- prettier-ignore-end -->
+
+### Migrating SQS Large message handling (`@SqsLargeMessage`)
+
+- Replace the dependency in Maven / Gradle: `powertools-sqs` ==> `powertools-large-messages`
+- Replace the annotation: `@SqsLargeMessage` ==> `@LargeMessage` (the new module handles both SQS and SNS)
+- Move the annotation away from the Lambda `handleRequest` method and put it on a method with `SQSEvent.SQSMessage` or `SNSEvent.SNSRecord` as first parameter.
+- The annotation now handles a single message, contrary to the previous version that was handling the complete batch. This gives more control, especially when dealing with partial failures with SQS (see the batch module).
+- The new module only provides an annotation: an equivalent to the `SqsUtils` class is not available anymore in this new version.

+title: Usage patterns
+description: Getting to know the Powertools for AWS Lambda toolkit
+---
+
+<!-- markdownlint-disable MD043 -->
+
+Powertools for AWS Lambda (Java) is a collection of utilities designed to help you build serverless applications on AWS.
+
+The toolkit is modular, so you can pick and choose the utilities you need for your application, but also combine them for a complete solution for your serverless applications.
+
+## Patterns
+
+Many of the utilities provided can be used with different patterns, depending on your preferences and the structure of your code.
+
+### AspectJ Annotation
+
+If you prefer using annotations to apply cross-cutting concerns to your Lambda handlers, the AspectJ annotation pattern is a good fit. This approach lets you decorate methods with Powertools utilities using annotations, applying their functionality with minimal code changes.
+
+This pattern works well when you want to keep your business logic clean and separate concerns using aspect-oriented programming.
+
+<!-- prettier-ignore -->
+!!! note
+ This approach requires configuring AspectJ compile-time weaving in your build tool (Maven or Gradle). See the [installation guide](./index.md#install) for setup instructions.
+
+=== "Logging"
+
+ ```java
+ import com.amazonaws.services.lambda.runtime.Context;
+ import com.amazonaws.services.lambda.runtime.RequestHandler;
+ import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyRequestEvent;
+ import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyResponseEvent;
+ import org.slf4j.Logger;
+ import org.slf4j.LoggerFactory;
+ import software.amazon.lambda.powertools.logging.CorrelationIdPaths;
+ import software.amazon.lambda.powertools.logging.Logging;
+
+ public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+ private static final Logger log = LoggerFactory.getLogger(App.class);
+
+ @Logging(logEvent = true, correlationIdPath = CorrelationIdPaths.API_GATEWAY_REST)
+ public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ log.info("Processing request");
+ return new APIGatewayProxyResponseEvent().withStatusCode(200).withBody("Success");
+ }
+ }
+ ```
+
+=== "Metrics"
+
+ ```java
+ import com.amazonaws.services.lambda.runtime.Context;
+ import com.amazonaws.services.lambda.runtime.RequestHandler;
+ import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyRequestEvent;

+ import software.amazon.lambda.powertools.metrics.Metrics;
+ import software.amazon.lambda.powertools.metrics.MetricsFactory;
+ import software.amazon.lambda.powertools.metrics.model.MetricUnit;
+
+ public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+ private static final Metrics metrics = MetricsFactory.getMetricsInstance();
+
+ @FlushMetrics(namespace = "ServerlessApp", service = "payment")
+ public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ metrics.addMetric("SuccessfulBooking", 1, MetricUnit.COUNT);
+ return new APIGatewayProxyResponseEvent().withStatusCode(200).withBody("Success");
+ }
+ }
+ ```
+
+=== "Tracing"
+
+ ```java
+ import com.amazonaws.services.lambda.runtime.Context;
+ import com.amazonaws.services.lambda.runtime.RequestHandler;
+ import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyRequestEvent;
+ import com.amazonaws.services.lambda.runtime.events.APIGatewayProxyResponseEvent;
+ import software.amazon.lambda.powertools.tracing.Tracing;
+ import software.amazon.lambda.powertools.tracing.TracingUtils;
+
+ public class App implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ @Tracing
+ public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ TracingUtils.putAnnotation("operation", "payment");
+ return processPayment();
+ }
+
+ @Tracing
+ private APIGatewayProxyResponseEvent processPayment() {
+ return new APIGatewayProxyResponseEvent().withStatusCode(200).withBody("Success");
+ }
+ }
+ ```
+
+### Functional Approach
+
+If you prefer a more functional programming style or want to avoid AspectJ configuration, you can use the Powertools for AWS Lambda (Java) utilities directly in your code. This approach is more explicit and provides full control over how the utilities are applied.
+
+This pattern is ideal when you want to avoid AspectJ setup or prefer a more imperative style. It also eliminates the AspectJ runtime dependency, making your deployment package more lightweight.

description: Utility

-The SQS batch processing utility provides a way to handle partial failures when processing batches of messages from SQS.
+The batch processing utility provides a way to handle partial failures when processing batches of messages from SQS queues,
+SQS FIFO queues, Kinesis Streams, or DynamoDB Streams.

+```
**Key Features**
-* Prevent successfully processed messages from being returned to SQS
-* A simple interface for individually processing messages from a batch
+* Reports batch item failures to reduce number of retries for a record upon errors
+* Simple interface to process each batch record
+* Parallel processing of batches
+* Integrates with Java Events library and the deserialization module
+* Build your own batch processor by extending primitives
**Background**
-When using SQS as a Lambda event source mapping, Lambda functions can be triggered with a batch of messages from SQS.
-If your function fails to process any message from the batch, the entire batch returns to your SQS queue, and your
-Lambda function will be triggered with the same batch again. With this utility, messages within a batch will be handled individually - only messages that were not successfully processed
-are returned to the queue.
+When using SQS, Kinesis Data Streams, or DynamoDB Streams as a Lambda event source, your Lambda functions are
+triggered with a batch of messages.
+If your function fails to process any message from the batch, the entire batch returns to your queue or stream.
+This same batch is then retried until either condition happens first:
+**a)** your Lambda function returns a successful response,
+**b)** record reaches maximum retry attempts, or
+**c)** records expire.
+
+```mermaid
+journey
+ section Conditions
+ Successful response: 5: Success
+ Maximum retries: 3: Failure
+ Records expired: 1: Failure
+```
+
+This behavior changes when you enable Report Batch Item Failures feature in your Lambda function event source configuration:
+
+<!-- markdownlint-disable MD013 -->
+* [**SQS queues**](#sqs-standard). Only messages reported as failure will return to the queue for a retry, while successful ones will be deleted.
+* [**Kinesis data streams**](#kinesis-and-dynamodb-streams) and [**DynamoDB streams**](#kinesis-and-dynamodb-streams).
+Single reported failure will use its sequence number as the stream checkpoint.
+Multiple reported failures will use the lowest sequence number as checkpoint.
+
+With this utility, batch records are processed individually – only messages that failed to be processed
+return to the queue or stream for a further retry. You simply build a `BatchProcessor` in your handler,
+and return its response from the handler's `processMessage` implementation. Exceptions are handled
+internally and an appropriate partial response for the message source is returned to Lambda for you.
!!! warning
- While this utility lowers the chance of processing messages more than once, it is not guaranteed. We recommend implementing processing logic in an idempotent manner wherever possible.
+ While this utility lowers the chance of processing messages more than once, it is still not guaranteed.
+ We recommend implementing processing logic in an idempotent manner wherever possible, for instance,
+ by taking advantage of [the idempotency module](idempotency.md).
More details on how Lambda works with SQS can be found in the [AWS documentation](https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html)
## Install
-To install this utility, add the following dependency to your project.
+We simply add `powertools-batch` to our build dependencies. Note - if you are using other Powertools
+modules that require code-weaving, such as `powertools-core`, you will need to configure that also.

```
+## Getting Started
-## IAM Permissions
+For this feature to work, you need to **(1)** configure your Lambda function event source to use `ReportBatchItemFailures`,
+and **(2)** return a specific response to report which records failed to be processed.
-This utility requires additional permissions to work as expected. Lambda functions using this utility require the `sqs:DeleteMessageBatch` permission.
+You can use your preferred deployment framework to set the correct configuration while this utility,
+while the `powertools-batch` module handles generating the response, which simply needs to be returned as the result of
+your Lambda handler.
-If you are also using [nonRetryableExceptions](#move-non-retryable-messages-to-a-dead-letter-queue) attribute, utility will need additional permission of `sqs:GetQueueAttributes` on source SQS.
-It also needs `sqs:SendMessage` and `sqs:SendMessageBatch` on configured dead letter queue.
+A complete [Serverless Application Model](https://aws.amazon.com/serverless/sam/) example can be found [here](https://github.com/aws-powertools/powertools-lambda-java/tree/main/examples/powertools-examples-batch) covering all the batch sources.
-Refer [example project](https://github.com/aws-samples/aws-lambda-powertools-examples/blob/main/java/SqsBatchProcessing/template.yaml#L67) for policy details example.
+For more information on configuring `ReportBatchItemFailures`, see the details for [SQS](https://docs.aws.amazon.com/lambda/latest/dg/with-sqs.html#services-sqs-batchfailurereporting), [Kinesis](https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html#services-kinesis-batchfailurereporting), and [DynamoDB Streams](https://docs.aws.amazon.com/lambda/latest/dg/with-ddb.html#services-ddb-batchfailurereporting).
-## Processing messages from SQS
-You can use either **[SqsBatch annotation](#sqsbatch-annotation)**, or **[SqsUtils Utility API](#sqsutils-utility-api)** as a fluent API.
+!!! note "You do not need any additional IAM permissions to use this utility, except for what each event source requires."
-Both have nearly the same behaviour when it comes to processing messages from the batch:
+### Processing messages from SQS
-* **Entire batch has been successfully processed**, where your Lambda handler returned successfully, we will let SQS delete the batch to optimize your cost
-* **Entire Batch has been partially processed successfully**, where exceptions were raised within your `SqsMessageHandler` interface implementation, we will:
- - **1)** Delete successfully processed messages from the queue by directly calling `sqs:DeleteMessageBatch`
- - **2)** if, non retryable exceptions occur, messages resulting in configured exceptions during processing will be immediately moved to the dead letter queue associated to the source SQS queue or deleted from the source SQS queue if `deleteNonRetryableMessageFromQueue` is set to `true`.
- - **3)** Raise `SQSBatchProcessingException` to ensure failed messages return to your SQS queue
-
-The only difference is that **SqsUtils Utility API** will give you access to return from the processed messages if you need. Exception `SQSBatchProcessingException` thrown from the
-utility will have access to both successful and failed messaged along with failure exceptions.
-
-## Functional Interface SqsMessageHandler
-
-Both [annotation](#sqsbatch-annotation) and [SqsUtils Utility API](#sqsutils-utility-api) requires an implementation of functional interface `SqsMessageHandler`.
-
-This implementation is responsible for processing each individual message from the batch, and to raise an exception if unable to process any of the messages sent.
-
-**Any non-exception/successful return from your record handler function** will instruct utility to queue up each individual message for deletion.
-
-### SqsBatch annotation
-
-When using this annotation, you need provide a class implementation of `SqsMessageHandler` that will process individual messages from the batch - It should raise an exception if it is unable to process the record.
-
-All records in the batch will be passed to this handler for processing, even if exceptions are thrown - Here's the behaviour after completing the batch:
-
-* **Any successfully processed messages**, we will delete them from the queue via `sqs:DeleteMessageBatch`.
-* **if, nonRetryableExceptions attribute is used**, messages resulting in configured exceptions during processing will be immediately moved to the dead letter queue associated to the source SQS queue or deleted from the source SQS queue if `deleteNonRetryableMessageFromQueue` is set to `true`.
-* **Any unprocessed messages detected**, we will raise `SQSBatchProcessingException` to ensure failed messages return to your SQS queue.

-### SqsUtils Utility API
+## Parallel processing
+You can choose to process batch items in parallel using the `BatchMessageHandler#processBatchInParallel()`
+instead of `BatchMessageHandler#processBatch()`. Partial batch failure works the same way but items are processed
+in parallel rather than sequentially.
-If you require access to the result of processed messages, you can use this utility. The result from calling **`#!java SqsUtils#batchProcessor()`** on the context manager will be a list of all the return values
-from your **`#!java SqsMessageHandler#process()`** function.
+This feature is available for SQS, Kinesis and DynamoDB Streams but cannot be
+used with SQS FIFO. In that case, an `UnsupportedOperationException` is thrown.
-You can also use the utility in functional way by providing inline implementation of functional interface **`#!java SqsMessageHandler#process()`**
+!!! warning
+ Note that parallel processing is not always better than sequential processing,
+ and you should benchmark your code to determine the best approach for your use case.
+!!! info
+ To get more threads available (more vCPUs), you need to increase the amount of memory allocated to your Lambda function.
+ While it is possible to increase the number of threads using Java options or custom thread pools,
+ in most cases the defaults work well, and changing them is more likely to decrease performance
+ (see [here](https://www.baeldung.com/java-when-to-use-parallel-stream#fork-join-framework)
+ and [here](https://dzone.com/articles/be-aware-of-forkjoinpoolcommonpool)).
+ In situations where this may be useful, such as performing IO-bound work in parallel, make sure to measure before and after!

- @Override
- public List<String> handleRequest(SQSEvent input, Context context) {
- List<String> returnValues = SqsUtils.batchProcessor(input, SampleMessageHandler.class);
+When using parallel processing with X-Ray tracing enabled, the Tracing utility automatically handles trace context propagation to worker threads. This ensures that subsegments created during parallel message processing appear under the correct parent segment in your X-Ray trace, maintaining proper trace hierarchy and visibility into your batch processing performance.

-## Suppressing exceptions
+### Choosing the right concurrency model
-If you want to disable the default behavior where `SQSBatchProcessingException` is raised if there are any exception, you can pass the `suppressException` boolean argument.
+The `processBatchInParallel` method has two overloads with different concurrency characteristics:
-=== "Within SqsBatch annotation"
+#### Without custom executor (parallelStream)
- ```java hl_lines="2"
- @Override
- @SqsBatch(value = SampleMessageHandler.class, suppressException = true)
- public String handleRequest(SQSEvent input, Context context) {
- return "{\"statusCode\": 200}";
- }
- ```
+When you call `processBatchInParallel(event, context)` without providing an executor, the implementation uses Java's `parallelStream()` which leverages the common `ForkJoinPool`.
-=== "Within SqsUtils Utility API"
+**Best for: CPU-bound workloads**
- ```java hl_lines="3"
- @Override
- public List<String> handleRequest(SQSEvent input, Context context) {
- List<String> returnValues = SqsUtils.batchProcessor(input, true, SampleMessageHandler.class);
-
- return returnValues;
- }
- ```
+- Thread pool size matches available CPU cores
+- Optimized for computational tasks (data transformation, calculations, parsing)
+- Main thread participates in work-stealing
+- Simple to use with no configuration needed
-## Move non retryable messages to a dead letter queue
+```java
+// Good for CPU-intensive processing
+return handler.processBatchInParallel(sqsEvent, context);
+```
-If you want certain exceptions to be treated as permanent failures during batch processing, i.e. exceptions where the result of retrying will
-always be a failure and want these can be immediately moved to the dead letter queue associated to the source SQS queue, you can use `SqsBatch#nonRetryableExceptions()`
-to configure such exceptions.
+#### With custom executor (CompletableFuture)
-If you want such messages to be deleted instead, set `SqsBatch#deleteNonRetryableMessageFromQueue()` to `true`. By default, its value is `false`.
+When you call `processBatchInParallel(event, context, executor)` with a custom executor, the implementation uses `CompletableFuture` which gives you full control over the thread pool.
-Same capability is also provided by [SqsUtils Utility API](#sqsutils-utility-api).
+**Best for: I/O-bound workloads**
-!!! info
- Make sure the lambda function has required permissions needed by utility. Refer [this section](#iam-permissions).
+- You control thread pool size and characteristics
+- Ideal for I/O operations (HTTP calls, database queries, S3 operations)
+- Can use larger thread pools since threads spend time waiting, not computing
+- Main thread only waits; worker threads do all processing
-=== "SqsBatch annotation"
+```java
+// Good for I/O-intensive processing (API calls, DB queries, etc.)
+ExecutorService executor = Executors.newFixedThreadPool(50);
+return handler.processBatchInParallel(sqsEvent, context, executor);
+```
- ```java hl_lines="7 21"
- import software.amazon.lambda.powertools.sqs.SqsBatch;
- import software.amazon.lambda.powertools.sqs.SqsMessageHandler;
- import software.amazon.lambda.powertools.sqs.SqsUtils;
-
- public class AppSqsEvent implements RequestHandler<SQSEvent, String> {
- @Override
- @SqsBatch(value = SampleMessageHandler.class, nonRetryableExceptions = {IllegalArgumentException.class})
- public String handleRequest(SQSEvent input, Context context) {
- return "{\"statusCode\": 200}";
- }
-
- public class SampleMessageHandler implements SqsMessageHandler<Object> {
-
- @Override
- public String process(SQSMessage message) {
- // This will be called for each individual message from a batch
- // It should raise an exception if the message was not processed successfully
- String returnVal = doSomething(message.getBody());
+**For Java 21+: Virtual Threads**
- if(/**Business validation failure**/) {
- throw new IllegalArgumentException("Failed business validation. No point of retrying. Move me to DLQ." + message.getMessageId());
- }
+If you're using Java 21 or later, virtual threads are ideal for I/O-bound workloads:
- return returnVal;
- }
- }
+```java
+ExecutorService executor = Executors.newVirtualThreadPerTaskExecutor();
+return handler.processBatchInParallel(sqsEvent, context, executor);
+```
+
+Virtual threads are lightweight and can handle thousands of concurrent I/O operations efficiently without the overhead of platform threads.
+
+**Recommendation for typical Lambda SQS processing:**
+
+Most Lambda functions processing SQS messages perform I/O operations (calling APIs, querying databases, writing to S3). For these workloads, use the custom executor approach with a thread pool sized appropriately for your I/O operations or virtual threads for Java 21+.
+
+
+## Handling Messages
+
+### Raw message and deserialized message handlers
+You must provide either a raw message handler, or a deserialized message handler. The raw message handler receives
+the envelope record type relevant for the particular event source - for instance, the SQS event source provides
+[SQSMessage](https://javadoc.io/doc/com.amazonaws/aws-lambda-java-events/2.2.2/com/amazonaws/services/lambda/runtime/events/SQSEvent.html)
+instances. The deserialized message handler extracts the body from this envelope, and deserializes it to a user-defined
+type. Note that deserialized message handlers are not relevant for the DynamoDB provider, as the format of the inner
+message is fixed by DynamoDB.
+
+In general, the deserialized message handler should be used unless you need access to information on the envelope.
+
+=== "Raw Message Handler"
+
+ ```java hl_lines="4 7"
+ public void setup() {
+ BatchMessageHandler<SQSEvent, SQSBatchResponse> handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWithRawMessageHandler(this::processRawMessage);
+ }
+
+ private void processRawMessage(SQSEvent.SQSMessage sqsMessage) {
+ // Do something with the raw message
}
+
```

- import software.amazon.lambda.powertools.sqs.SqsBatch;
- import software.amazon.lambda.powertools.sqs.SqsMessageHandler;
- import software.amazon.lambda.powertools.sqs.SqsUtils;
-
- public class AppSqsEvent implements RequestHandler<SQSEvent, String> {
- @Override
- public String handleRequest(SQSEvent input, Context context) {
-
- SqsUtils.batchProcessor(input, BatchProcessor.class, IllegalArgumentException.class);
-
- return "{\"statusCode\": 200}";
- }
-
- public class SampleMessageHandler implements SqsMessageHandler<Object> {
+ ```java hl_lines="4 7"
+ public void setup() {
+ BatchMessageHandler<SQSEvent, SQSBatchResponse> handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWitMessageHandler(this::processRawMessage, Product.class);
+ }
+
+ private void processMessage(Product product) {
+ // Do something with the deserialized message
+ }
- @Override
- public String process(SQSMessage message) {
- // This will be called for each individual message from a batch
- // It should raise an exception if the message was not processed successfully
- String returnVal = doSomething(message.getBody());
+ ```
- if(/**Business validation failure**/) {
- throw new IllegalArgumentException("Failed business validation. No point of retrying. Move me to DLQ." + message.getMessageId());
- }
+### Success and failure handlers
+
+You can register a success or failure handler which will be invoked as each message is processed by the batch
+module. This may be useful for reporting - for instance, writing metrics or logging failures.
+
+These handlers are optional. Batch failures are handled by the module regardless of whether or not you
+provide a custom failure handler.
+
+Handlers can be provided when building the batch processor and are available for all event sources.
+For instance for DynamoDB:
+
+```java hl_lines="3 8"
+BatchMessageHandler<DynamodbEvent, StreamsEventResponse> handler = new BatchMessageHandlerBuilder()
+ .withDynamoDbBatchHandler()
+ .withSuccessHandler((m) -> {
+ // Success handler receives the raw message
+ LOGGER.info("Message with sequenceNumber {} was successfully processed",
+ m.getDynamodb().getSequenceNumber());
+ })

+[CloudFormation Custom resources](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-custom-resources.html)
provide a way for [AWS Lambda functions](
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-custom-resources-lambda.html) to execute

+provisioning logic whenever CloudFormation stacks are created, updated, or deleted.
-The utility provides a base `AbstractCustomResourceHandler` class which handles [custom resource request events](
-https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/crpg-ref-requests.html), constructs
-[custom resource responses](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/crpg-ref-responses.html), and
-sends them to the custom resources. Subclasses implement the provisioning logic and configure certain properties of
-these response objects.
+Powertools-cloudformation makes it easy to write Lambda functions in Java that are used as CloudFormation custom resources.
+The utility reads incoming CloudFormation events, calls your custom code depending on the operation (CREATE, UPDATE or DELETE) and sends responses back to CloudFormation.
+By using this library you do not need to write code to integrate with CloudFormation, and you only focus on writing the custom provisioning logic inside the Lambda function.
## Install
@@ -39,57 +37,90 @@ To install this utility, add the following dependency to your project.
## Usage
-Create a new `AbstractCustomResourceHandler` subclass and implement the `create`, `update`, and `delete` methods with
-provisioning logic in the appropriate methods(s).
+To utilise the feature, extend the `AbstractCustomResourceHandler` class in your Lambda handler class.
+Next, implement and override the following 3 methods: `create`, `update` and `delete`. The `AbstractCustomResourceHandler` invokes the right method according to the CloudFormation [custom resource request event](
+https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/crpg-ref-requests.html) it receives.
+Inside the methods, implement your custom provisioning logic, and return a `Response`. The `AbstractCustomResourceHandler` takes your `Response`, builds a
+[custom resource responses](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/crpg-ref-responses.html) and sends it to CloudFormation automatically.
-As an example, if a Lambda function only needs to provision something when a stack is created, put the provisioning
-logic exclusively within the `create` method; the other methods can just return `null`.
+Custom resources notify cloudformation either of `SUCCESS` or `FAILED` status. You have 2 utility methods to represent these responses: `Response.success(physicalResourceId)` and `Response.failed(physicalResourceId)`.
+The `physicalResourceId` is an identifier that is used during the lifecycle operations of the Custom Resource.
+You should generate a `physicalResourceId` during the `CREATE` operation, CloudFormation stores the `physicalResourceId` and includes it in `UPDATE` and `DELETE` events.
-```java hl_lines="8 9 10 11"

+ }else{
+ return Response.failed(physicalResourceId);
+ }
}
}
```
-### Signaling Provisioning Failures
+### Missing `Response` and exception handling
+
+If a `Response` is not returned by your code, `AbstractCustomResourceHandler` defaults the response to `SUCCESS`.
+If your code raises an exception (which is not handled), the `AbstractCustomResourceHandler` defaults the response to `FAILED`.
-If provisioning fails, the stack creation/modification/deletion as a whole can be failed by either throwing a
-`RuntimeException` or by explicitly returning a `Response` with a failed status, e.g. `Response.failure()`.
+In both of the scenarios, powertools-java will return the `physicalResourceId` to CloudFormation based on the following logic:
+- For CREATE operations, the `LogStreamName` from the Lambda context is used.
+- For UPDATE and DELETE operations, the `physicalResourceId` provided in the `CloudFormationCustomResourceEvent` is used.
-### Configuring Response Objects
+#### Why do you need a physicalResourceId?
-When provisioning results in data to be shared with other parts of the stack, include this data within the returned
-`Response` instance.
+It is recommended that you always explicitly provide a `physicalResourceId` in your response rather than letting Powertools for AWS Lambda (Java) generate if for you because `physicalResourceId` has a crucial role in the lifecycle of a CloudFormation custom resource.
+If the `physicalResourceId` changes between calls from Cloudformation, for instance in response to an `Update` event, Cloudformation [treats the resource update as a replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-cfn-customresource.html).
-This Lambda function creates a [Chime AppInstance](https://docs.aws.amazon.com/chime/latest/dg/create-app-instance.html)
+### Customising a response
+
+As well as the `Response.success(physicalResourceId)` and `Response.failed(physicalResourceId)`, you can customise the `Response` by using the `Response.builder()`.
+You customise the responses when you need additional attributes to be shared with other parts of the CloudFormation stack.
+
+In the example below, the Lambda function creates a [Chime AppInstance](https://docs.aws.amazon.com/chime/latest/dg/create-app-instance.html)
and maps the returned ARN to a "ChimeAppInstanceArn" attribute.

+## Advanced
+
+### Understanding the CloudFormation custom resource lifecycle
+
+While the library provides an easy-to-use interface, we recommend that you understand the lifecycle of CloudFormation custom resources before using them in production.
+
+#### Creating a custom resource
+When CloudFormation issues a `CREATE` on a custom resource, there are 2 possible states: `CREATE_COMPLETE` and `CREATE_FAILED`
+```mermaid
+stateDiagram
+ direction LR
+ createState: Create custom resource
+ [*] --> createState
+ createState --> CREATE_COMPLETE
+ createState --> CREATE_FAILED
+```
+
+If the resource is created successfully, the `physicalResourceId` is stored by CloudFormation for future operations.
+If the resource failed to create, CloudFormation triggers a rollback operation by default (rollback can be disabled, see [stack failure options](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stack-failure-options.html))
+
+#### Updating a custom resource
+CloudFormation issues an `UPDATE` operation on a custom resource only when one or more custom resource properties change.
+During the update, the custom resource may update successfully, or may fail the update.
+```mermaid
+stateDiagram
+ direction LR
+ updateState: Update custom resource
+ [*] --> updateState
+ updateState --> UPDATE_COMPLETE
+ updateState --> UPDATE_FAILED
+```
+
+In both of these scenarios, the custom resource can return the same `physicalResourceId` it received in the CloudFormation event, or a different `physicalResourceId`.
+Semantically an `UPDATE_COMPLETE` that returns the same `physicalResourceId` it received indicates that the existing resource was updated successfully.
+Instead, an `UPDATE_COMPLETE` with a different `physicalResourceId` means that a new physical resource was created successfully.
+```mermaid
+flowchart BT
+ id1(Logical resource)
+ id2(Previous physical Resource)
+ id3(New physical Resource)
+ id2 --> id1
+ id3 --> id1
+```
+Therefore, after the custom resource update completed or failed, there may be other cleanup operations by Cloudformation during the rollback, as described in the diagram below:
+```mermaid
+stateDiagram
+ state if_state <<choice>>
+ updateState: Update custom resource
+ deletePrev: DELETE resource with previous physicalResourceId
+ updatePrev: Rollback - UPDATE resource with previous properties
+ noOp: No further operations
+ [*] --> updateState
+ updateState --> UPDATE_COMPLETE
+ UPDATE_COMPLETE --> if_state
+ if_state --> noOp : Same physicalResourceId
+ if_state --> deletePrev : Different physicalResourceId
+ updateState --> UPDATE_FAILED
+ UPDATE_FAILED --> updatePrev
+```
+
+#### Deleting a custom resource
+
+CloudFormation issues a `DELETE` on a custom resource when:
+
+- the CloudFormation stack is being deleted
+- a new `physicalResourceId` was received during an update, and CloudFormation proceeds to rollback(DELETE) the custom resource with the previous `physicalResourceId`.
+
+```mermaid
+stateDiagram
+ direction LR
+ deleteState: Delete custom resource
+ [*] --> deleteState
+ deleteState --> DELETE_COMPLETE
+ deleteState --> DELETE_FAILED
+```

+title: Idempotency
+description: Utility
+---
+
+The idempotency utility provides a simple solution to convert your Lambda functions into idempotent operations which
+are safe to retry.
+
+## Terminology
+
+The property of idempotency means that an operation does not cause additional side effects if it is called more than
+once with the same input parameters.
+
+**Idempotent operations will return the same result when they are called multiple
+times with the same parameters**. This makes idempotent operations safe to retry. [Read more](https://aws.amazon.com/builders-library/making-retries-safe-with-idempotent-APIs/) about idempotency.
+
+**Idempotency key** is a hash representation of either the entire event or a specific configured subset of the event, and invocation results are **JSON serialized** and stored in your persistence storage layer.
+
+## Key features
+
+* Prevent Lambda handler function from executing more than once on the same event payload during a time window
+* Ensure Lambda handler returns the same result when called with the same payload
+* Select a subset of the event as the idempotency key using JMESPath expressions
+* Set a time window in which records with the same payload should be considered duplicates
+

+
+### Required resources
+
+Before getting started, you need to create a persistent storage layer where the idempotency utility can store its state - your Lambda functions will need read and write access to it.
+
+As of now, Amazon DynamoDB is the only supported persistent storage layer, so you'll need to create a table first or [bring your own persistence store](#bring-your-own-persistent-store).
+
+**Default table configuration**
+
+If you're not [changing the default configuration for the DynamoDB persistence layer](#dynamodbpersistencestore), this is the expected default configuration:
+
+| Configuration | Value | Notes |
+|--------------------|--------------|-------------------------------------------------------------------------------------|
+| Partition key | `id` | |
+| TTL attribute name | `expiration` | This can only be configured after your table is created if you're using AWS Console |
+
+!!! Tip "Tip: You can share a single state table for all functions"
+ You can reuse the same DynamoDB table to store idempotency state. We add your function name in addition to the idempotency key as a hash key.
+
+```yaml hl_lines="5-13 21-23 26" title="AWS Serverless Application Model (SAM) example"
+Resources:
+ IdempotencyTable:
+ Type: AWS::DynamoDB::Table
+ Properties:
+ AttributeDefinitions:
+ - AttributeName: id
+ AttributeType: S
+ KeySchema:
+ - AttributeName: id
+ KeyType: HASH
+ TimeToLiveSpecification:
+ AttributeName: expiration
+ Enabled: true
+ BillingMode: PAY_PER_REQUEST
+
+ IdempotencyFunction:
+ Type: AWS::Serverless::Function
+ Properties:
+ CodeUri: Function
+ Handler: helloworld.App::handleRequest
+ Policies:
+ - DynamoDBCrudPolicy:
+ TableName: !Ref IdempotencyTable
+ Environment:
+ Variables:
+ TABLE_NAME: !Ref IdempotencyTable
+```
+
+!!! warning "Warning: Large responses with DynamoDB persistence layer"
+ When using this utility with DynamoDB, your function's responses must be [smaller than 400KB](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Constraints.html#limits-items).
+ Larger items cannot be written to DynamoDB and will cause exceptions.
+
+!!! info "Info: DynamoDB"
+ Each function invocation will generally make 1 request to DynamoDB. If the
+ result returned by your Lambda is less than 1kb, you can expect 1 WCUs per invocation. For retried invocations, you will
+ see 1 WCU. In some cases, the utility might make 2 requests to DynamoDB in which case you will see 1 RCU and 1 WCU. Review the [DynamoDB pricing documentation](https://aws.amazon.com/dynamodb/pricing/) to
+ estimate the cost.
+
+### Basic usage
+
+You can use Powertools for AWS Lambda Idempotency with either the `@Idempotent` annotation or the functional API.
+
+!!! warning "Important"
+ Initialization and configuration of the `DynamoDBPersistenceStore` must be performed outside the handler, preferably in the constructor.
+
+=== "@Idempotent annotation"
+
+ ```java hl_lines="5-9 12 19"
+ public class App implements RequestHandler<Subscription, SubscriptionResult> {
+
+ public App() {
+ // We need to initialize idempotency store before the handleRequest method is called
+ Idempotency.config().withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build()
+ ).configure();
+ }
+
+ @Idempotent
+ public SubscriptionResult handleRequest(final Subscription event, final Context context) {
+ SubscriptionPayment payment = createSubscriptionPayment(
+ event.getUsername(),
+ event.getProductId()
+ );
+
+ return new SubscriptionResult(payment.getId(), "success", 200);
+ }
+ }
+
+ ```
+
+=== "Functional API"
+
+ ```java hl_lines="5-9 13-14"
+ public class App implements RequestHandler<Subscription, SubscriptionResult> {
+
+ public App() {
+ // We need to initialize idempotency store before the handleRequest method is called
+ Idempotency.config().withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build()
+ ).configure();
+ }
+
+ public SubscriptionResult handleRequest(final Subscription event, final Context context) {
+ Idempotency.registerLambdaContext(context);
+ return Idempotency.makeIdempotent(this::processSubscription, event, SubscriptionResult.class);
+ }
+
+ private SubscriptionResult processSubscription(Subscription event) {
+ SubscriptionPayment payment = createSubscriptionPayment(event.getUsername(), event.getProductId());
+ return new SubscriptionResult(payment.getId(), "success", 200);
+ }
+ }
+
+ ```
+
+=== "Example event"
+
+ ```json
+ {
+ "username": "xyz",
+ "product_id": "123456789"
+ }
+ ```
+
+#### Making non-handler methods idempotent
+
+You can make any synchronous Java function idempotent, not only the `handleRequest` handler.
+
+**With the `@Idempotent` annotation**, you must specify which parameter contains the idempotency key:
+
+ - If the method only has one parameter, it will be used by default.
+ - If there are 2 or more parameters, you must set the `@IdempotencyKey` on the parameter to use.
+
+**With the functional API**, you explicitly pass the idempotency key:
+
+ - For single-parameter methods, use `Idempotency.makeIdempotent(this::method, param, ReturnType.class)`
+ - For multi-parameter methods, use `Idempotency.makeIdempotent(idempotencyKey, () -> method(param1, param2), ReturnType.class)`
+
+!!! info "The parameter must be serializable in JSON. We use Jackson internally to (de)serialize objects"
+
+=== "@Idempotent annotation"
+
+ This example also demonstrates how you can integrate with [Batch utility](batch.md), so you can process each record in an idempotent manner.
+
+ ```java hl_lines="6-15 17-19 27-28"
+ public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ private final BatchMessageHandler<SQSEvent, SQSBatchResponse> handler;
+
+ public SqsBatchHandler() {
+ Idempotency.config()
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build()
+ ).withConfig(
+ IdempotencyConfig.builder()
+ .withEventKeyJMESPath("messageId")
+ .build()
+ ).configure();
+
+ handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWithRawMessageHandler(this::processMessage);
+ }
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ return handler.processBatch(sqsEvent, context);
+ }
+
+ @Idempotent
+ private void processMessage(@IdempotencyKey SQSEvent.SQSMessage message) {
+ // Process message
+ }
+ }
+ ```
+
+=== "Functional API"
+
+ This example also demonstrates how you can integrate with the [Batch utility](batch.md), so you can process each record in an idempotent manner. **Note: The JMESPath function still applies even when passing the idempotency key manually.**
+
+ ```java hl_lines="6-15 17-19 24 29"

+
+### Choosing a payload subset for idempotency
+
+!!! tip "Tip: Dealing with always changing payloads"
+ When dealing with an elaborate payload (API Gateway request for example), where parts of the payload always change, you should configure the **`EventKeyJMESPath`**.
+
+Use [`IdempotencyConfig`](#customizing-the-default-behavior) to instruct the Idempotent annotation to only use a portion of your payload to verify whether a request is idempotent, and therefore it should not be retried.
+
+> **Payment scenario**
+
+In this example, we have a Lambda handler that creates a payment for a user subscribing to a product. We want to ensure that we don't accidentally charge our customer by subscribing them more than once.
+
+Imagine the function executes successfully, but the client never receives the response due to a connection issue. It is safe to retry in this instance, as the idempotent decorator will return a previously saved response.
+
+!!! warning "Warning: Idempotency for JSON payloads"
+ The payload extracted by the `EventKeyJMESPath` is treated as a string by default, so will be sensitive to differences in whitespace even when the JSON payload itself is identical.
+
+ To alter this behaviour, you can use the [JMESPath built-in function](serialization.md#jmespath-functions) `powertools_json()` to treat the payload as a JSON object rather than a string.

+### Idempotency request flow
+
+This sequence diagram shows an example flow of what happens in the payment scenario:
+
+<center>
+```mermaid
+sequenceDiagram
+ participant Client
+ participant Lambda
+ participant Persistence Layer
+ alt initial request
+ Client->>Lambda: Invoke (event)
+ Lambda->>Persistence Layer: Get or set (id=event.search(payload))

+ Lambda->>Persistence Layer: Get or set (id=event.search(payload))
+ Persistence Layer-->>Lambda: Already exists in persistence layer. Return result
+ Lambda-->>Client: Response sent to client
+ end
+```
+<i>Idempotent sequence</i>
+</center>
+
+The client was successful in receiving the result after the retry. Since the Lambda handler was only executed once, our customer hasn't been charged twice.
+
+!!! note
+ Bear in mind that the entire Lambda handler is treated as a single idempotent operation. If your Lambda handler can cause multiple side effects, consider splitting it into separate functions.
+
+#### Lambda timeouts
+
+To prevent against extended failed retries when a [Lambda function times out](https://aws.amazon.com/premiumsupport/knowledge-center/lambda-verify-invocation-timeouts/), Powertools for AWS Lambda (Java) calculates and includes the remaining invocation available time as part of the idempotency record.
+
+!!! example
+ If a second invocation happens **after** this timestamp, and the record is marked as `INPROGRESS`, we will execute the invocation again as if it was in the `EXPIRED` state.
+ This means that if an invocation expired during execution, it will be quickly executed again on the next retry.
+
+**With the `@Idempotent` annotation**, this is automatically done when you annotate your Lambda handler.
+
+**With the functional API** or when using the `@Idempotent` annotation on methods other than the handler, you must call `Idempotency.registerLambdaContext(context)` to benefit from this protection.
+
+!!! important
+ Here is an example on how you register the Lambda context in your handler:
+
+ === "@Idempotent annotation"
+
+ ```java hl_lines="14" title="Registering the Lambda context"
+ public class PaymentHandler implements RequestHandler<SQSEvent, List<String>> {
+
+ public PaymentHandler() {
+ Idempotency.config()
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build())
+ .configure();
+ }
+
+ @Override
+ public List<String> handleRequest(SQSEvent sqsEvent, Context context) {
+ Idempotency.registerLambdaContext(context);
+ return sqsEvent.getRecords().stream().map(record -> process(record.getMessageId(), record.getBody())).collect(Collectors.toList());
+ }
+
+ @Idempotent
+ private String process(String messageId, @IdempotencyKey String messageBody) {
+ logger.info("Processing messageId: {}", messageId);
+ PaymentRequest request = extractDataFrom(messageBody).as(PaymentRequest.class);
+ return paymentService.process(request);
+ }
+
+ }
+ ```
+
+ === "Functional API"
+
+ ```java hl_lines="14" title="Registering the Lambda context"
+ public class PaymentHandler implements RequestHandler<SQSEvent, List<String>> {
+
+ public PaymentHandler() {
+ Idempotency.config()
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build())
+ .configure();
+ }
+
+ @Override
+ public List<String> handleRequest(SQSEvent sqsEvent, Context context) {
+ Idempotency.registerLambdaContext(context);
+ return sqsEvent.getRecords().stream()
+ .map(record -> Idempotency.makeIdempotent(
+ record.getBody(),
+ () -> process(record.getMessageId(), record.getBody()),
+ String.class))
+ .collect(Collectors.toList());
+ }
+
+ private String process(String messageId, String messageBody) {
+ logger.info("Processing messageId: {}", messageId);
+ PaymentRequest request = extractDataFrom(messageBody).as(PaymentRequest.class);
+ return paymentService.process(request);
+ }
+
+ }
+ ```
+
+#### Lambda timeout sequence diagram
+
+This sequence diagram shows an example flow of what happens if a Lambda function times out:
+
+<center>
+```mermaid
+sequenceDiagram
+ participant Client
+ participant Lambda
+ participant Persistence Layer
+ alt initial request
+ Client->>Lambda: Invoke (event)
+ Lambda->>Persistence Layer: Get or set (id=event.search(payload))

+ Note right of Persistence Layer: Locked to prevent concurrent<br/>invocations with <br/> the same payload.

+ Lambda-->>Client: Response sent to client
+ end
+```
+<i>Idempotent sequence for Lambda timeouts</i>
+</center>
+
+### Handling exceptions
+
+**With the `@Idempotent` annotation**, any unhandled exceptions that are thrown during the code execution will cause **the record in the persistence layer to be deleted**.
+This means that new invocations will execute your code again despite having the same payload. If you don't want the record to be deleted, you need to catch exceptions within the idempotent function and return a successful response.
+
+**With the functional API**, exceptions are handled the same way - unhandled exceptions will cause the record to be deleted. You should catch and handle exceptions within your idempotent function if you want to preserve the record.
+
+<center>
+```mermaid
+sequenceDiagram
+ participant Client
+ participant Lambda
+ participant Persistence Layer
+ Client->>Lambda: Invoke (event)
+ Lambda->>Persistence Layer: Get or set (id=event.search(payload))
+ activate Persistence Layer
+ Note right of Persistence Layer: Locked during this time. Prevents multiple<br/>Lambda invocations with the same<br/>payload running concurrently.
+ Lambda--xLambda: Call handler (event).<br/>Raises exception
+ Lambda->>Persistence Layer: Delete record (id=event.search(payload))
+ deactivate Persistence Layer
+ Lambda-->>Client: Return error response
+```
+<i>Idempotent sequence exception</i>
+</center>
+
+If an Exception is raised _outside_ the scope of a decorated method and after your method has been called, the persistent record will not be affected. In this case, idempotency will be maintained for your decorated function. Example:
+
+```java hl_lines="2-4 8-10" title="Exception not affecting idempotency record sample"
+ public SubscriptionResult handleRequest(final Subscription event, final Context context) {
+ // If an exception is thrown here, no idempotent record will ever get created as the
+ // idempotent function does not get called
+ doSomeStuff();
+
+ result = idempotentMethod(event);
+
+ // This exception will not cause the idempotent record to be deleted, since it
+ // happens after the decorated function has been successfully called
+ throw new Exception();
+ }
+
+ @Idempotent
+ private String idempotentMethod(final Subscription subscription) {
+ // perform some operation with no exception thrown
+ }
+```
+
+!!! warning
+ **We will throw an `IdempotencyPersistenceLayerException`** if any of the calls to the persistence layer fail unexpectedly.
+
+ As this happens outside the scope of your decorated function, you are not able to catch it.
+
+### Persistence stores
+
+#### DynamoDBPersistenceStore
+
+This persistence store is built-in, and you can either use an existing DynamoDB table or create a new one dedicated for idempotency state (recommended).
+
+Use the builder to customize the table structure:
+```java hl_lines="2-7" title="Customizing DynamoDBPersistenceStore to suit your table structure"
+DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .withKeyAttr("idempotency_key")
+ .withExpiryAttr("expires_at")
+ .withStatusAttr("current_status")
+ .withDataAttr("result_data")
+ .withValidationAttr("validation_key")
+ .build()
+```
+
+When using DynamoDB as a persistence layer, you can alter the attribute names by passing these parameters when initializing the persistence layer:
+
+| Parameter | Required | Default | Description |
+|--------------------|----------|--------------------------------------|--------------------------------------------------------------------------------------------------------|
+| **TableName** | Y | | Table name to store state |
+| **KeyAttr** | | `id` | Partition key of the table. Hashed representation of the payload (unless **SortKeyAttr** is specified) |
+| **ExpiryAttr** | | `expiration` | Unix timestamp of when record expires |
+| **StatusAttr** | | `status` | Stores status of the Lambda execution during and after invocation |
+| **DataAttr** | | `data` | Stores results of successfully idempotent methods |
+| **ValidationAttr** | | `validation` | Hashed representation of the parts of the event used for validation |
+| **SortKeyAttr** | | | Sort key of the table (if table is configured with a sort key). |
+| **StaticPkValue** | | `idempotency#{LAMBDA_FUNCTION_NAME}` | Static value to use as the partition key. Only used when **SortKeyAttr** is set. |
+
+## Advanced
+
+### Using explicit function names
+
+When using the functional API, if you need to call different methods with the same payload as the idempotency key, you must provide explicit function names to differentiate between them. This ensures each function has its own idempotency scope.
+
+=== "Functional API with explicit names"
+
+ ```java hl_lines="5-9 11-15"
+ public Response handleRequest(Order order, Context context) {
+ Idempotency.registerLambdaContext(context);
+
+ // Same orderId, different operations - need explicit function names
+ Idempotency.makeIdempotent(
+ "processPayment",
+ order.getId(),
+ () -> processPayment(order),
+ PaymentResult.class);
+
+ Idempotency.makeIdempotent(
+ "sendConfirmation",
+ order.getId(),
+ () -> sendEmail(order),
+ EmailResult.class);
+
+ return new Response("success");
+ }
+ ```
+
+!!! note
+ When using the `@Idempotent` annotation, the function name is automatically inferred from the method name, so this is not needed.
+
+### Generic return types support
+
+The functional API supports making methods with generic return types idempotent using Jackson's `TypeReference`. This is not possible with the `@Idempotent` annotation due to type erasure.
+
+=== "Functional API with TypeReference"
+
+ ```java hl_lines="1 6-10"
+ import com.fasterxml.jackson.core.type.TypeReference;
+
+ public Map<String, Basket> handleRequest(Product input, Context context) {
+ Idempotency.registerLambdaContext(context);
+
+ return Idempotency.makeIdempotent(
+ this::processProduct,
+ input,
+ new TypeReference<Map<String, Basket>>() {}
+ );
+ }
+
+ private Map<String, Basket> processProduct(Product product) {
+ // business logic returning generic type
+ Map<String, Basket> result = new HashMap<>();
+ // ...
+ return result;
+ }
+ ```
+
+### Customizing the default behavior
+
+Idempotency behavior can be further configured with **`IdempotencyConfig`** using a builder:
+
+```java hl_lines="2-9" title="Customizing IdempotencyConfig"
+IdempotencyConfig.builder()
+ .withEventKeyJMESPath("id")
+ .withPayloadValidationJMESPath("paymentId")
+ .withThrowOnNoIdempotencyKey(true)
+ .withExpiration(Duration.of(5, ChronoUnit.MINUTES))
+ .withUseLocalCache(true)
+ .withLocalCacheMaxItems(432)
+ .withHashFunction("SHA-256")
+ .withResponseHook((responseData, dataRecord) -> responseData)
+ .build()
+```
+
+These are the available options for further configuration:
+
+| Parameter | Default | Description |
+|---------------------------------------------------|---------|----------------------------------------------------------------------------------------------------------------------------------|
+| **EventKeyJMESPath** | `""` | JMESPath expression to extract the idempotency key from the event record. See available [built-in functions](serialization) |
+| **PayloadValidationJMESPath** | `""` | JMESPath expression to validate whether certain parameters have changed in the event |
+| **ThrowOnNoIdempotencyKey** | `false` | Throw exception if no idempotency key was found in the request |
+| **ExpirationInSeconds** | 3600 | The number of seconds to wait before a record is expired |
+| **UseLocalCache** | `false` | Whether to locally cache idempotency results (LRU cache) |
+| **LocalCacheMaxItems** | 256 | Max number of items to store in local cache |
+| **HashFunction** | `MD5` | Algorithm to use for calculating hashes, as supported by `java.security.MessageDigest` (eg. SHA-1, SHA-256, ...) |
+| **ResponseHook** | `null` | Response hook to apply modifications to idempotent responses |
+
+These features are detailed below.
+
+### Handling concurrent executions with the same payload
+
+This utility will throw an **`IdempotencyAlreadyInProgressException`** if we receive **multiple invocations with the same payload while the first invocation hasn't completed yet**.
+
+!!! info
+ If you receive `IdempotencyAlreadyInProgressException`, you can safely retry the operation.
+
+This is a locking mechanism for correctness. Since we don't know the result from the first invocation yet, we can't safely allow another concurrent execution.
+
+### Using in-memory cache
+
+**By default, in-memory local caching is disabled**, to avoid using memory in an unpredictable way.
+
+!!! warning Memory configuration of your function
+ Be sure to configure the Lambda memory according to the number of records and the potential size of each record.
+
+You can enable it as seen before with:
+```java title="Enable local cache"
+ IdempotencyConfig.builder()
+ .withUseLocalCache(true)
+ .build()
+```
+When enabled, we cache a maximum of 256 records in each Lambda execution environment - You can change it with the **`LocalCacheMaxItems`** parameter.
+
+!!! note "Note: This in-memory cache is local to each Lambda execution environment"
+ This means it will be effective in cases where your function's concurrency is low in comparison to the number of "retry" invocations with the same payload, because cache might be empty.
+
+
+### Expiring idempotency records
+
+!!! note
+ By default, we expire idempotency records after **an hour** (3600 seconds).
+
+In most cases, it is not desirable to store the idempotency records forever. Rather, you want to guarantee that the same payload won't be executed within a period of time.
+
+You can change this window with the **`ExpirationInSeconds`** parameter:
+```java title="Customizing expiration time"
+IdempotencyConfig.builder()
+ .withExpiration(Duration.of(5, ChronoUnit.MINUTES))
+ .build()
+```
+
+Records older than 5 minutes will be marked as expired, and the Lambda handler will be executed normally even if it is invoked with a matching payload.
+
+!!! note "Note: DynamoDB time-to-live field"
+ This utility uses **`expiration`** as the TTL field in DynamoDB, as [demonstrated in the SAM example earlier](#required-resources).
+
+### Payload validation
+
+!!! question "Question: What if your function is invoked with the same payload except some outer parameters have changed?"
+ Example: A payment transaction for a given productID was requested twice for the same customer, **however the amount to be paid has changed in the second transaction**.
+
+By default, we will return the same result as it returned before, however in this instance it may be misleading; we provide a fail fast payload validation to address this edge case.
+
+With **`PayloadValidationJMESPath`**, you can provide an additional JMESPath expression to specify which part of the event body should be validated against previous idempotent invocations

+ "productId": 1500,
+ "charge_type": "subscription",
+ "amount": 1
+ }
+ ```
+
+In this example, the **`userDetail`** and **`productId`** keys are used as the payload to generate the idempotency key, as per **`EventKeyJMESPath`** parameter.
+
+!!! note
+ If we try to send the same request but with a different amount, we will raise **`IdempotencyValidationException`**.
+
+Without payload validation, we would have returned the same result as we did for the initial request. Since we're also returning an amount in the response, this could be quite confusing for the client.
+
+By using **`withPayloadValidationJMESPath("amount")`**, we prevent this potentially confusing behavior and instead throw an Exception.
+
+### Making idempotency key required
+
+If you want to enforce that an idempotency key is required, you can set **`ThrowOnNoIdempotencyKey`** to `true`.
+
+This means that we will throw **`IdempotencyKeyException`** if the evaluation of **`EventKeyJMESPath`** is `null`.
+
+When set to `false` (the default), if the idempotency key is null, then the data is not persisted in the store.

+When creating the `DynamoDBPersistenceStore`, you can set a custom [`DynamoDbClient`](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/dynamodb/DynamoDbClient.html) if you need to customize the configuration:
+
+=== "Custom DynamoDbClient with X-Ray interceptor"
+
+ ```java hl_lines="2-8 13"
+ public App() {
+ DynamoDbClient customClient = DynamoDbClient.builder()
+ .region(Region.US_WEST_2)
+ .overrideConfiguration(ClientOverrideConfiguration.builder()
+ .addExecutionInterceptor(new TracingInterceptor())
+ .build()
+ )
+ .build();
+
+ Idempotency.config().withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .withDynamoDbClient(customClient)
+ .build()
+ ).configure();
+ }
+ ```
+
+!!! info "Default configuration is the following:"
+
+ ```java
+ DynamoDbClient.builder()
+ .credentialsProvider(EnvironmentVariableCredentialsProvider.create())
+ .httpClient(UrlConnectionHttpClient.builder().build())
+ .region(Region.of(System.getenv(AWS_REGION_ENV)))
+ .build();
+ ```
+
+### Using a DynamoDB table with a composite primary key
+
+When using a composite primary key table (hash+range key), use `SortKeyAttr` parameter when initializing your persistence store.
+
+With this setting, we will save the idempotency key in the sort key instead of the primary key. By default, the primary key will now be set to `idempotency#{LAMBDA_FUNCTION_NAME}`.
+
+You can optionally set a static value for the partition key using the `StaticPkValue` parameter.
+
+```java hl_lines="5" title="Reusing a DynamoDB table that uses a composite primary key"
+Idempotency.config().withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .withSortKeyAttr("sort_key")
+ .build())
+ .configure();
+```
+
+Data would then be stored in DynamoDB like this:
+
+| id | sort_key | expiration | status | data |
+|------------------------------|----------------------------------|------------|-------------|--------------------------------------|
+| idempotency#MyLambdaFunction | 1e956ef7da78d0cb890be999aecc0c9e | 1636549553 | COMPLETED | {"id": 12391, "message": "success"} |
+| idempotency#MyLambdaFunction | 2b2cdb5f86361e97b4383087c1ffdf27 | 1636549571 | COMPLETED | {"id": 527212, "message": "success"} |
+| idempotency#MyLambdaFunction | f091d2527ad1c78f05d54cc3f363be80 | 1636549585 | IN_PROGRESS | |
+
+### Bring your own persistent store
+
+This utility provides an abstract base class, so that you can implement your choice of persistent storage layer.
+
+You can extend the `BasePersistenceStore` class and implement the abstract methods `getRecord`, `putRecord`,
+`updateRecord` and `deleteRecord`. You can have a look at [`DynamoDBPersistenceStore`](https://github.com/aws-powertools/powertools-lambda-java/blob/master/powertools-idempotency/src/main/java/software/amazon/lambda/powertools/idempotency/persistence/DynamoDBPersistenceStore.java) as an implementation reference.
+
+!!! danger
+ Pay attention to the documentation for each method - you may need to perform additional checks inside these methods to ensure the idempotency guarantees remain intact.
+
+ For example, the `putRecord` method needs to throw an exception if a non-expired record already exists in the data store with a matching key.
+
+### Manipulating the Idempotent Response
+
+You can set up a response hook in the Idempotency configuration to manipulate the returned data when an operation is idempotent. The hook function will be called with the current de-serialized response `Object` and the Idempotency `DataRecord`.
+
+The example below shows how to append an HTTP header to an `APIGatewayProxyResponseEvent`.
+
+=== "Using an Idempotent Response Hook"
+
+ ```java hl_lines="3-20"
+ Idempotency.config().withConfig(
+ IdempotencyConfig.builder()
+ .withResponseHook((responseData, dataRecord) -> {
+ if (responseData instanceof APIGatewayProxyResponseEvent) {
+ APIGatewayProxyResponseEvent proxyResponse =
+ (APIGatewayProxyResponseEvent) responseData;
+ final Map<String, String> headers = new HashMap<>();
+ headers.putAll(proxyResponse.getHeaders());
+ // Append idempotency headers
+ headers.put("x-idempotency-response", "true");
+ headers.put("x-idempotency-expiration",
+ String.valueOf(dataRecord.getExpiryTimestamp()));
+
+ proxyResponse.setHeaders(headers);
+
+ return proxyResponse;
+ }
+
+ return responseData;
+ })
+ .build())
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build())
+ .configure();
+ ```
+
+???+ info "Info: Using custom de-serialization?"
+
+ The response hook is called after de-serialization so the payload you process will be the de-serialized Java object.
+
+#### Being a good citizen
+
+When using response hooks to manipulate returned data from idempotent operations, it's important to follow best practices to avoid introducing complexity or issues. Keep these guidelines in mind:
+
+1. **Response hook works exclusively when operations are idempotent.** The hook will not be called when an operation is not idempotent, or when the idempotent logic fails.
+
+2. **Catch and Handle Exceptions.** Your response hook code should catch and handle any exceptions that may arise from your logic. Unhandled exceptions will cause the Lambda function to fail unexpectedly.
+
+3. **Keep Hook Logic Simple** Response hooks should consist of minimal and straightforward logic for manipulating response data. Avoid complex conditional branching and aim for hooks that are easy to reason about.
+
+
+## Compatibility with other utilities
+
+### Validation utility
+
+The idempotency utility can be used with the `@Validation` annotation from the [validation module](validation.md). Ensure that idempotency is the innermost annotation.
+
+```java hl_lines="1 2" title="Using Idempotency with JSONSchema Validation utility"
+@Validation(inboundSchema = "classpath:/schema_in.json")
+@Idempotent
+public APIGatewayProxyResponseEvent handleRequest(APIGatewayProxyRequestEvent input, Context context) {
+ // ...
+}
+```
+
+!!! tip "Tip: JMESPath Powertools for AWS Lambda (Java) functions are also available"
+ Built-in functions like `powertools_json`, `powertools_base64`, `powertools_base64_gzip` are also available to use in this utility. See [JMESPath Powertools for AWS Lambda (Java) functions](serialization.md)
+
+
+## Testing your code
+
+The idempotency utility provides several routes to test your code.
+
+### Disabling the idempotency utility
+When testing your code, you may wish to disable the idempotency logic altogether and focus on testing your business logic. To do this, you can set the environment variable `POWERTOOLS_IDEMPOTENCY_DISABLED` to true.
+If you prefer setting this for specific tests, and are using JUnit 5, you can use [junit-pioneer](https://junit-pioneer.org/docs/environment-variables/) library:
+
+=== "MyFunctionTest.java"
+
+ ```java hl_lines="2"
+ @Test
+ @SetEnvironmentVariable(key = Constants.IDEMPOTENCY_DISABLED_ENV, value = "true")
+ public void testIdempotencyDisabled_shouldJustRunTheFunction() {
+ MyFunction func = new MyFunction();
+ func.handleRequest(someInput, mockedContext);
+ }
+ ```
+
+You can also disable the idempotency for all tests using `maven-surefire-plugin` and adding the environment variable:
+
+=== "pom.xml"
+```xml hl_lines="5-7"
+<plugin>
+ <groupId>org.apache.maven.plugins</groupId>
+ <artifactId>maven-surefire-plugin</artifactId>
+ <configuration>
+ <environmentVariables>
+ <POWERTOOLS_IDEMPOTENCY_DISABLED>true</POWERTOOLS_IDEMPOTENCY_DISABLED>
+ </environmentVariables>
+ </configuration>
+</plugin>
+```
+
+### Testing with DynamoDB Local

+title: Kafka Consumer
+description: Utility
+status: new

+
+<!-- markdownlint-disable MD043 -->
+
+The Kafka utility transparently handles message deserialization, provides an intuitive developer experience, and integrates seamlessly with the rest of the Powertools for AWS Lambda ecosystem.

+## Key features
+
+- Automatic deserialization of Kafka messages (JSON, Avro, and Protocol Buffers)
+- Simplified event record handling with familiar Kafka `ConsumerRecords` interface
+- Support for key and value deserialization
+- Support for ESM with and without Schema Registry integration
+- Proper error handling for deserialization issues
+
+## Terminology
+
+**Event Source Mapping (ESM)** A Lambda feature that reads from streaming sources (like Kafka) and invokes your Lambda function. It manages polling, batching, and error handling automatically, eliminating the need for consumer management code.
+
+**Record Key and Value** A Kafka messages contain two important parts: an optional key that determines the partition and a value containing the actual message data. Both are base64-encoded in Lambda events and can be independently deserialized.
+
+**Deserialization** Is the process of converting binary data (base64-encoded in Lambda events) into usable Java objects according to a specific format like JSON, Avro, or Protocol Buffers. Powertools handles this conversion automatically.
+
+**DeserializationType enum** Contains parameters that tell Powertools how to interpret message data, including the format type (JSON, Avro, Protocol Buffers).
+
+**Schema Registry** Is a centralized service that stores and validates schemas, ensuring producers and consumers maintain compatibility when message formats evolve over time.
+
+## Moving from traditional Kafka consumers
+
+Lambda processes Kafka messages as discrete events rather than continuous streams, requiring a different approach to consumer development that Powertools for AWS helps standardize.
+
+| Aspect | Traditional Kafka Consumers | Lambda Kafka Consumer |
+| --------------------- | ----------------------------------- | -------------------------------------------------------------- |
+| **Model** | Pull-based (you poll for messages) | Push-based (Lambda invoked with messages) |
+| **Scaling** | Manual scaling configuration | Automatic scaling to partition count |
+| **State** | Long-running application with state | Stateless, ephemeral executions |
+| **Offsets** | Manual offset management | Automatic offset commitment |
+| **Schema Validation** | Client-side schema validation | Optional Schema Registry integration with Event Source Mapping |
+| **Error Handling** | Per-message retry control | Batch-level retry policies |
+
+## Getting started
+
+### Installation
+
+Add the Powertools for AWS Lambda Kafka dependency to your project. Make sure to also add the `kafka-clients` library as a dependency. The utility supports `kafka-clients >= 3.0.0`.
+
+=== "Maven"
+
+ ```xml
+ <dependency>
+ <groupId>software.amazon.lambda</groupId>
+ <artifactId>powertools-kafka</artifactId>
+ <version>{{ powertools.version }}</version>
+ </dependency>
+ <!-- Kafka clients dependency - compatibility works for >= 3.0.0 -->
+ <dependency>
+ <groupId>org.apache.kafka</groupId>
+ <artifactId>kafka-clients</artifactId>
+ <version>4.0.0</version>
+ </dependency>
+ ```
+
+=== "Gradle"
+
+ ```gradle
+ dependencies {
+ implementation 'software.amazon.lambda:powertools-kafka:{{ powertools.version }}'
+ // Kafka clients dependency - compatibility works for >= 3.0.0
+ implementation 'org.apache.kafka:kafka-clients:4.0.0'
+ }
+ ```
+
+### Required resources
+
+To use the Kafka utility, you need an AWS Lambda function configured with a Kafka event source. This can be Amazon MSK, MSK Serverless, or a self-hosted Kafka cluster.
+
+=== "getting_started_with_msk.yaml"
+
+ ```yaml
+ AWSTemplateFormatVersion: '2010-09-09'
+ Transform: AWS::Serverless-2016-10-31
+ Resources:
+ KafkaConsumerFunction:
+ Type: AWS::Serverless::Function
+ Properties:
+ Handler: org.example.KafkaHandler::handleRequest
+ Runtime: java21
+ Timeout: 30
+ Events:
+ MSKEvent:
+ Type: MSK
+ Properties:
+ StartingPosition: LATEST
+ Stream: !GetAtt MyMSKCluster.Arn
+ Topics:
+ - my-topic-1
+ - my-topic-2
+ Policies:
+ - AWSLambdaMSKExecutionRole
+ ```
+
+### Using ESM with Schema Registry
+
+The Event Source Mapping configuration determines which mode is used. With `JSON`, Lambda converts all messages to JSON before invoking your function. With `SOURCE` mode, Lambda preserves the original format, requiring you function to handle the appropriate deserialization.
+
+Powertools for AWS supports both Schema Registry integration modes in your Event Source Mapping configuration.
+
+### Processing Kafka events
+
+The Kafka utility transforms raw Lambda Kafka events into an intuitive format for processing. To handle messages effectively, you'll need to configure the `@Deserialization` annotation that matches your data format. Based on the deserializer you choose, incoming records are directly transformed into your business objects which can be auto-generated classes from Avro / Protobuf or simple POJOs.
+
+<!-- prettier-ignore -->
+???+ tip "Using Avro is recommended"
+ We recommend Avro for production Kafka implementations due to its schema evolution capabilities, compact binary format, and integration with Schema Registry. This offers better type safety and forward/backward compatibility compared to JSON.

+
+### Handling primitive types
+
+When working with primitive data types (strings, integers, etc.) rather than structured objects, you can use any deserialization type such as `KAFKA_JSON`. Simply place the primitive type like `Integer` or `String` in the `ConsumerRecords` generic type parameters, and the library will automatically handle primitive type deserialization.
+
+<!-- prettier-ignore -->
+???+ tip "Common pattern: Keys with primitive values"
+ Using primitive types (strings, integers) as Kafka message keys is a common pattern for partitioning and identifying messages. Powertools automatically handles these primitive keys without requiring special configuration, making it easy to implement this popular design pattern.
+
+=== "Primitive key"

+
+### Message format support and comparison
+
+The Kafka utility supports multiple serialization formats to match your existing Kafka implementation. Choose the format that best suits your needs based on performance, schema evolution requirements, and ecosystem compatibility.
+
+<!-- prettier-ignore -->
+???+ tip "Selecting the right format"
+ For new applications, consider Avro or Protocol Buffers over JSON. Both provide schema validation, evolution support, and significantly better performance with smaller message sizes. Avro is particularly well-suited for Kafka due to its built-in schema evolution capabilities.
+
+=== "Supported Formats"
+
+ | Format | DeserializationType | Description | Required Dependencies |
+ |--------|---------------------|-------------|----------------------|
+ | **JSON** | `KAFKA_JSON` | Human-readable text format | Jackson |
+ | **Avro** | `KAFKA_AVRO` | Compact binary format with schema | Apache Avro |
+ | **Protocol Buffers** | `KAFKA_PROTOBUF` | Efficient binary format | Protocol Buffers |
+ | **Lambda Default** | `LAMBDA_DEFAULT` | Uses Lambda's built-in deserialization (equivalent to removing the `@Deserialization` annotation) | None |
+
+=== "Format Comparison"
+
+ | Feature | JSON | Avro | Protocol Buffers |
+ |---------|------|------|-----------------|
+ | **Schema Definition** | Optional | Required schema file | Required .proto file |
+ | **Schema Evolution** | None | Strong support | Strong support |
+ | **Size Efficiency** | Low | High | Highest |
+ | **Processing Speed** | Slower | Fast | Fastest |
+ | **Human Readability** | High | Low | Low |
+ | **Implementation Complexity** | Low | Medium | Medium |
+ | **Additional Dependencies** | None | Apache Avro | Protocol Buffers |
+
+Choose the serialization format that best fits your needs:
+
+- **JSON**: Best for simplicity and when schema flexibility is important
+- **Avro**: Best for systems with evolving schemas and when compatibility is critical
+- **Protocol Buffers**: Best for performance-critical systems with structured data
+- **Lambda Default**: Best for simple string-based messages or when using Lambda's built-in deserialization

+### Accessing record metadata
+
+Each Kafka record contains important metadata that you can access alongside the deserialized message content. This metadata helps with message processing, troubleshooting, and implementing advanced patterns like exactly-once processing.

+ import software.amazon.lambda.powertools.kafka.DeserializationType;
+ import software.amazon.lambda.powertools.logging.Logging;
+
+ public class MetadataKafkaHandler implements RequestHandler<ConsumerRecords<String, Customer>, String> {
+ private static final Logger LOGGER = LoggerFactory.getLogger(MetadataKafkaHandler.class);
+
+ @Override
+ @Logging
+ @Deserialization(type = DeserializationType.KAFKA_AVRO)
+ public String handleRequest(ConsumerRecords<String, Customer> records, Context context) {
+ for (ConsumerRecord<String, Customer> record : records) {
+ // Log record coordinates for tracing
+ LOGGER.info("Processing message from topic '{}'", record.topic());
+ LOGGER.info(" Partition: {}, Offset: {}", record.partition(), record.offset());
+ LOGGER.info(" Produced at: {}", record.timestamp());
+
+ // Process message headers
+ if (record.headers() != null) {
+ for (Header header : record.headers()) {
+ LOGGER.info(" Header: {} = {}",
+ header.key(), new String(header.value()));
+ }
+ }
+
+ // Access the Avro deserialized message content
+ Customer customer = record.value(); // Customer class is auto-generated from Avro schema
+ LOGGER.info("Processing order for: {}", customer.getName());
+ LOGGER.info("Order total: ${}", customer.getOrderTotal());
+ }
+ return "OK";
+ }
+ }
+ ```
+
+#### Available metadata properties
+
+| Property | Description | Example Use Case |
+| ----------------- | ----------------------------------------------- | ------------------------------------------- |
+| `topic()` | Topic name the record was published to | Routing logic in multi-topic consumers |
+| `partition()` | Kafka partition number | Tracking message distribution |
+| `offset()` | Position in the partition | De-duplication, exactly-once processing |
+| `timestamp()` | Unix timestamp when record was created | Event timing analysis |
+| `timestampType()` | Timestamp type (CREATE_TIME or LOG_APPEND_TIME) | Data lineage verification |
+| `headers()` | Key-value pairs attached to the message | Cross-cutting concerns like correlation IDs |
+| `key()` | Deserialized message key | Customer ID or entity identifier |
+| `value()` | Deserialized message content | The actual business data |
+
+### Error handling
+
+Handle errors gracefully when processing Kafka messages to ensure your application maintains resilience and provides clear diagnostic information. The Kafka utility integrates with standard Java exception handling patterns.
+
+<!-- prettier-ignore -->

+ // Optionally send to DLQ or error topic
+ sendToDlq(record);
+ }
+ }
+
+ return String.format("Processed %d records successfully, %d failed",

+
+ private void processOrder(Order order) {

+ ```
+
+### Integrating with Idempotency
+
+When processing Kafka messages in Lambda, failed batches can result in message reprocessing. The idempotency utility prevents duplicate processing by tracking which messages have already been handled, ensuring each message is processed exactly once.
+
+The Idempotency utility automatically stores the result of each successful operation, returning the cached result if the same message is processed again, which prevents potentially harmful duplicate operations like double-charging customers or double-counting metrics.
+
+=== "Idempotent Kafka Processing"
+
+ ```java
+ package org.example;
+
+ import com.amazonaws.services.lambda.runtime.Context;
+ import com.amazonaws.services.lambda.runtime.RequestHandler;
+ import org.apache.kafka.clients.consumer.ConsumerRecord;
+ import org.apache.kafka.clients.consumer.ConsumerRecords;

+ import software.amazon.lambda.powertools.idempotency.persistence.dynamodb.DynamoDBPersistenceStore;
+ import software.amazon.lambda.powertools.logging.Logging;
+
+ public class IdempotentKafkaHandler implements RequestHandler<ConsumerRecords<String, Payment>, String> {
+ private static final Logger LOGGER = LoggerFactory.getLogger(IdempotentKafkaHandler.class);
+
+ public IdempotentKafkaHandler() {
+ // Configure idempotency with DynamoDB persistence store
+ Idempotency.config()
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName("IdempotencyTable")
+ .build())
+ .configure();
+ }
+
+ @Override
+ @Logging
+ @Deserialization(type = DeserializationType.KAFKA_JSON)
+ public String handleRequest(ConsumerRecords<String, Payment> records, Context context) {
+ for (ConsumerRecord<String, Payment> record : records) {
+ // Payment class deserialized from JSON
+ Payment payment = record.value();
+
+ // Process each message with idempotency protection
+ processPayment(payment);
+ }
+ return "OK";
+ }
+
+ @Idempotent
+ private void processPayment(Payment payment) {
+ LOGGER.info("Processing payment {}", payment.getPaymentId());
+
+ // Your business logic here
+ PaymentService.process(payment.getPaymentId(), payment.getCustomerId(), payment.getAmount());
+ }
+ }
+ ```
+
+<!-- prettier-ignore -->
+???+ tip "Ensuring exactly-once processing"
+ The `@Idempotent` annotation will use the JSON representation of the Payment object to make sure that the same object is only processed exactly once. Even if a batch fails and Lambda retries the messages, each unique payment will be processed exactly once.
+
+### Best practices
+
+#### Batch size configuration
+
+The number of Kafka records processed per Lambda invocation is controlled by your Event Source Mapping configuration. Properly sized batches optimize cost and performance.
+
+=== "Batch size configuration"
+
+ ```yaml
+ Resources:
+ OrderProcessingFunction:
+ Type: AWS::Serverless::Function
+ Properties:
+ Handler: org.example.OrderHandler::handleRequest
+ Runtime: java21
+ Events:
+ KafkaEvent:
+ Type: MSK
+ Properties:
+ Stream: !GetAtt OrdersMSKCluster.Arn
+ Topics:
+ - order-events
+ - payment-events
+ # Configuration for optimal throughput/latency balance
+ BatchSize: 100
+ MaximumBatchingWindowInSeconds: 5
+ StartingPosition: LATEST
+ # Enable partial batch success reporting
+ FunctionResponseTypes:
+ - ReportBatchItemFailures
+ ```
+
+Different workloads benefit from different batch configurations:
+
+- **High-volume, simple processing**: Use larger batches (100-500 records) with short timeout
+- **Complex processing with database operations**: Use smaller batches (10-50 records)
+- **Mixed message sizes**: Set appropriate batching window (1-5 seconds) to handle variability
+
+#### Cross-language compatibility
+
+When using binary serialization formats across multiple programming languages, ensure consistent schema handling to prevent deserialization failures.
+
+=== "Using Python naming convention"
+
+ ```java hl_lines="33 36 39 42 56"
+ package org.example;
+
+ import com.amazonaws.services.lambda.runtime.Context;
+ import com.amazonaws.services.lambda.runtime.RequestHandler;
+ import org.apache.kafka.clients.consumer.ConsumerRecord;
+ import org.apache.kafka.clients.consumer.ConsumerRecords;
+ import org.slf4j.Logger;
+ import org.slf4j.LoggerFactory;
+ import software.amazon.lambda.powertools.kafka.Deserialization;
+ import software.amazon.lambda.powertools.kafka.DeserializationType;
+ import software.amazon.lambda.powertools.logging.Logging;
+ import com.fasterxml.jackson.annotation.JsonProperty;
+ import java.time.Instant;
+
+ public class CrossLanguageKafkaHandler implements RequestHandler<ConsumerRecords<String, OrderEvent>, String> {
+ private static final Logger LOGGER = LoggerFactory.getLogger(CrossLanguageKafkaHandler.class);
+
+ @Override
+ @Logging
+ @Deserialization(type = DeserializationType.KAFKA_JSON)
+ public String handleRequest(ConsumerRecords<String, OrderEvent> records, Context context) {
+ for (ConsumerRecord<String, OrderEvent> record : records) {
+ OrderEvent order = record.value(); // OrderEvent class handles JSON with Python field names
+ LOGGER.info("Processing order {} from {}",
+ order.getOrderId(), order.getOrderDate());
+ }
+ return "OK";
+ }
+ }
+
+ // Example class that handles Python snake_case field names
+ public class OrderEvent {
+ @JsonProperty("order_id")
+ private String orderId;
+
+ @JsonProperty("customer_id")
+ private String customerId;
+
+ @JsonProperty("total_amount")
+ private double totalAmount;
+
+ @JsonProperty("order_date")
+ private long orderDateMillis;
+
+ // Getters and setters
+ public String getOrderId() { return orderId; }
+ public void setOrderId(String orderId) { this.orderId = orderId; }
+
+ public String getCustomerId() { return customerId; }
+ public void setCustomerId(String customerId) { this.customerId = customerId; }
+
+ public double getTotalAmount() { return totalAmount; }
+ public void setTotalAmount(double totalAmount) { this.totalAmount = totalAmount; }
+
+ public Instant getOrderDate() {
+ return Instant.ofEpochMilli(orderDateMillis);
+ }
+ public void setOrderDate(long orderDateMillis) {
+ this.orderDateMillis = orderDateMillis;
+ }
+ }
+ ```
+
+Common cross-language challenges to address:
+
+- **Field naming conventions**: camelCase in Java vs snake_case in Python
+- **Date/time**: representation differences
+- **Numeric precision handling**: especially decimals
+
+### Troubleshooting
+
+#### Deserialization failures
+
+The Java Kafka utility registers a [custom Lambda serializer](https://docs.aws.amazon.com/lambda/latest/dg/java-custom-serialization.html) that performs **eager deserialization** of all records in the batch before your handler method is invoked.
+
+This means that if any record in the batch fails deserialization, a `RuntimeException` will be thrown with a concrete error message explaining why deserialization failed, and your handler method will never be called.
+
+**Key implications:**
+
+- **Batch-level failure**: If one record fails deserialization, the entire batch fails
+- **Early failure detection**: Deserialization errors are caught before your business logic runs
+- **Clear error messages**: The `RuntimeException` provides specific details about what went wrong
+- **No partial processing**: You cannot process some records while skipping failed ones within the same batch
+
+**Example of deserialization failure:**
+
+```java
+// If any record in the batch has invalid Avro data, you'll see:
+// RuntimeException: Failed to deserialize Kafka record: Invalid Avro schema for record at offset 12345
+```
+
+<!-- prettier-ignore -->
+!!! warning "Handler method not invoked on deserialization failure"
+ When deserialization fails, your `handleRequest` method will not be invoked at all. The `RuntimeException` is thrown before your handler code runs, preventing any processing of the batch.
+
+**Handling deserialization failures:**
+
+Since deserialization happens before your handler is called, you cannot catch these exceptions within your handler method. Instead, configure your Event Source Mapping with appropriate error handling:
+
+- **Dead Letter Queue (DLQ)**: Configure a DLQ to capture failed batches for later analysis
+- **Maximum Retry Attempts**: Set appropriate retry limits to avoid infinite retries
+- **Batch Size**: Use smaller batch sizes to minimize the impact of individual record failures
+
+```yaml
+# Example SAM template configuration for error handling
+Events:
+ KafkaEvent:
+ Type: MSK
+ Properties:
+ # ... other properties
+ BatchSize: 10 # Smaller batches reduce failure impact
+ MaximumRetryAttempts: 3
+ DestinationConfig:
+ OnFailure:
+ Type: SQS
+ Destination: !GetAtt DeadLetterQueue.Arn
+```
+
+#### Schema compatibility issues
+
+Schema compatibility issues often manifest as successful connections but failed deserialization. Common causes include:
+
+- **Schema evolution without backward compatibility**: New producer schema is incompatible with consumer schema
+- **Field type mismatches**: For example, a field changed from String to Integer across systems
+- **Missing required fields**: Fields required by the consumer schema but absent in the message
+- **Default value discrepancies**: Different handling of default values between languages
+
+When using Schema Registry, verify schema compatibility rules are properly configured for your topics and that all applications use the same registry.
+
+#### Memory and timeout optimization
+
+Lambda functions processing Kafka messages may encounter resource constraints, particularly with large batches or complex processing logic.
+
+For memory errors:
+
+- Increase Lambda memory allocation, which also provides more CPU resources
+- Process fewer records per batch by adjusting the `BatchSize` parameter in your event source mapping
+- Consider optimizing your message format to reduce memory footprint
+
+For timeout issues:
+
+- Extend your Lambda function timeout setting to accommodate processing time
+- Implement chunked or asynchronous processing patterns for time-consuming operations
+- Monitor and optimize database operations, external API calls, or other I/O operations in your handler
+
+<!-- prettier-ignore -->
+???+ tip "Monitoring memory usage"
+ Use CloudWatch metrics to track your function's memory utilization. If it consistently exceeds 80% of allocated memory, consider increasing the memory allocation or optimizing your code.

+## Extra Resources
+
+### Lambda Custom Serializers Compatibility
+
+This Kafka utility uses [Lambda custom serializers](https://docs.aws.amazon.com/lambda/latest/dg/java-custom-serialization.html) to provide automatic deserialization of Kafka messages.
+
+**Important compatibility considerations:**
+
+- **Existing custom serializers**: This utility will not be compatible if you already use your own custom Lambda serializer in your project
+- **Non-Kafka handlers**: Installing this library will not affect default Lambda serialization behavior for non-Kafka related handlers
+- **Kafka-specific**: The custom serialization only applies to handlers annotated with `@Deserialization`
+- **Lambda default fallback**: Using `@Deserialization(type = DeserializationType.LAMBDA_DEFAULT)` will proxy to Lambda's default serialization behavior
+
+**Need help with compatibility?**
+
+If you are blocked from adopting this utility due to existing custom serializers or other compatibility concerns, please contact us with your specific use-cases. We'd like to understand your requirements and explore potential solutions.
+
+For more information about Lambda custom serialization, see the [official AWS documentation](https://docs.aws.amazon.com/lambda/latest/dg/java-custom-serialization.html).

+title: Large Messages
+description: Utility
+---
+
+The large message utility handles SQS and SNS messages which have had their payloads
+offloaded to S3 if they are larger than the maximum allowed size (1 MB).
+
+## Features
+
+- Automatically retrieve the content of S3 objects when SQS or SNS messages have been offloaded to S3.
+- Automatically delete the S3 Objects after processing succeeds.
+- Compatible with the batch module (with SQS).

+
+SQS and SNS message payload is limited to 1MB. If you wish to send messages with a larger payload, you can leverage the
+[amazon-sqs-java-extended-client-lib](https://github.com/awslabs/amazon-sqs-java-extended-client-lib)
+or [amazon-sns-java-extended-client-lib](https://github.com/awslabs/amazon-sns-java-extended-client-lib) which
+offload the message to Amazon S3. See documentation
+([SQS](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-s3-messages.html)
+/ [SNS](https://docs.aws.amazon.com/sns/latest/dg/large-message-payloads.html))
+
+When offloaded to S3, the message contains a specific message attribute and the payload only contains a pointer to the
+S3 object (bucket and object key).
+
+This utility automatically retrieves messages which have been offloaded to S3 using the
+extended client libraries. Once a message's payload has been processed successfully, the
+utility deletes the payload from S3.
+
+This utility is compatible with
+versions *[1.1.0+](https://github.com/awslabs/amazon-sqs-java-extended-client-lib/releases/tag/1.1.0)* and *[2.0.0+](https://github.com/awslabs/amazon-sqs-java-extended-client-lib/releases/tag/2.0.0)*
+of [amazon-sqs-java-extended-client-lib](https://github.com/awslabs/amazon-sqs-java-extended-client-lib) / [amazon-sns-java-extended-client-lib](https://github.com/awslabs/amazon-sns-java-extended-client-lib).

+
+## Permissions
+
+As the utility interacts with Amazon S3, the lambda function must have the following permissions
+on the S3 bucket used for the large messages offloading:
+
+- `s3:GetObject`
+- `s3:DeleteObject`
+
+## Usage
+
+You can use the Large Messages utility with either the `@LargeMessage` annotation or the functional API.
+
+The `@LargeMessage` annotation can be used on any method where the *first* parameter is one of:
+
+- `SQSEvent.SQSMessage`
+- `SNSEvent.SNSRecord`
+
+The functional API `LargeMessages.processLargeMessage()` accepts the same message types.
+
+### Basic usage
+
+=== "@LargeMessage annotation - SQS"
+
+ ```java hl_lines="8 13 15"
+ import software.amazon.lambda.powertools.largemessages.LargeMessage;
+
+ public class SqsMessageHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent event, Context context) {
+ for (SQSMessage message: event.getRecords()) {
+ processRawMessage(message, context);
+ }
+ return SQSBatchResponse.builder().build();
+ }
+
+ @LargeMessage
+ private void processRawMessage(SQSEvent.SQSMessage sqsMessage, Context context) {
+ // sqsMessage.getBody() will contain the content of the S3 object
+ }
+ }
+ ```
+
+=== "Functional API - SQS"
+
+ ```java hl_lines="1 8"
+ import software.amazon.lambda.powertools.largemessages.LargeMessages;
+
+ public class SqsMessageHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent event, Context context) {
+ for (SQSMessage message: event.getRecords()) {
+ LargeMessages.processLargeMessage(message, this::processRawMessage);
+ }
+ return SQSBatchResponse.builder().build();
+ }
+
+ private void processRawMessage(SQSEvent.SQSMessage sqsMessage) {
+ // sqsMessage.getBody() will contain the content of the S3 object
+ }
+ }
+ ```
+
+=== "@LargeMessage annotation - SNS"
+
+ ```java hl_lines="7 11 13"
+ import software.amazon.lambda.powertools.largemessages.LargeMessage;
+
+ public class SnsRecordHandler implements RequestHandler<SNSEvent, String> {
+
+ @Override
+ public String handleRequest(SNSEvent event, Context context) {
+ processSNSRecord(event.records.get(0)); // there are always only one message
+ return "Hello World";
+ }
+
+ @LargeMessage
+ private void processSNSRecord(SNSEvent.SNSRecord snsRecord) {
+ // snsRecord.getSNS().getMessage() will contain the content of the S3 object
+ }
+ }
+ ```
+
+=== "Functional API - SNS"
+
+ ```java hl_lines="1 7"
+ import software.amazon.lambda.powertools.largemessages.LargeMessages;
+
+ public class SnsRecordHandler implements RequestHandler<SNSEvent, String> {
+
+ @Override
+ public String handleRequest(SNSEvent event, Context context) {
+ return LargeMessages.processLargeMessage(event.records.get(0), this::processSNSRecord);
+ }
+
+ private String processSNSRecord(SNSEvent.SNSRecord snsRecord) {
+ // snsRecord.getSNS().getMessage() will contain the content of the S3 object
+ return "Hello World";
+ }
+ }
+ ```
+
+When the Lambda function is invoked with a SQS or SNS event, the utility first
+checks if the content was offloaded to S3. In the case of a large message, there is a message attribute
+specifying the size of the offloaded message and the message contains a pointer to the S3 object.
+
+If this is the case, the utility will retrieve the object from S3 using the `getObject(bucket, key)` API,
+and place the content of the object in the message payload. You can then directly use the content of the message.
+If there was an error during the S3 download, the function will fail with a `LargeMessageProcessingException`.
+
+After your code is invoked and returns without error, the object is deleted from S3
+using the `deleteObject(bucket, key)` API. You can disable the deletion of S3 objects:
+
+=== "@LargeMessage annotation"
+ ```java
+ @LargeMessage(deleteS3Object = false)
+ private void processRawMessage(SQSEvent.SQSMessage sqsMessage) {
+ // do something with the message
+ }
+ ```
+
+=== "Functional API"
+ ```java
+ LargeMessages.processLargeMessage(message, this::processRawMessage, false);
+ ```
+
+!!! tip "Use together with batch module"
+ This utility works perfectly together with the batch module (`powertools-batch`), especially for SQS:
+
+ === "@LargeMessage annotation"
+ ```java hl_lines="2 5-7 12 15 16" title="Combining batch and large message modules"
+ public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+ private final BatchMessageHandler<SQSEvent, SQSBatchResponse> handler;
+
+ public SqsBatchHandler() {
+ handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWithRawMessageHandler(this::processMessage);
+ }
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ return handler.processBatch(sqsEvent, context);
+ }
+
+ @LargeMessage
+ private void processMessage(SQSEvent.SQSMessage sqsMessage) {
+ // do something with the message
+ }
+ }
+ ```
+
+ === "Functional API"
+ ```java hl_lines="7-9 14 18" title="Combining batch and large message modules"
+ import software.amazon.lambda.powertools.largemessages.LargeMessages;
+
+ public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+ private final BatchMessageHandler<SQSEvent, SQSBatchResponse> handler;
+
+ public SqsBatchHandler() {
+ handler = new BatchMessageHandlerBuilder()
+ .withSqsBatchHandler()
+ .buildWithRawMessageHandler(this::processMessage);
+ }
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ return handler.processBatch(sqsEvent, context);
+ }
+
+ private void processMessage(SQSEvent.SQSMessage sqsMessage) {
+ LargeMessages.processLargeMessage(sqsMessage, this::handleProcessedMessage);
+ }
+
+ private void handleProcessedMessage(SQSEvent.SQSMessage processedMessage) {
+ // do something with the message
+ }
+ }
+ ```
+
+!!! tip "Use together with idempotency module"
+ When using the `@LargeMessage` annotation, you can combine it with the `@Idempotent` annotation on the same method.
+ The `@Idempotent` takes precedence over the `@LargeMessage` annotation, meaning the Idempotency module will use the initial raw message (containing the S3 pointer) and not the large message.
+
+ When using the functional API, call `LargeMessages.processLargeMessage()` from within the `@Idempotent` method to ensure idempotency is based on the S3 pointer, not the unwrapped large blob.
+
+ === "@LargeMessage annotation"
+ ```java hl_lines="6 23-25" title="Combining idempotency and large message modules"
+ public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ public SqsBatchHandler() {
+ Idempotency.config().withConfig(
+ IdempotencyConfig.builder()
+ .withEventKeyJMESPath("body") // get the body of the message for the idempotency key
+ .build())
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("IDEMPOTENCY_TABLE"))
+ .build()
+ ).configure();
+ }
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ for (SQSMessage message: event.getRecords()) {
+ processRawMessage(message, context);
+ }
+ return SQSBatchResponse.builder().build();
+ }
+
+ @Idempotent
+ @LargeMessage
+ private String processRawMessage(@IdempotencyKey SQSEvent.SQSMessage sqsMessage, Context context) {
+ // do something with the message
+ }
+ }
+ ```
+
+ === "Functional API"
+ ```java hl_lines="8 25 27" title="Combining idempotency and large message modules"
+ import software.amazon.lambda.powertools.largemessages.LargeMessages;
+
+ public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
+
+ public SqsBatchHandler() {
+ Idempotency.config().withConfig(
+ IdempotencyConfig.builder()
+ .withEventKeyJMESPath("body") // get the body of the message for the idempotency key
+ .build())
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("IDEMPOTENCY_TABLE"))
+ .build()
+ ).configure();
+ }
+
+ @Override
+ public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
+ for (SQSMessage message: event.getRecords()) {
+ processRawMessage(message, context);
+ }
+ return SQSBatchResponse.builder().build();
+ }
+
+ @Idempotent
+ private String processRawMessage(@IdempotencyKey SQSEvent.SQSMessage sqsMessage, Context context) {
+ return LargeMessages.processLargeMessage(sqsMessage, this::handleProcessedMessage);
+ }
+
+ private String handleProcessedMessage(SQSEvent.SQSMessage processedMessage) {
+ // do something with the message
+ }
+ }
+ ```
+
+## Customizing S3 client configuration
+
+To interact with S3, the utility creates a default S3 Client:
+
+=== "Default S3 Client"
+ ```java
+ S3Client client = S3Client.builder()
+ .httpClient(UrlConnectionHttpClient.builder().build())
+ .region(Region.of(System.getenv(AWS_REGION_ENV)))
+ .build();
+ ```
+
+If you need to customize this `S3Client`, you can leverage the `LargeMessageConfig` singleton. This works with both the annotation and functional API:
+
+=== "@LargeMessage annotation"
+ ```java hl_lines="6"
+ import software.amazon.lambda.powertools.largemessages.LargeMessage;
+
+ public class SnsRecordHandler implements RequestHandler<SNSEvent, String> {
+
+ public SnsRecordHandler() {
+ LargeMessageConfig.init().withS3Client(/* put your custom S3Client here */);
+ }
+
+ @Override
+ public String handleRequest(SNSEvent event, Context context) {
+ processSNSRecord(event.records.get(0));
+ return "Hello World";
+ }
+
+ @LargeMessage
+ private void processSNSRecord(SNSEvent.SNSRecord snsRecord) {
+ // snsRecord.getSNS().getMessage() will contain the content of the S3 object
+ }
+ }
+ ```
+
+=== "Functional API"
+ ```java hl_lines="1 6"
+ import software.amazon.lambda.powertools.largemessages.LargeMessages;
+
+ public class SnsRecordHandler implements RequestHandler<SNSEvent, String> {
+
+ public SnsRecordHandler() {
+ LargeMessageConfig.init().withS3Client(/* put your custom S3Client here */);
+ }
+
+ @Override
+ public String handleRequest(SNSEvent event, Context context) {
+ return LargeMessages.processLargeMessage(event.records.get(0), this::processSNSRecord);
+ }
+
+ private String processSNSRecord(SNSEvent.SNSRecord snsRecord) {
+ // snsRecord.getSNS().getMessage() will contain the content of the S3 object
+ return "Hello World";
+ }
+ }
+ ```
+
+## Migration from the SQS Large Message utility
+
+- Replace the dependency in maven / gradle: `powertools-sqs` ==> `powertools-large-messages`
+- Replace the annotation: `@SqsLargeMessage` ==> `@LargeMessage` (the new module handles both SQS and SNS)
+- Move the annotation away from the Lambda `handleRequest` method and put it on a method with `SQSEvent.SQSMessage`
+ or `SNSEvent.SNSRecord` as first parameter.
+- The annotation now handles a single message, contrary to the previous version that was handling the complete batch.
+ It gives more control, especially when dealing with partial failures with SQS (see the batch module).
+- The new module only provides an annotation, an equivalent to the `SqsUtils` class is not available anymore in this new version.
+
+Finally, if you are still using the `powertools-sqs` library for batch processing, consider moving to `powertools-batch` at the same time to remove the dependency on this library completely; it has been deprecated and will be removed in v2.

-The parameters utility provides a way to retrieve parameter values from
-[AWS Systems Manager Parameter Store](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-parameter-store.html) or
-[AWS Secrets Manager](https://aws.amazon.com/secrets-manager/). It also provides a base class to create your parameter provider implementation.
-
-**Key features**
-
-* Retrieve one or multiple parameters from the underlying provider
+The parameters utilities provide a way to retrieve parameter values from
+[AWS Systems Manager Parameter Store](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-parameter-store.html),
+[AWS Secrets Manager](https://aws.amazon.com/secrets-manager/), [Amazon DynamoDB](https://aws.amazon.com/dynamodb/),

+
+## Key features
+
+* Retrieve one or multiple parameters from an underlying provider in a standard way
* Cache parameter values for a given amount of time (defaults to 5 seconds)
* Transform parameter values from JSON or base 64 encoded strings
+* GraalVM support
## Install
+In order to provide lightweight dependencies, each parameters module is available as its own
+package:
+
+* **Secrets Manager** - `powertools-parameters-secrets`
+* **SSM Parameter Store** - `powertools-parameters-ssm`
+* **Amazon DynamoDB** -`powertools-parameters-dynamodb`
+* **AWS AppConfig** - `powertools-parameters-appconfig`
-To install this utility, add the following dependency to your project.
+You can easily mix and match parameter providers within the same project for different needs.

**IAM Permissions**
This utility requires additional permissions to work as expected. See the table below:
-Provider | Function/Method | IAM Permission
-------------------------------------------------- | ------------------------------------------------- | ---------------------------------------------------------------------------------
-SSM Parameter Store | `SSMProvider.get(String)` `SSMProvider.get(String, Class)` | `ssm:GetParameter`
-SSM Parameter Store | `SSMProvider.getMultiple(String)` | `ssm:GetParametersByPath`
-Secrets Manager | `SecretsProvider.get(String)` `SecretsProvider.get(String, Class)` | `secretsmanager:GetSecretValue`
+| Provider | Function/Method | IAM Permission |
+|-----------|-------------------------------------------------------------------------|---------------------------------------------------------------------------|
+| SSM | `SSMProvider.get(String)` `SSMProvider.get(String, Class)` | `ssm:GetParameter` |
+| SSM | `SSMProvider.getMultiple(String)` | `ssm:GetParametersByPath` |
+| SSM | If using `withDecryption(true)` | You must add an additional permission `kms:Decrypt` |
+| Secrets | `SecretsProvider.get(String)` `SecretsProvider.get(String, Class)` | `secretsmanager:GetSecretValue` |
+| DynamoDB | `DynamoDBProvider.get(String)` `DynamoDBProvider.getMultiple(string)` | `dynamodb:GetItem` `dynamoDB:Query` |
+| AppConfig | `AppConfigProvider.get(String)` `AppConfigProvider.getMultiple(string)` | `appconfig:StartConfigurationSession`, `appConfig:GetLatestConfiguration` |
-## SSM Parameter Store
+## Retrieving Parameters
+You can retrieve parameters using either annotations or provider classes directly:
-You can retrieve a single parameter using SSMProvider.get() and pass the key of the parameter.
-For multiple parameters, you can use SSMProvider.getMultiple() and pass the path to retrieve them all.
+- **Annotations** (e.g., `@SecretsParam`, `@SSMParam`) - Simpler syntax with field injection, but requires AspectJ configuration
+- **Provider classes** (e.g., `SecretsProvider`, `SSMProvider`) - No AspectJ required, useful when you need to configure the underlying SDK client (e.g., different region or credentials), or prefer avoiding AspectJ setup
-Alternatively, you can retrieve an instance of a provider and configure its underlying SDK client,
-in order to get data from other regions or use specific credentials.
+## Built-in provider classes
-=== "SSMProvider"
+This section describes the built-in provider classes for each parameter store. For each provider, examples are shown for both the annotation-based approach and the provider class approach. In cases where a provider supports extra features, these will also be described.
- ```java hl_lines="6"
- import software.amazon.lambda.powertools.parameters.SSMProvider;
- import software.amazon.lambda.powertools.parameters.ParamManager;
+### Secrets Manager
- public class AppWithSSM implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
- // Get an instance of the SSM Provider
- SSMProvider ssmProvider = ParamManager.getSsmProvider();
-
- // Retrieve a single parameter
- String value = ssmProvider.get("/my/parameter");
-
- // Retrieve multiple parameters from a path prefix
- // This returns a Map with the parameter name as key
- Map<String, String> values = ssmProvider.getMultiple("/my/path/prefix");
+=== "@SecretsParam annotation"
+
+ ```java hl_lines="8 9"

- @Param(key = "/my/parameter/json" provider = SecretsProvider.class, transformer = JsonTransformer.class)
- ObjectToDeserialize value;
-
+=== "CustomProviderParam.java"
+
+ ```java
+ import java.lang.annotation.ElementType;
+ import java.lang.annotation.Retention;
+ import java.lang.annotation.RetentionPolicy;
+ import java.lang.annotation.Target;
+ import software.amazon.lambda.powertools.parameters.transform.Transformer;
+
+ /**

+
+## Easy deserialization
+
+### Key features
+
+* Easily deserialize the main content of an event (for example, the body of an API Gateway event)
+* 15+ built-in events (see the [list below](#built-in-events))
+
+### Getting started

+=== "Gradle"
+
+ ```
+ implementation 'software.amazon.lambda:powertools-serialization:{{ powertools.version }}'
+ ```
+
+### EventDeserializer
+
+The `EventDeserializer` can be used to extract the main part of an event (body, message, records) and deserialize it from JSON to your desired type.
+
+It can handle single elements like the body of an API Gateway event:
+
+=== "APIGWHandler.java"
+
+ ```java hl_lines="1 6 9"

+
+ public APIGatewayProxyResponseEvent handleRequest(
+ final APIGatewayProxyRequestEvent event,
+ final Context context) {
+
+ Product product = extractDataFrom(event).as(Product.class);
+
+ }
+ ```
+
+=== "Product.java"
+
+ ```java
+ public class Product {
+ private long id;
+ private String name;
+ private double price;
+
+ public Product() {
+ }
+
+ public Product(long id, String name, double price) {
+ this.id = id;
+ this.name = name;
+ this.price = price;
+ }
+
+ public long getId() {
+ return id;
+ }
+
+ public void setId(long id) {
+ this.id = id;
+ }
+
+ public String getName() {
+ return name;
+ }
+
+ public void setName(String name) {
+ this.name = name;
+ }
+
+ public double getPrice() {
+ return price;
+ }

+
+!!! Tip
+ In the background, `EventDeserializer` is using Jackson. The `ObjectMapper` is configured in `JsonConfig`. You can customize the configuration of the mapper if needed:
+ `JsonConfig.get().getObjectMapper()`. Using this feature, you don't need to add Jackson to your project and create another instance of `ObjectMapper`.

+## JMESPath functions
+
+!!! Tip
+ [JMESPath](https://jmespath.org/){target="_blank"} is a query language for JSON used by AWS CLI and Powertools for AWS Lambda (Java) to get a specific part of a json.
+
+### Key features
+
+* Deserialize JSON from JSON strings, base64, and compressed data
+* Use JMESPath to extract and combine data recursively
+
+### Getting started
+
+You might have events that contain encoded JSON payloads as string, base64, or even in compressed format. It is a common use case to decode and extract them partially or fully as part of your Lambda function invocation.
+
+You will generally use this in combination with other Powertools for AWS Lambda (Java) modules ([validation](validation.md) and [idempotency](idempotency.md)) where you might need to extract a portion of your data before using them.
+
+### Built-in functions
+
+Powertools for AWS Lambda (Java) provides the following JMESPath Functions to easily deserialize common encoded JSON payloads in Lambda functions:
+
+#### powertools_json function
+
+Use `powertools_json` function to decode any JSON string anywhere a JMESPath expression is allowed.
+
+Below example use this function to load the content from the body of an API Gateway request event as a JSON object and retrieve the id field in it:
+
+=== "MyHandler.java"
+
+ ```java hl_lines="7"
+ public class MyHandler implements RequestHandler<APIGatewayProxyRequestEvent, APIGatewayProxyResponseEvent> {
+
+ public MyHandler() {
+ Idempotency.config()
+ .withConfig(
+ IdempotencyConfig.builder()
+ .withEventKeyJMESPath("powertools_json(body).id")
+ .build())
+ .withPersistenceStore(
+ DynamoDBPersistenceStore.builder()
+ .withTableName(System.getenv("TABLE_NAME"))
+ .build())
+ .configure();
+ }
+
+ @Idempotent
+ public APIGatewayProxyResponseEvent handleRequest(final APIGatewayProxyRequestEvent event, final Context context) {
+ }
+ ```
+
+=== "event"
+
+ ```json hl_lines="2"
+ {
+ "body": "{\"message\": \"Lambda rocks\", \"id\": 43876123454654}",
+ "resource": "/{proxy+}",
+ "path": "/path/to/resource",
+ "httpMethod": "POST",
+ "queryStringParameters": {
+ "foo": "bar"
+ },
+ "headers": {
+ "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
+ "Accept-Encoding": "gzip, deflate, sdch",
+ "Accept-Language": "en-US,en;q=0.8",
+ "Cache-Control": "max-age=0",
+ },
+ "requestContext": {
+ "accountId": "123456789012",
+ "resourceId": "123456",
+ "stage": "prod",
+ "requestId": "c6af9ac6-7b61-11e6-9a41-93e8deadbeef",
+ "requestTime": "09/Apr/2015:12:34:56 +0000",
+ "requestTimeEpoch": 1428582896000,
+ "identity": {
+ "cognitoIdentityPoolId": null,

+ "cognitoIdentityId": null,
+ "caller": null,
+ "accessKey": null,
+ "sourceIp": "127.0.0.1",
+ "cognitoAuthenticationType": null,

+ "resourcePath": "/{proxy+}",
+ "httpMethod": "POST",
+ "apiId": "1234567890",
+ "protocol": "HTTP/1.1"
+ }
+ }
+ ```
+
+#### powertools_base64 function
+
+Use `powertools_base64` function to decode any base64 data.
+
+Below sample will decode the base64 value within the `data` key, and decode the JSON string into a valid JSON before we can validate it.
+
+=== "MyEventHandler.java"
+
+ ```java hl_lines="7"
+ import software.amazon.lambda.powertools.validation.ValidationUtils;
+
+ public class MyEventHandler implements RequestHandler<MyEvent, String> {
+
+ @Override
+ public String handleRequest(MyEvent myEvent, Context context) {
+ validate(myEvent, "classpath:/schema.json", "powertools_base64(data)");
+ return "OK";
+ }
+ }
+ ```
+=== "schema.json"
+```json
+{
+"data" : "ewogICJpZCI6IDQzMjQyLAogICJuYW1lIjogIkZvb0JhciBYWSIsCiAgInByaWNlIjogMjU4Cn0="
+}
+```
+
+#### powertools_base64_gzip function
+
+Use `powertools_base64_gzip` function to decompress and decode base64 data.
+
+Below sample will decompress and decode base64 data.
+
+=== "MyEventHandler.java"
+
+ ```java hl_lines="7"
+ import software.amazon.lambda.powertools.validation.ValidationUtils;
+
+ public class MyEventHandler implements RequestHandler<MyEvent, String> {
+
+ @Override
+ public String handleRequest(MyEvent myEvent, Context context) {
+ validate(myEvent, "classpath:/schema.json", "powertools_base64_gzip(data)");
+ return "OK";
+ }
+ }
+ ```
+
+=== "schema.json"
+
+ ```json
+ {
+ "data" : "H4sIAAAAAAAA/6vmUlBQykxRslIwMTYyMdIBcfMSc1OBAkpu+flOiUUKEZFKYOGCosxkkLiRqQVXLQDnWo6bOAAAAA=="
+ }
+ ```
+
+
+### Bring your own JMESPath function
+
+!!! warning
+ This should only be used for advanced use cases where you have special formats not covered by the built-in functions.
+ Please open an issue in Github if you need us to add some common functions.
+
+Your function must extend `io.burt.jmespath.function.BaseFunction`, take a String as parameter and return a String.
+You can read the [doc](https://github.com/burtcorp/jmespath-java#adding-custom-functions) for more information.
+
+Below is an example that takes some xml and transform it into json. Once your function is created, you need to add it
+to powertools.You can then use it to do your validation or in idempotency module.
+
+=== "XMLFunction.java"
+
+ ```java
+ public class XMLFunction extends BaseFunction {
+ public Base64Function() {
+ super("powertools_xml", ArgumentConstraints.typeOf(JmesPathType.STRING));
+ }
+
+ @Override
+ protected <T> T callFunction(Adapter<T> runtime, List<FunctionArgument<T>> arguments) {
+ T value = arguments.get(0).value();
+ String xmlString = runtime.toString(value);
+
+ String jsonString = // ... transform xmlString to json
+
+ return runtime.createString(jsonString);
+ }
+ }
+ ```
+
+=== "Handler with validation API"
+
+ ```java hl_lines="6 13"
+ ...
+ import software.amazon.lambda.powertools.validation.ValidationConfig;
+ import software.amazon.lambda.powertools.validation.ValidationUtils.validate;
+
+ static {
+ JsonConfig.get().addFunction(new XMLFunction());

-title: SQS Large Message Handling
-description: Utility
----
-
-The large message handling utility handles SQS messages which have had their payloads
-offloaded to S3 due to them being larger than the SQS maximum.
-
-The utility automatically retrieves messages which have been offloaded to S3 using the
-[amazon-sqs-java-extended-client-lib](https://github.com/awslabs/amazon-sqs-java-extended-client-lib)
-client library. Once the message payloads have been processed successful the
-utility can delete the message payloads from S3.
-
-This utility is compatible with versions *[1.1.0+](https://github.com/awslabs/amazon-sqs-java-extended-client-lib)* of amazon-sqs-java-extended-client-lib.

-## Lambda handler
-
-The annotation `@SqsLargeMessage` should be used with the handleRequest method of a class
-which implements `com.amazonaws.services.lambda.runtime.RequestHandler` with
-`com.amazonaws.services.lambda.runtime.events.SQSEvent` as the first parameter.
-
-=== "SqsMessageHandler.java"
-
- ```java hl_lines="6"
- import software.amazon.lambda.powertools.sqs.SqsLargeMessage;
-
- public class SqsMessageHandler implements RequestHandler<SQSEvent, String> {
-
- @Override
- @SqsLargeMessage
- public String handleRequest(SQSEvent sqsEvent, Context context) {
- // process messages
-
- return "ok";
- }
- }
- ```
-
-`@SqsLargeMessage` creates a default S3 Client `AmazonS3 amazonS3 = AmazonS3ClientBuilder.defaultClient()`.
-
-!!! tip
- When the Lambda function is invoked with an event from SQS, each received record
- in the SQSEvent is checked to see to validate if it is offloaded to S3.
- If it does then `getObject(bucket, key)` will be called, and the payload retrieved.
- If there is an error during this process then the function will fail with a `FailedProcessingLargePayloadException` exception.
-
- If the request handler method returns without error then each payload will be
- deleted from S3 using `deleteObject(bucket, key)`
-
-To disable deletion of payloads setting the following annotation parameter:
-
-=== "Disable payload deletion"
-
- ```java hl_lines="3"
- import software.amazon.lambda.powertools.sqs.SqsLargeMessage;
-
- @SqsLargeMessage(deletePayloads=false)
- public class SqsMessageHandler implements RequestHandler<SQSEvent, String> {
-
- }
- ```
-
-## Utility
-
-If you want to avoid using annotation and have control over error that can happen during payload enrichment use `SqsUtils.enrichedMessageFromS3()`.
-It provides you access with list of `SQSMessage` object enriched from S3 payload.
-
-Original `SQSEvent` object is never mutated. You can also control if the S3 payload should be deleted after successful
-processing.
-
-=== "Functional API without annotation"
-
- ```java hl_lines="9 10 11 14 15 16 17 18 19 20 21 22 27 28 29"
- import software.amazon.lambda.powertools.sqs.SqsLargeMessage;
- import software.amazon.lambda.powertools.sqs.SqsUtils;
-
- public class SqsMessageHandler implements RequestHandler<SQSEvent, String> {
-
- @Override
- public String handleRequest(SQSEvent sqsEvent, Context context) {
-
- Map<String, String> sqsMessage = SqsUtils.enrichedMessageFromS3(sqsEvent, sqsMessages -> {
- // Some business logic
- Map<String, String> someBusinessLogic = new HashMap<>();
- someBusinessLogic.put("Message", sqsMessages.get(0).getBody());
- return someBusinessLogic;
- });
-
- // Do not delete payload after processing.
- Map<String, String> sqsMessage = SqsUtils.enrichedMessageFromS3(sqsEvent, false, sqsMessages -> {
- // Some business logic
- Map<String, String> someBusinessLogic = new HashMap<>();
- someBusinessLogic.put("Message", sqsMessages.get(0).getBody());
- return someBusinessLogic;
- });
-
- // Better control over exception during enrichment
- try {
- // Do not delete payload after processing.
- SqsUtils.enrichedMessageFromS3(sqsEvent, false, sqsMessages -> {
- // Some business logic
- });
- } catch (FailedProcessingLargePayloadException e) {
- // handle any exception.
- }
-
- return "ok";
- }
- }
- ```
-
-## Overriding the default S3Client
-
-If you require customisations to the default S3Client, you can create your own `S3Client` and pass it to be used by utility either for
-**[SqsLargeMessage annotation](#lambda-handler)**, or **[SqsUtils Utility API](#utility)**.
-
-=== "App.java"
-
- ```java hl_lines="4 5 11"
- import software.amazon.lambda.powertools.sqs.SqsLargeMessage;
-
- static {
- SqsUtils.overrideS3Client(S3Client.builder()
- .build());

## Validating events
-You can validate inbound and outbound events using `@Validation` annotation.
+You can validate inbound and outbound events using either the `@Validation` annotation or the functional approach with `ValidationUtils.validate()` methods:
+
+- **@Validation annotation** - Simpler syntax with automatic validation, but requires AspectJ configuration
+- **ValidationUtils.validate()** - No AspectJ required, provides more control over the validation process such as handling validation errors
-You can also use the `Validator#validate()` methods, if you want more control over the validation process such as handling a validation error.
+We support JSON schema version 4, 6, 7, 2019-09 and 2020-12 using the [NetworkNT JSON Schema Validator](https://github.com/networknt/json-schema-validator) ([Compatibility with JSON Schema versions](https://github.com/networknt/json-schema-validator/blob/master/doc/compatibility.md)).
-We support JSON schema version 4, 6, 7 and 201909 (from [jmespath-jackson library](https://github.com/burtcorp/jmespath-java)).
+The validator is configured to enable format assertions by default even for 2019-09 and 2020-12.
### Validation annotation

## Custom events and responses
@@ -221,134 +244,46 @@ This is quite powerful because you can use JMESPath Query language to extract re
to [pipe expressions](https://jmespath.org/tutorial.html#pipe-expressions)
and [function](https://jmespath.org/tutorial.html#functions) expressions, where you'd extract what you need before validating the actual payload.
-## JMESPath functions
-
-JMESPath functions ensure to make an operation on a specific part of the json.validate
-
-Powertools provides two built-in functions:
-
-### powertools_base64 function
-
-Use `powertools_base64` function to decode any base64 data.
-
-Below sample will decode the base64 value within the data key, and decode the JSON string into a valid JSON before we can validate it.
-
-=== "MyEventHandler.java"
-
- ```java hl_lines="7"
- import software.amazon.lambda.powertools.validation.ValidationUtils;
-
- public class MyEventHandler implements RequestHandler<MyEvent, String> {
-
- @Override
- public String handleRequest(MyEvent myEvent, Context context) {
- validate(myEvent, "classpath:/schema.json", "powertools_base64(data)");
- return "OK";
- }
- }
- ```
-=== "schema.json"
- ```json
- {
- "data" : "ewogICJpZCI6IDQzMjQyLAogICJuYW1lIjogIkZvb0JhciBYWSIsCiAgInByaWNlIjogMjU4Cn0="
- }
- ```
-
-### powertools_base64_gzip function
-
-Use `powertools_base64_gzip` function to decompress and decode base64 data.
-
-Below sample will decompress and decode base64 data.
-
-=== "MyEventHandler.java"
-
- ```java hl_lines="7"
- import software.amazon.lambda.powertools.validation.ValidationUtils;
-
- public class MyEventHandler implements RequestHandler<MyEvent, String> {
-
- @Override
- public String handleRequest(MyEvent myEvent, Context context) {
- validate(myEvent, "classpath:/schema.json", "powertools_base64_gzip(data)");
- return "OK";
- }
- }

- }
- ```
-
-!!! note
- You don't need any function to transform a JSON String into a JSON object, powertools-validation will do it for you.
- In the 2 previous example, data contains JSON. Just provide the function to transform the base64 / gzipped / ... string into a clear JSON string.
-
-### Bring your own JMESPath function
-
-!!! warning
- This should only be used for advanced use cases where you have special formats not covered by the built-in functions.
- New functions will be added to the 2 built-in ones.
-Your function must extend `io.burt.jmespath.function.BaseFunction`, take a String as parameter and return a String.
-You can read the [doc](https://github.com/burtcorp/jmespath-java#adding-custom-functions) for more information.
-
-Below is an example that takes some xml and transform it into json. Once your function is created, you need to add it
-to powertools.You can then use it to do your validation or using annotation.
+## Change the schema version
+By default, powertools-validation is configured to use [V7](https://json-schema.org/draft-07/json-schema-release-notes.html) as the default dialect if [`$schema`](https://json-schema.org/understanding-json-schema/reference/schema#schema) is not explicitly specified within the schema. If [`$schema`](https://json-schema.org/understanding-json-schema/reference/schema#schema) is explicitly specified within the schema, the validator will use the specified dialect.
-=== "XMLFunction.java"
-
- ```java
- public class XMLFunction extends BaseFunction {
- public Base64Function() {
- super("powertools_xml", ArgumentConstraints.typeOf(JmesPathType.STRING));
- }
-
- @Override
- protected <T> T callFunction(Adapter<T> runtime, List<FunctionArgument<T>> arguments) {
- T value = arguments.get(0).value();
- String xmlString = runtime.toString(value);
-
- String jsonString = // ... transform xmlString to json
-
- return runtime.createString(jsonString);
- }
- }
- ```
+You can use the `ValidationConfig` to change that behaviour.

- ```java hl_lines="6"

+The Validation utility integrates with AWS Lambda SnapStart to improve restore durations. To make sure the SnapStart priming logic of this utility runs correctly, you need an explicit reference to `ValidationConfig` in your code to allow the library to register before SnapStart takes a memory snapshot. Learn more about what priming is in this [blog post](https://aws.amazon.com/blogs/compute/optimizing-cold-start-performance-of-aws-lambda-using-advanced-priming-strategies-with-snapstart/){target="_blank"}.

-# example
-
-This project contains source code and supporting files for a serverless application that you can deploy with the SAM CLI. It includes the following files and folders.
-
-- HelloWorldFunction/src/main - Code for the application's Lambda function.
-- events - Invocation events that you can use to invoke the function.
-- HelloWorldFunction/src/test - Unit tests for the application code.
-- template.yaml - A template that defines the application's AWS resources.
-
-The application uses several AWS resources, including Lambda functions and an API Gateway API. These resources are defined in the `template.yaml` file in this project. You can update the template to add AWS resources through the same deployment process that updates your application code.
-
-If you prefer to use an integrated development environment (IDE) to build and test your application, you can use the AWS Toolkit.
-The AWS Toolkit is an open source plug-in for popular IDEs that uses the SAM CLI to build and deploy serverless applications on AWS. The AWS Toolkit also adds a simplified step-through debugging experience for Lambda function code. See the following links to get started.
-
-* [PyCharm](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html)
-* [IntelliJ](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html)
-* [VS Code](https://docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/welcome.html)
-* [Visual Studio](https://docs.aws.amazon.com/toolkit-for-visual-studio/latest/user-guide/welcome.html)
-
-## Deploy the sample application
-
-The Serverless Application Model Command Line Interface (SAM CLI) is an extension of the AWS CLI that adds functionality for building and testing Lambda applications. It uses Docker to run your functions in an Amazon Linux environment that matches Lambda. It can also emulate your application's build environment and API.
-
-To use the SAM CLI, you need the following tools.
-
-* SAM CLI - [Install the SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html)
-* Java8 - [Install the Java SE Development Kit 8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
-* Maven - [Install Maven](https://maven.apache.org/install.html) or
-* Gradle - [Install Gradle](https://gradle.org/install/)
-* Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community)
-
-To build and deploy your application for the first time, run the following in your shell:
-
-```bash
-sam build
-sam deploy --guided
-```
-
-The first command will build the source of your application. The second command will package and deploy your application to AWS, with a series of prompts:
-
-* **Stack Name**: The name of the stack to deploy to CloudFormation. This should be unique to your account and region, and a good starting point would be something matching your project name.
-* **AWS Region**: The AWS region you want to deploy your app to.
-* **Confirm changes before deploy**: If set to yes, any change sets will be shown to you before execution for manual review. If set to no, the AWS SAM CLI will automatically deploy application changes.
-* **Allow SAM CLI IAM role creation**: Many AWS SAM templates, including this example, create AWS IAM roles required for the AWS Lambda function(s) included to access AWS services. By default, these are scoped down to minimum required permissions. To deploy an AWS CloudFormation stack which creates or modified IAM roles, the `CAPABILITY_IAM` value for `capabilities` must be provided. If permission isn't provided through this prompt, to deploy this example you must explicitly pass `--capabilities CAPABILITY_IAM` to the `sam deploy` command.
-* **Save arguments to samconfig.toml**: If set to yes, your choices will be saved to a configuration file inside the project, so that in the future you can just re-run `sam deploy` without parameters to deploy changes to your application.
-
-You can find your API Gateway Endpoint URL in the output values displayed after deployment.
-
-## Use the SAM CLI to build and test locally
-
-Build your application with the `sam build` command.
-
-```bash
-example$ sam build
-```
-
-The SAM CLI installs dependencies defined in `HelloWorldFunction/build.gradle`, creates a deployment package, and saves it in the `.aws-sam/build` folder.
-
-Test a single function by invoking it directly with a test event. An event is a JSON document that represents the input that the function receives from the event source. Test events are included in the `events` folder in this project.
-
-Run functions locally and invoke them with the `sam local invoke` command.
-
-```bash
-example$ sam local invoke HelloWorldFunction --event events/event.json
-```
-
-The SAM CLI can also emulate your application's API. Use the `sam local start-api` to run the API locally on port 3000.
-
-```bash
-example$ sam local start-api
-example$ curl http://localhost:3000/
-```
-
-The SAM CLI reads the application template to determine the API's routes and the functions that they invoke. The `Events` property on each function's definition includes the route and method for each path.
-
-```yaml
- Events:
- HelloWorld:
- Type: Api
- Properties:
- Path: /hello
- Method: get
-```
-
-## Add a resource to your application
-The application template uses AWS Serverless Application Model (AWS SAM) to define application resources. AWS SAM is an extension of AWS CloudFormation with a simpler syntax for configuring common serverless application resources such as functions, triggers, and APIs. For resources not included in [the SAM specification](https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md), you can use standard [AWS CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-template-resource-type-ref.html) resource types.
-
-## Fetch, tail, and filter Lambda function logs
-
-To simplify troubleshooting, SAM CLI has a command called `sam logs`. `sam logs` lets you fetch logs generated by your deployed Lambda function from the command line. In addition to printing the logs on the terminal, this command has several nifty features to help you quickly find the bug.
-
-`NOTE`: This command works for all AWS Lambda functions; not just the ones you deploy using SAM.
-
-```bash
-example$ sam logs -n HelloWorldFunction --stack-name sam-app --tail
-```
-
-You can find more information and examples about filtering Lambda function logs in the [SAM CLI Documentation](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-logging.html).
-
-## Unit tests
-
-Tests are defined in the `HelloWorldFunction/src/test` folder in this project.
-
-```bash
-example$ cd HelloWorldFunction
-HelloWorldFunction$ gradle test
-```
-
-## Cleanup
-
-To delete the sample application that you created, use the AWS CLI. Assuming you used your project name for the stack name, you can run the following:
-
-```bash
-aws cloudformation delete-stack --stack-name example
-```
-
-## Resources
-
-See the [AWS SAM developer guide](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/what-is-sam.html) for an introduction to SAM specification, the SAM CLI, and serverless application concepts.
-
-Next, you can use AWS Serverless Application Repository to deploy ready to use Apps that go beyond hello world samples and learn how authors developed their applications: [AWS Serverless Application Repository main page](https://aws.amazon.com/serverless/serverlessrepo/)

+
+## Working with AWS Serverless Application Model (SAM) Examples
+Many of the examples use [AWS Serverless Application Model](https://aws.amazon.com/serverless/sam/) (SAM). To get started with them, you can use the SAM Command Line Interface (SAM CLI) to build it and deploy an example to AWS.
+
+To use the SAM CLI, you need the following tools.
+
+* SAM CLI - [Install the SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html)
+* Java11 - [Install the Java 11](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html)
+* Maven - [Install Maven](https://maven.apache.org/install.html)
+* Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community)
+
+To learn more about SAM, [check out the developer guide](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/using-sam-cli.html). You can use the CLI to [test events locally](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/using-sam-cli-local-invoke.html), and [run the application locally](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/using-sam-cli-local-start-api.html), amongst other things.

+To build and deploy an example application for the first time, run the following in your shell:
+
+```bash
+# Switch to the directory containing an example for the powertools-idempotency module
+$ cd powertools-examples-idempotency/sam
+
+# Build and deploy the example
+$ sam build
+$ sam deploy --guided
+```
+
+The first command will build the source of your application. The second command will package and deploy your application to AWS, with a series of prompts:
+
+* **Stack Name**: The name of the stack to deploy to CloudFormation. This should be unique to your account and region, and a good starting point would be something matching your project name.
+* **AWS Region**: The AWS region you want to deploy your app to.
+* **Confirm changes before deploy**: If set to yes, any change sets will be shown to you before execution for manual review. If set to no, the AWS SAM CLI will automatically deploy application changes.
+* **Allow SAM CLI IAM role creation**: Many AWS SAM templates, including this example, create AWS IAM roles required for the AWS Lambda function(s) included to access AWS services. By default, these are scoped down to minimum required permissions. To deploy an AWS CloudFormation stack which creates or modified IAM roles, the `CAPABILITY_IAM` value for `capabilities` must be provided. If permission isn't provided through this prompt, to deploy this example you must explicitly pass `--capabilities CAPABILITY_IAM` to the `sam deploy` command.
+* **Save arguments to samconfig.toml**: If set to yes, your choices will be saved to a configuration file inside the project, so that in the future you can just re-run `sam deploy` without parameters to deploy changes to your application.
+
+You can find your API Gateway Endpoint URL in the output values displayed after deployment.
+
+If you're not using SAM, you can look for examples for other tools under [powertools-examples-core-utilities](./powertools-examples-core-utilities)
+
+### External examples
+
+You can find more examples in the https://github.com/aws/aws-sam-cli-app-templates project:
+
+* [Java 11 + Maven](https://github.com/aws/aws-sam-cli-app-templates/tree/master/java11/hello-pt-maven)
+* [Java 17 + Maven](https://github.com/aws/aws-sam-cli-app-templates/tree/master/java17/hello-pt-maven)
+* [Java 17 + Gradle](https://github.com/aws/aws-sam-cli-app-templates/tree/master/java17/hello-pt-gradle)
+
+
+### SAM - Other Tools
+
+If you prefer to use an integrated development environment (IDE) to build and test your application, you can use the AWS Toolkit. The AWS Toolkit is an open source plug-in for popular IDEs that uses the SAM CLI to build and deploy serverless applications on AWS. The AWS Toolkit also adds a simplified step-through debugging experience for Lambda function code. See the following links to get started.

+ # Powertools for AWS Lambda (Java) - Batch Example
+
+This project contains examples of Lambda function using the batch processing module of Powertools for AWS Lambda (Java).
+For more information on this module, please refer to the
+[documentation](https://docs.powertools.aws.dev/lambda-java/utilities/batch/).
+
+Three different examples and SAM deployments are included, covering each of the batch sources:
+
+* [SQS](src/main/java/org/demo/batch/sqs) - SQS batch processing
+* [Kinesis Streams](src/main/java/org/demo/batch/kinesis) - Kinesis Streams batch processing
+* [DynamoDB Streams](src/main/java/org/demo/batch/dynamo) - DynamoDB Streams batch processing
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../README.md)
+
+This sample contains three different deployments, depending on which batch processor you'd like to use, you can
+change to the subdirectory containing the example SAM template, and deploy. For instance, for the SQS batch
+deployment:
+
+```bash
+cd deploy/sqs
+sam build
+sam deploy --guided
+```
+
+## Test the application
+
+Each of the examples uses a Lambda scheduled every 5 minutes to push a batch, and a separate lambda to read it. To
+see this in action, we can simply tail the logs of our stack:
+
+```bash
+sam logs --tail $STACK_NAME
+```

+# Powertools for AWS Lambda (Java) - Cloudformation Custom Resource Example
+
+This project contains an example of Lambda function using the CloudFormation module of Powertools for AWS Lambda in Java. For more information on this module, please refer to the [documentation](https://awslabs.github.io/aws-lambda-powertools-java/utilities/custom_resources/).
+
+In this example you pass in a bucket name as a parameter and upon CloudFormation events a call is made to a lambda. That lambda attempts to create the bucket on CREATE events, create a new bucket if the name changes with an UPDATE event and delete the bucket upon DELETE events.
+
+## Deploy the sample application
+
+This sample can be used either with the Serverless Application Model (SAM) or with CDK.
+
+### Deploy with SAM CLI
+To deploy it using the SAM CLI, check out the instructions for getting started in [the examples directory](../README.md)
+Run the following in your shell:
+
+```bash
+cd infra/sam
+sam build
+sam deploy --guided --parameter-overrides BucketNameParam=my-unique-bucket-2.9.0718
+```
+
+### Deploy with CDK
+To use CDK you need the following tools.
+
+* CDK - [Install CDK](https://docs.aws.amazon.com/cdk/v2/guide/getting_started.html)
+* Java 11 - [Install Java 11](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html)
+* Maven - [Install Maven](https://maven.apache.org/install.html)
+* Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community)
+
+To build and deploy this application for the first time, run the following in your shell:
+
+```bash
+cd infra/cdk
+mvn package
+cdk synth
+cdk deploy -c BucketNameParam=my-unique-bucket-2.9.0718

+# Powertools for AWS Lambda (Java) - CloudFormation Custom Resource Example with SAM on GraalVM
+
+This project contains an example of a Lambda function using the CloudFormation module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/custom_resources/).
+
+In this example you pass in a bucket name as a parameter and upon CloudFormation events a call is made to a lambda. That lambda attempts to create the bucket on CREATE events, create a new bucket if the name changes with an UPDATE event and delete the bucket upon DELETE events.
+
+Have a look at [App.java](../../src/main/java/helloworld/App.java) for the full details.
+
+## Build the sample application
+
+> [!NOTE]
+> Building AWS Lambda packages on macOS (ARM64/Intel) for deployment on AWS Lambda (Linux x86_64 or ARM64) will result in incompatible binary dependencies that cause import errors at runtime.
+
+Choose the appropriate build method based on your operating system:
+
+### Build locally using Docker
+
+Recommended for macOS and Windows users: Cross-compile using Docker to match target platform of Lambda:
+
+```shell
+docker build --platform linux/amd64 . -t powertools-examples-cloudformation-sam-graalvm
+docker run --platform linux/amd64 -it -v `pwd`/../..:`pwd`/../.. -w `pwd`/../.. -v ~/.m2:/root/.m2 powertools-examples-cloudformation-sam-graalvm mvn clean -Pnative-image package -DskipTests
+sam build --use-container --build-image powertools-examples-cloudformation-sam-graalvm
+```
+
+**Note**: The Docker run command mounts your local Maven cache (`~/.m2`) and builds the native binary with SNAPSHOT support, then SAM packages the pre-built binary.
+
+### Build on native OS
+
+For Linux users with GraalVM installed:
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+cd ../..
+mvn clean -Pnative-image package -DskipTests
+cd infra/sam-graalvm
+sam build
+```
+
+## Deploy the sample application
+
+```shell
+sam deploy --guided --parameter-overrides BucketNameParam=my-unique-bucket-2.9.0718
+```
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting started with SAM in [the examples directory](../../../README.md)
+
+## Test the application
+
+The CloudFormation custom resource will be triggered automatically during stack deployment. You can monitor the Lambda function execution in CloudWatch Logs to see the custom resource handling CREATE, UPDATE, and DELETE events for the S3 bucket.
+

+# Powertools for AWS Lambda (Java) - Core Utilities Example
+
+This project demonstrates the Lambda for Powertools Java module - including
+[logging](https://docs.powertools.aws.dev/lambda/java/core/logging/),
+[tracing](https://docs.powertools.aws.dev/lambda/java/core/tracing/), and
+[metrics](https://docs.powertools.aws.dev/lambda/java/core/metrics/).
+
+The example application is the same, and you can now also use Kotlin!
+
+## Java
+* [AWS SAM](sam/)
+* [AWS CDK](cdk/)
+* [Serverless framework](serverless/)
+* [Terraform](terraform/)
+
+We also provide an example showing the integration of SAM, Powertools, and Gradle:
+
+* [AWS SAM with a Gradle build](gradle/)
+
+- App.java - Code for the application's Lambda function.
+- AppTests.java - Unit tests for the application code.
+- events - Invocation events that you can use to invoke the function.
+
+Configuration files and deployment process for each tool are described in corresponding README files.
+
+## Kotlin
+
+- [Gradle](kotlin/)
+
+Example application consists of the following files:
+
+- App.kt - Code for the application's Lambda function.
+- AppTests.kt - Unit tests for the application code.
+- events - Invocation events that you can use to invoke the function.
+
+Configuration files and deployment process for each tool are described in corresponding README files.
+
+## Test the application
+
+Once the app is deployed, you can invoke the endpoint like this:
+
+```bash
+ curl https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/hello/
+```
+
+The response itself isn't particularly interesting - you will get back some information about your IP address. If
+you go to the Lambda Console and locate the lambda you have deployed, then click the "Monitoring" tab you will
+be able to find:
+
+- **View X-Ray traces** - Display the traces captured by the traces module. These include subsegments for the
+ different function calls within the example
+- **View Cloudwatch logs** - Display the structured logging output of the example
+
+Likewise, from the CloudWatch dashboard, under **Metrics**, **all metrics**, you will find the namespaces `Another`
+and `ServerlessAirline`. The values in each of these are published by the code in the respective application's Lambda function.

+# Powertools for AWS Lambda (Java) - Core Utilities Example with CDK
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Cloud Development Kit](https://aws.amazon.com/cdk/).
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+CDK uses the following project structure:
+- [app](app) - stores the source code of your application, which is similar between all examples
+- [infra](infra) - stores the definition of your infrastructure
+ - [cdk.json](infra/cdk.json) - tells the CDK Toolkit how to execute your app
+ - [CdkApp](./infra/src/main/java/cdk/CdkApp.java) - bootstraps your stack, taking AWS `account` and `region` as input
+ - [CdkStack](./infra/src/main/java/cdk/CdkStack.java) - defines the Lambda function to be deployed as well as API Gateway for it.
+
+It is a [Maven](https://maven.apache.org/) based project, so you can open this project with any Maven compatible Java IDE to build and run tests.
+
+
+## Deploy the sample application
+
+The minimum to deploy the app should be
+```bash
+cdk deploy
+```
+
+If you're running CDK for the first time, you'll need to first run the bootstrap command:
+```bash
+cdk bootstrap
+```
+
+## Useful commands
+
+* `mvn package` compile and run tests
+* `cdk synth` emits the synthesized CloudFormation template
+* `cdk deploy` deploy this stack to your default AWS account/region
+* `cdk diff` compare deployed stack with current state
+* `cdk docs` open CDK documentation

+# Powertools for AWS Lambda (Java) - Core Utilities Example with Gradle
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Serverless Application Model](https://aws.amazon.com/serverless/sam/) with
+[Gradle](https://gradle.org/) running the build. This example is configured for Java 11 only; in order to use a newer version, check out the Gradle
+configuration guide [in the main project README](../../../README.md).
+
+You can also use `sam init` to create a new Gradle-powered Powertools application - choose to use the **AWS Quick Start Templates**,
+and then **Hello World Example with Powertools for AWS Lambda**, **Java 17** runtime, and finally **gradle**.
+
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+SAM uses [template.yaml](template.yaml) to define the application's AWS resources.
+This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+The build of the project is managed by Gradle, and configured in [build.gradle](build.gradle).
+
+## Deploy the sample application
+To get started, you can use the Gradle wrapper to bootstrap Gradle and run the build:
+
+```bash
+./gradlew build
+```
+
+Once this is done to deploy the example, check out the instructions for getting started with SAM in
+[the examples directory](../../README.md)
+
+## Additional notes
+
+You can watch the trace information or log information using the SAM CLI:
+```bash
+# Tail the logs
+sam logs --tail $MY_STACK
+
+# Tail the traces
+sam traces --tail
+```

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.

+# Powertools for AWS Lambda (Kotlin) - Core Utilities Example
+
+This project demonstrates the Lambda for Powertools Kotlin module deployed using [Serverless Application Model](https://aws.amazon.com/serverless/sam/) with
+[Gradle](https://gradle.org/) running the build. This example is configured for Java 11 only; in order to use a newer version, check out the Gradle
+configuration guide [in the main project README](../../../README.md).
+
+You can also use `sam init` to create a new Gradle-powered Powertools application - choose to use the **AWS Quick Start Templates**,
+and then **Hello World Example with Powertools for AWS Lambda**, **Java 17** runtime, and finally **gradle**.
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+SAM uses [template.yaml](template.yaml) to define the application's AWS resources.
+This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+The build of the project is managed by Gradle, and configured in [build.gradle.kts](build.gradle.kts)
+.
+
+## Deploy the sample application
+To get started, you can use the included template with SAM to run the build and deploy to your AWS environment:
+
+```bash
+sam build && sam deploy --guided
+```
+
+Once this is done to deploy the example, check out the instructions for getting started with SAM in
+[the examples directory](../../README.md)
+
+## Additional notes
+
+You can watch the trace information or log information using the SAM CLI:
+```bash
+# Tail the logs
+sam logs --tail $MY_STACK
+
+# Tail the traces
+sam traces --tail
+```

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.
+#
+# You can find Gradle at https://github.com/gradle/gradle/.

+# Powertools for AWS Lambda (Java) - Core Utilities Example with Bazel
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Serverless Application Model](https://aws.amazon.com/serverless/sam/) and built with Bazel.
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+
+SAM uses [template.yaml](template.yaml) to define the application's AWS resources. This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+## Deploy the sample application
+
+To deploy the example, check out the instructions for getting started with SAM in [the examples directory](../../README.md)
+
+## Build and deploy
+
+```bash
+# Build the application
+bazel build //:powertools_sam_deploy.jar
+
+# Deploy the application
+sam deploy --guided
+```
+
+## Local testing
+
+```bash
+# Build the application
+bazel build //:powertools_sam_deploy.jar
+
+# Test a single function locally
+sam local invoke HelloWorldFunction --event events/event.json
+
+# Start the local API
+sam local start-api
+
+# Test the API endpoints
+curl http://127.0.0.1:3000/hello
+curl http://127.0.0.1:3000/hellostream
+```
+
+## Additional notes
+
+You can watch the trace information or log information using the SAM CLI:
+
+```bash
+# Tail the logs
+sam logs --tail $MY_STACK
+
+# Tail the traces
+sam traces --tail
+```
+
+### Pinning Maven versions
+
+To ensure reproducible builds, you can pin Maven dependency versions:
+
+```bash
+# Generate lock file for reproducible builds
+bazel run @maven//:pin
+```
+
+This creates `maven_install.json` which locks dependency versions and should be committed to version control.

+# Powertools for AWS Lambda (Java) - Core Utilities Example with SAM on GraalVM
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Serverless Application Model](https://aws.amazon.com/serverless/sam/) running as a GraalVM native image.
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+
+- SAM uses [template.yaml](template.yaml) to define the application's AWS resources.
+ This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+- Set the environment to use GraalVM
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+```
+
+## Build the sample application
+
+- Build the Docker image that will be used as the environment for SAM build:
+
+```shell
+docker build --platform linux/amd64 . -t powertools-examples-core-sam-graalvm
+```
+
+- Build the SAM project using the docker image
+
+```shell
+sam build --use-container --build-image powertools-examples-core-sam-graalvm
+```
+
+#### [Optional] Building with -SNAPSHOT versions of PowerTools
+
+- If you are testing the example with a -SNAPSHOT version of PowerTools, the maven build inside the docker image will fail. This is because the -SNAPSHOT version of the PowerTools library that you are working on is still not available in maven central/snapshot repository.
+ To get around this, follow these steps:
+ - Create the native image using the `docker` command below on your development machine. The native image is created in the `target` directory.
+ - `` docker run --platform linux/amd64 -it -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 powertools-examples-core-sam-graalvm mvn clean -Pnative-image package -DskipTests ``
+ - Edit the [`Makefile`](Makefile) remove this line
+ - `mvn clean package -P native-image`
+ - Build the SAM project using the docker image
+ - `sam build --use-container --build-image powertools-examples-core-sam-graalvm`
+
+## Deploy the sample application
+
+- SAM deploy
+
+```shell
+sam deploy
+```
+
+To deploy the example, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Additional notes
+
+You can watch the trace information or log information using the SAM CLI:
+
+```bash
+# Tail the logs
+sam logs --tail $MY_STACK
+
+# Tail the traces
+sam traces --tail
+```

+# Powertools for AWS Lambda (Java) - Core Utilities Example with SAM
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Serverless Application Model](https://aws.amazon.com/serverless/sam/).
+
+For general information on the deployed example itself, you can refer to the parent [README](../README.md)
+
+## Configuration
+SAM uses [template.yaml](template.yaml) to define the application's AWS resources.
+This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+## Deploy the sample application
+To deploy the example, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Additional notes
+
+You can watch the trace information or log information using the SAM CLI:
+```bash
+# Tail the logs
+sam logs --tail $MY_STACK
+
+# Tail the traces
+sam traces --tail
+```

+# Powertools for AWS Lambda (Java) - Core Utilities Example with Serverless Framework
+
+This project demonstrates the Lambda for Powertools Java module deployed using [Serverless Framework](https://www.serverless.com/framework).
+For general information on the deployed example itself, you can refer to the parent [README](../README.md).
+To install Serverless Framework if you don't have it yet, you can follow the [Getting Started Guide](https://www.serverless.com/framework/docs/getting-started).
+
+## Configuration
+Serverless Framework uses [serverless.yml](serverless.yml) to define the application's AWS resources.
+This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+It is a [Maven](https://maven.apache.org/) based project, so you can open this project with any Maven compatible Java IDE to build and run tests.
+
+
+## Deploy the sample application
+
+To deploy the app, simply run the following commands:
+```bash
+mvn package && sls deploy
+```
+
+## Useful commands
+
+Deploy a single function
+```bash
+sls deploy function -f hello
+```

+# Powertools for AWS Lambda (Java) - Idempotency Example with SAM on GraalVM
+
+This project contains an example of a Lambda function using the idempotency module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/idempotency/).
+
+The example exposes a HTTP POST endpoint. When the user sends the address of a webpage to it, the endpoint fetches the contents of the URL and returns them to the user.
+
+Have a look at [App.java](src/main/java/helloworld/App.java) for the full details.
+
+## Build the sample application
+
+> [!NOTE]
+> Building AWS Lambda packages on macOS (ARM64/Intel) for deployment on AWS Lambda (Linux x86_64 or ARM64) will result in incompatible binary dependencies that cause import errors at runtime.
+
+Choose the appropriate build method based on your operating system:
+
+### Build locally using Docker
+
+Recommended for macOS and Windows users: Cross-compile using Docker to match target platform of Lambda:
+
+```shell
+docker build --platform linux/amd64 . -t powertools-examples-idempotency-sam-graalvm
+docker run --platform linux/amd64 -it -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 powertools-examples-idempotency-sam-graalvm mvn clean -Pnative-image package -DskipTests
+sam build --use-container --build-image powertools-examples-idempotency-sam-graalvm
+```
+
+**Note**: The Docker run command mounts your local Maven cache (`~/.m2`) and builds the native binary with SNAPSHOT support, then SAM packages the pre-built binary.
+
+### Build on native OS
+
+For Linux users with GraalVM installed:
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+mvn clean -Pnative-image package -DskipTests
+sam build
+```
+
+## Deploy the sample application
+
+```shell
+sam deploy
+```
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting started with SAM in [the examples directory](../../README.md)
+
+## Test the application
+
+```bash
+curl -X POST https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/helloidem/ -H "Content-Type: application/json" -d '{"address": "https://checkip.amazonaws.com"}'
+```
+
+this should return the contents of the webpage, for instance:
+
+```json
+{ "message": "hello world", "location": "123.123.123.1" }
+```
+
+- First call will execute the handleRequest normally, and store the response in the idempotency table (Look into DynamoDB)
+- Second call (and next ones) will retrieve from the cache (if cache is enabled, which is by default) or from the store, the handler won't be called. Until the expiration happens (by default 1 hour).
+
+Check out [App.java](src/main/java/helloworld/App.java) to see how it works!

+# Powertools for AWS Lambda (Java) - Idempotency Example
+
+This project contains an example of Lambda function using the idempotency module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/idempotency/).
+The example exposes a HTTP POST endpoint. When the user sends the address of a webpage to it, the endpoint fetches the contents of the URL and returns them to the user:
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../README.md)
+
+## Test the application
+
+```bash
+ curl -X POST https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/helloidem/ -H "Content-Type: application/json" -d '{"address": "https://checkip.amazonaws.com"}'
+```
+
+this should return the contents of the webpage, for instance:
+```json
+{ "message": "hello world", "location": "123.123.123.1" }
+```
+
+Check out [App.java](src/main/java/helloworld/App.java) to see how it works!

+# Powertools for AWS Lambda (Java) - Kafka Example
+
+This project demonstrates how to use Powertools for AWS Lambda (Java) to deserialize Kafka Lambda events directly into strongly typed Kafka ConsumerRecords<K, V> using different serialization formats.
+
+## Overview
+
+The example showcases automatic deserialization of Kafka Lambda events into ConsumerRecords using three formats:
+- JSON - Using standard JSON serialization
+- Avro - Using Apache Avro schema-based serialization
+- Protobuf - Using Google Protocol Buffers serialization
+
+Each format has its own Lambda function handler that demonstrates how to use the `@Deserialization` annotation with the appropriate `DeserializationType`, eliminating the need to handle complex deserialization logic manually.
+
+## Build and Deploy
+
+### Prerequisites
+- [AWS SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html)
+- Java 11+
+- Maven
+
+### Build
+
+```bash
+# Build the application
+sam build
+```
+
+### Deploy
+
+```bash
+# Deploy the application to AWS
+sam deploy --guided
+```
+
+During the guided deployment, you'll be prompted to provide values for required parameters. After deployment, SAM will output the ARNs of the deployed Lambda functions.
+
+### Build with Different Serialization Formats
+
+The project includes Maven profiles to build with different serialization formats:
+
+```bash
+# Build with JSON only (no Avro or Protobuf)
+mvn clean package -P base
+
+# Build with Avro only
+mvn clean package -P avro-only
+
+# Build with Protobuf only
+mvn clean package -P protobuf-only
+
+# Build with all formats (default)
+mvn clean package -P full
+```
+
+## Testing
+
+The `events` directory contains sample events for each serialization format:
+- `kafka-json-event.json` - Sample event with JSON-serialized products
+- `kafka-avro-event.json` - Sample event with Avro-serialized products
+- `kafka-protobuf-event.json` - Sample event with Protobuf-serialized products
+
+You can use these events to test the Lambda functions:
+
+```bash
+# Test the JSON deserialization function
+sam local invoke JsonDeserializationFunction --event events/kafka-json-event.json
+
+# Test the Avro deserialization function
+sam local invoke AvroDeserializationFunction --event events/kafka-avro-event.json
+
+# Test the Protobuf deserialization function
+sam local invoke ProtobufDeserializationFunction --event events/kafka-protobuf-event.json
+```
+
+## Sample Generator Tool
+
+The project includes a tool to generate sample JSON, Avro, and Protobuf serialized data. See the [tools/README.md](tools/README.md) for more information.

+# Kafka Sample Generator Tool
+
+This tool generates base64-encoded serialized products for testing the Kafka consumer functions with different serialization formats.
+
+## Supported Formats
+
+- **JSON**: Generates base64-encoded JSON serialized products
+- **Avro**: Generates base64-encoded Avro serialized products
+- **Protobuf**: Generates base64-encoded Protobuf serialized products
+
+## Usage
+
+Run the following Maven commands from this directory:
+
+```bash
+# Generate Avro and Protobuf classes from schemas
+mvn generate-sources
+
+# Compile the code
+mvn compile
+```
+
+### Generate JSON Samples
+
+```bash
+# Run the JSON sample generator
+mvn exec:java -Dexec.mainClass="org.demo.kafka.tools.GenerateJsonSamples"
+```
+
+The tool will output base64-encoded values for JSON products that can be used in `../events/kafka-json-event.json`.
+
+### Generate Avro Samples
+
+```bash
+# Run the Avro sample generator
+mvn exec:java -Dexec.mainClass="org.demo.kafka.tools.GenerateAvroSamples"
+```
+
+The tool will output base64-encoded values for Avro products that can be used in `../events/kafka-avro-event.json`.
+
+### Generate Protobuf Samples
+
+```bash
+# Run the Protobuf sample generator
+mvn exec:java -Dexec.mainClass="org.demo.kafka.tools.GenerateProtobufSamples"
+```
+
+The tool will output base64-encoded values for Protobuf products that can be used in `../events/kafka-protobuf-event.json`. This generator creates samples with and without Confluent message-indexes to test different serialization scenarios.
+
+## Output
+
+Each generator produces:
+
+1. Three different products (Laptop, Smartphone, Headphones)
+2. An integer key (42) and one entry with a nullish key to test for edge-cases
+3. A complete sample event structure that can be used directly for testing
+
+The Protobuf generators additionally create samples with different Confluent message-index formats:
+- Standard protobuf (no message indexes)
+- Simple message index (single 0 byte)
+- Complex message index (length-prefixed array)
+
+For more information about Confluent Schema Registry serialization formats and wire format specifications, see the [Confluent documentation](https://docs.confluent.io/platform/current/schema-registry/fundamentals/serdes-develop/index.html#wire-format).
+
+## Example
+
+After generating the samples, you can copy the output into the respective event files:
+
+- `../events/kafka-json-event.json` for JSON samples
+- `../events/kafka-avro-event.json` for Avro samples
+- `../events/kafka-protobuf-event.json` for Protobuf samples
+
+These event files can then be used to test the Lambda functions with the appropriate deserializer.

+# Powertools for AWS Lambda (Java) - Parameters Example with SAM on GraalVM
+
+This project contains an example of Lambda function using the parameters module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/parameters/).
+
+The example uses the [SSM Parameter Store](https://docs.powertools.aws.dev/lambda/java/utilities/parameters/#ssm-parameter-store)
+and the [Secrets Manager](https://docs.powertools.aws.dev/lambda/java/utilities/parameters/#secrets-manager) to inject
+runtime parameters into the application.
+Have a look at [ParametersFunction.java](src/main/java/org/demo/parameters/ParametersFunction.java) for the full details.
+
+## Configuration
+
+- SAM uses [template.yaml](template.yaml) to define the application's AWS resources.
+ This file defines the Lambda function to be deployed as well as API Gateway for it.
+
+- Set the environment to use GraalVM
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+```
+
+## Build the sample application
+
+- Build the Docker image that will be used as the environment for SAM build:
+
+```shell
+docker build --platform linux/amd64 . -t powertools-examples-parameters-sam-graalvm
+```
+
+- Build the SAM project using the docker image
+
+```shell
+sam build --use-container --build-image powertools-examples-parameters-sam-graalvm
+```
+
+#### [Optional] Building with -SNAPSHOT versions of PowerTools
+
+- If you are testing the example with a -SNAPSHOT version of PowerTools, the maven build inside the docker image will fail. This is because the -SNAPSHOT version of the PowerTools library that you are working on is still not available in maven central/snapshot repository.
+ To get around this, follow these steps:
+ - Create the native image using the `docker` command below on your development machine. The native image is created in the `target` directory.
+ - `` docker run --platform linux/amd64 -it -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 powertools-examples-parameters-sam-graalvm mvn clean -Pnative-image package -DskipTests ``
+ - Edit the [`Makefile`](Makefile) remove this line
+ - `mvn clean package -P native-image`
+ - Build the SAM project using the docker image
+ - `sam build --use-container --build-image powertools-examples-parameters-sam-graalvm`
+
+## Deploy the sample application
+
+- SAM deploy
+
+```shell
+sam deploy
+```
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Test the application
+
+First, hit the URL of the application. You can do this with curl or your browser:
+
+```bash
+ curl https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/params/
+```
+You will get your IP address back. The contents of the logs will be more interesting, and show you the values
+of the parameters injected into the handler:
+
+```bash
+sam logs --stack-name $MY_STACK_NAME --tail
+```
+
+```json
+{
+ ...
+ "thread": "main",
+ "level": "INFO",
+ "loggerName": "org.demo.parameters.ParametersFunction",
+ "message": "secretjsonobj=MyObject{id=23443, code='hk38543oj24kn796kp67bkb234gkj679l68'}\n",
+ ...
+}
+```

+# Powertools for AWS Lambda (Java) - Parameters Example
+
+This project contains an example of Lambda function using the parameters module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/parameters/).
+
+The example uses the [SSM Parameter Store](https://docs.powertools.aws.dev/lambda/java/utilities/parameters/#ssm-parameter-store)
+and the [Secrets Manager](https://docs.powertools.aws.dev/lambda/java/utilities/parameters/#secrets-manager) to inject
+runtime parameters into the application.
+Have a look at [ParametersFunction.java](src/main/java/org/demo/parameters/ParametersFunction.java) for the full details.
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Test the application
+
+First, hit the URL of the application. You can do this with curl or your browser:
+
+```bash
+ curl https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/params/
+```
+You will get your IP address back. The contents of the logs will be more interesting, and show you the values
+of the parameters injected into the handler:
+
+```bash
+sam logs --stack-name $MY_STACK_NAME --tail
+```
+
+```json
+{
+ ...
+ "thread": "main",
+ "level": "INFO",
+ "loggerName": "org.demo.parameters.ParametersFunction",
+ "message": "secretjsonobj=MyObject{id=23443, code='hk38543oj24kn796kp67bkb234gkj679l68'}\n",
+ ...
+}
+```

+# Powertools for AWS Lambda (Java) - Serialization Example
+
+This project contains an example of Lambda function using the serialization utilities module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/latest/utilities/serialization/).
+
+The project contains two `RequestHandler`s -
+
+* [APIGatewayRequestDeserializationFunction](src/main/java/org/demo/serialization/APIGatewayRequestDeserializationFunction.java) - Uses the serialization library to deserialize an API Gateway request body
+* [SQSEventDeserializationFunction](src/main/java/org/demo/serialization/SQSEventDeserializationFunction.java) - Uses the serialization library to deserialize an SQS message body
+
+In both cases, the output of the serialized message will be printed to the function logs. The message format
+in JSON looks like this:
+
+```json
+{
+ "id":1234,
+ "name":"product",
+ "price":42
+}
+```
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Configuration
+
+- Set the environment to use GraalVM
+
+```shell
+export JAVA_HOME=<path to GraalVM>
+```
+
+## Build the sample application
+
+- Build the Docker image that will be used as the environment for SAM build:
+
+```shell
+docker build --platform linux/amd64 . -t powertools-examples-serialization-sam-graalvm
+```
+
+- Build the SAM project using the docker image
+
+```shell
+sam build --use-container --build-image powertools-examples-serialization-sam-graalvm
+```
+
+#### [Optional] Building with -SNAPSHOT versions of PowerTools
+
+- If you are testing the example with a -SNAPSHOT version of PowerTools, the maven build inside the docker image will fail. This is because the -SNAPSHOT version of the PowerTools library that you are working on is still not available in maven central/snapshot repository.
+ To get around this, follow these steps:
+ - Create the native image using the `docker` command below on your development machine. The native image is created in the `target` directory.
+ - `` docker run --platform linux/amd64 -it -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 powertools-examples-serialization-sam-graalvm mvn clean -Pnative-image package -DskipTests ``
+ - Edit the [`Makefile`](Makefile) remove this line
+ - `mvn clean package -P native-image`
+ - Build the SAM project using the docker image
+ - `sam build --use-container --build-image powertools-examples-serialization-sam-graalvm`
+
+
+## Test the application
+
+### 1. API Gateway Endpoint
+
+To test the HTTP endpoint, we can post a product to the test URL:
+
+```bash
+curl -X POST https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/product/ -H "Content-Type: application/json" -d '{"id": 1234, "name": "product", "price": 42}'
+```
+
+The result will indicate that the handler has successfully deserialized the request body:
+
+```
+Received request for productId: 1234
+```
+
+If we look at the logs using `sam logs --tail --stack-name $MY_STACK`, we will see the full deserialized request:
+
+```json
+{
+ ...
+ "level": "INFO",
+ "loggerName": "org.demo.serialization.APIGatewayRequestDeserializationFunction",
+ "message": "product=Product{id=1234, name='product', price=42.0}\n",
+ ...
+}
+```
+
+### 2. SQS Queue
+For the SQS handler, we have to send a request to our queue. We can either construct the Queue URL (see below), or
+find it from the SQS section of the AWS console.
+
+```bash
+ aws sqs send-message --queue-url "https://sqs.[REGION].amazonaws.com/[ACCOUNT-ID]/sqs-event-deserialization-queue" --message-body '{"id": 1234, "name": "product", "price": 123}'
+```
+
+Here we can find the message by filtering through the logs for messages that have come back from our SQS handler:
+
+```bash
+sam logs --tail --stack-name $MY_STACK --filter SQS
+```
+
+```bash
+ {
+ ...
+ "level": "INFO",
+ "loggerName": "org.demo.serialization.SQSEventDeserializationFunction",
+ "message": "products=[Product{id=1234, name='product', price=42.0}]\n",
+ ...
+}
+
+```

+# Powertools for AWS Lambda (Java) - Serialization Example
+
+This project contains an example of Lambda function using the serialization utilities module of Powertools for AWS Lambda (Java). For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/serialization/).
+
+The project contains two `RequestHandler`s -
+
+* [APIGatewayRequestDeserializationFunction](src/main/java/org/demo/serialization/APIGatewayRequestDeserializationFunction.java) - Uses the serialization library to deserialize an API Gateway request body
+* [SQSEventDeserializationFunction](src/main/java/org/demo/serialization/SQSEventDeserializationFunction.java) - Uses the serialization library to deserialize an SQS message body
+
+In both cases, the output of the serialized message will be printed to the function logs. The message format
+in JSON looks like this:
+
+```json
+{
+ "id":1234,
+ "name":"product",
+ "price":42
+}
+```
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../../README.md)
+
+## Test the application
+
+### 1. API Gateway Endpoint
+
+To test the HTTP endpoint, we can post a product to the test URL:
+
+```bash
+curl -X POST https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/product/ -H "Content-Type: application/json" -d '{"id": 1234, "name": "product", "price": 42}'
+```
+
+The result will indicate that the handler has successfully deserialized the request body:
+
+```
+Received request for productId: 1234
+```
+
+If we look at the logs using `sam logs --tail --stack-name $MY_STACK`, we will see the full deserialized request:
+
+```json
+{
+ ...
+ "level": "INFO",
+ "loggerName": "org.demo.serialization.APIGatewayRequestDeserializationFunction",
+ "message": "product=Product{id=1234, name='product', price=42.0}\n",
+ ...
+}
+```
+
+### 2. SQS Queue
+For the SQS handler, we have to send a request to our queue. We can either construct the Queue URL (see below), or
+find it from the SQS section of the AWS console.
+
+```bash
+ aws sqs send-message --queue-url "https://sqs.[REGION].amazonaws.com/[ACCOUNT-ID]/sqs-event-deserialization-queue" --message-body '{"id": 1234, "name": "product", "price": 123}'
+```
+
+Here we can find the message by filtering through the logs for messages that have come back from our SQS handler:
+
+```bash
+sam logs --tail --stack-name $MY_STACK --filter SQS
+```
+
+```bash
+ {
+ ...
+ "level": "INFO",
+ "loggerName": "org.demo.serialization.SQSEventDeserializationFunction",
+ "message": "products=[Product{id=1234, name='product', price=42.0}]\n",
+ ...
+}
+
+```

+# Powertools for AWS Lambda (Java) - Validation Example
+
+This project contains an example of Lambda function using the validation module of Powertools for AWS Lambda (Java).
+For more information on this module, please refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/validation/).
+
+The handler [InboundValidation](src/main/java/org/demo/validation/InboundValidation.java) validates incoming HTTP requests
+received from the API gateway against [schema.json](src/main/resources/schema.json).
+
+## Deploy the sample application
+
+This sample is based on Serverless Application Model (SAM). To deploy it, check out the instructions for getting
+started with SAM in [the examples directory](../README.md)
+
+## Test the application
+
+To test the validation, we can POST a JSON object shaped like our schema:
+```bash
+ curl -X POST https://[REST-API-ID].execute-api.[REGION].amazonaws.com/Prod/hello/ -H "Content-Type: application/json" -d '{"id": 123,"name":"The Hitchhikers Guide to the Galaxy","price":10.99}'
+```
+
+If we break the schema - for instance, by removing one of the compulsory fields,
+we will get an error back from our API and will see a `ValidationException` in the logs:
+
+```bash
+ sam logs --tail --stack-name $MY_STACK
+```

+## End-to-end tests
+This module is internal and meant to be used for end-to-end (E2E) testing of Powertools for AWS Lambda (Java).
+
+__Prerequisites__:
+- An AWS account is needed as well as a local environment able to reach this account
+([credentials](https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/credentials.html)).
+- [Java 11+](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html)
+- [Docker](https://docs.docker.com/engine/install/)
+
+To execute the E2E tests, use the following command: `export JAVA_VERSION=11 && mvn clean verify -Pe2e`
+
+### Under the hood
+This module leverages the following components:
+- AWS CDK to define the infrastructure and synthesize a CloudFormation template and the assets (lambda function packages)
+- The AWS S3 SDK to push the assets on S3
+- The AWS CloudFormation SDK to deploy the template

+## Idempotency
+Refer to the [documentation](https://docs.powertools.aws.dev/lambda-java/utilities/idempotency/) for details on how to use this module in your Lambda function.
+
+### Contributing
+This module provides a persistence layer with a built-in store using DynamoDB.
+To unit test it, we use [DynamoDB Local](https://docs.aws.amazon.com/fr_fr/amazondynamodb/latest/developerguide/DynamoDBLocal.html) which depends on sqlite.
+You may encounter the following issue on Apple M1 chips:
+```
+com.almworks.sqlite4java.SQLiteException: [-91] cannot load library: java.lang.UnsatisfiedLinkError: native-libs/libsqlite4java-osx-1.0.392.dylib: dlopen(native-libs/libsqlite4java-osx-1.0.392.dylib, 1): no suitable image found. Did find:
+native-libs/libsqlite4java-osx-1.0.392.dylib: no matching architecture in universal wrapper
+```
+
+In such case, try with another JDK. See [stackoverflow](https://stackoverflow.com/questions/66635424/dynamodb-local-setup-on-m1-apple-silicon-mac) and this [issue](https://github.com/aws-samples/aws-dynamodb-examples/issues/22) for more info.
+We'll update the dependencies as soon as it will be solved.

+/**
+ * Idempotency provides both a configuration and a functional API for implementing idempotent workloads.
+ *
+ * <p>This class is thread-safe. All operations delegate to the underlying persistence store
+ * which handles concurrent access safely.</p>
+ *
+ * <h2>Configuration</h2>
+ * <p>Configure the persistence layer and idempotency settings before your handler executes (e.g. in constructor):</p>
+ * <pre>{@code
+ * Idempotency.config()
+ * .withPersistenceStore(persistenceStore)
+ * .withConfig(idempotencyConfig)
+ * .configure();
+ * }</pre>
+ *
+ * <h2>Functional API</h2>
+ * <p>Make methods idempotent without AspectJ annotations. Generic return types (e.g., {@code Map<String, Object>},
+ * {@code List<Product>}) are supported via Jackson {@link TypeReference}.</p>
+ *
+ * <p><strong>Important:</strong> Always call {@link #registerLambdaContext(Context)}
+ * at the start of your handler to enable proper timeout handling.</p>
+ *
+ * <p>Example usage with Function (single parameter):</p>
+ * <pre>{@code
+ * public Basket handleRequest(Product input, Context context) {
+ * Idempotency.registerLambdaContext(context);
+ * return Idempotency.makeIdempotent(this::processProduct, input, Basket.class);
+ * }
+ *
+ * private Basket processProduct(Product product) {
+ * // business logic
+ * }
+ * }</pre>
+ *
+ * <p>Example usage with Supplier (multi-parameter methods):</p>
+ * <pre>{@code
+ * public String handleRequest(SQSEvent event, Context context) {
+ * Idempotency.registerLambdaContext(context);
+ * return Idempotency.makeIdempotent(
+ * event.getRecords().get(0).getBody(),
+ * () -> processPayment(orderId, amount, currency),
+ * String.class
+ * );
+ * }
+ * }</pre>
+ *
+ * <p>When different methods use the same payload as idempotency key, use explicit function names
+ * to differentiate between them:</p>
+ * <pre>{@code
+ * // Different methods, same payload
+ * Idempotency.makeIdempotent("processPayment", orderId,
+ * () -> processPayment(orderId), String.class);
+ *
+ * Idempotency.makeIdempotent("refundPayment", orderId,
+ * () -> refundPayment(orderId), String.class);
+ * }</pre>
+ *
+ * @see #config()
+ * @see #registerLambdaContext(Context)
+ * @see #makeIdempotent(Object, Supplier, Class)
+ * @see #makeIdempotent(String, Object, Supplier, Class)
+ * @see #makeIdempotent(Function, Object, Class)

+/**
+ * A Log4j2 appender that buffers log events by AWS X-Ray trace ID for optimized Lambda logging.
+ *
+ * <p>This appender is designed specifically for AWS Lambda functions to reduce log ingestion
+ * by buffering lower-level logs and only outputting them when errors occur, preserving
+ * full context for troubleshooting while minimizing routine log volume.
+ *
+ * <h3>Key Features:</h3>
+ * <ul>
+ * <li><strong>Trace-based buffering:</strong> Groups logs by AWS X-Ray trace ID</li>
+ * <li><strong>Selective output:</strong> Only buffers logs at or below configured verbosity level</li>
+ * <li><strong>Auto-flush on errors:</strong> Automatically outputs buffered logs when ERROR/FATAL events occur</li>
+ * <li><strong>Memory management:</strong> Prevents memory leaks with configurable buffer size limits</li>
+ * <li><strong>Overflow protection:</strong> Warns when logs are discarded due to buffer limits</li>
+ * </ul>
+ *
+ * <h3>Configuration Example:</h3>
+ * <pre>{@code
+ * <BufferingAppender name="BufferedAppender"
+ * bufferAtVerbosity="DEBUG"
+ * maxBytes="20480"
+ * flushOnErrorLog="true">
+ * <AppenderRef ref="ConsoleAppender"/>
+ * </BufferingAppender>
+ * }</pre>
+ *
+ * <h3>Configuration Parameters:</h3>
+ * <ul>
+ * <li><strong>bufferAtVerbosity:</strong> Log level to buffer (default: DEBUG). Logs at this level and below are buffered</li>
+ * <li><strong>maxBytes:</strong> Maximum buffer size in bytes per trace ID (default: 20480)</li>
+ * <li><strong>flushOnErrorLog:</strong> Whether to flush buffer on ERROR/FATAL logs (default: true)</li>
+ * </ul>
+ *
+ * <h3>Behavior:</h3>
+ * <ul>
+ * <li>During Lambda INIT phase (no trace ID): logs are output directly</li>
+ * <li>During Lambda execution (with trace ID): logs are buffered or output based on level</li>
+ * <li>When buffer overflows: oldest logs are discarded and a warning is logged</li>
+ * <li>On Lambda completion: buffer is auto-cleared when used with {@code @Logging} annotation</li>
+ * </ul>
+ *
+ * @see software.amazon.lambda.powertools.logging.PowertoolsLogging#flushBuffer()

+/**
+ * A Logback appender that buffers log events by AWS X-Ray trace ID for optimized Lambda logging.
+ *
+ * <p>This appender is designed specifically for AWS Lambda functions to reduce log ingestion
+ * by buffering lower-level logs and only outputting them when errors occur, preserving
+ * full context for troubleshooting while minimizing routine log volume.
+ *
+ * <h3>Key Features:</h3>
+ * <ul>
+ * <li><strong>Trace-based buffering:</strong> Groups logs by AWS X-Ray trace ID</li>
+ * <li><strong>Selective output:</strong> Only buffers logs at or below configured verbosity level</li>
+ * <li><strong>Auto-flush on errors:</strong> Automatically outputs buffered logs when ERROR/FATAL events occur</li>
+ * <li><strong>Memory management:</strong> Prevents memory leaks with configurable buffer size limits</li>
+ * <li><strong>Overflow protection:</strong> Warns when logs are discarded due to buffer limits</li>
+ * </ul>
+ *
+ * <h3>Configuration Example:</h3>
+ * <pre>{@code
+ * <appender name="BufferedAppender" class="software.amazon.lambda.powertools.logging.logback.BufferingAppender">
+ * <bufferAtVerbosity>DEBUG</bufferAtVerbosity>
+ * <maxBytes>20480</maxBytes>
+ * <flushOnErrorLog>true</flushOnErrorLog>
+ * <appender-ref ref="ConsoleAppender"/>
+ * </appender>
+ * }</pre>
+ *
+ * <h3>Configuration Parameters:</h3>
+ * <ul>
+ * <li><strong>bufferAtVerbosity:</strong> Log level to buffer (default: DEBUG). Logs at this level and below are buffered</li>
+ * <li><strong>maxBytes:</strong> Maximum buffer size in bytes per trace ID (default: 20480)</li>
+ * <li><strong>flushOnErrorLog:</strong> Whether to flush buffer on ERROR/FATAL logs (default: true)</li>
+ * </ul>
+ *
+ * <h3>Behavior:</h3>
+ * <ul>
+ * <li>During Lambda INIT phase (no trace ID): logs are output directly</li>
+ * <li>During Lambda execution (with trace ID): logs are buffered or output based on level</li>
+ * <li>When buffer overflows: oldest logs are discarded and a warning is logged</li>
+ * <li>On Lambda completion: buffer is auto-cleared when used with {@code @Logging} annotation</li>
+ * </ul>
+ *
+ * @see software.amazon.lambda.powertools.logging.PowertoolsLogging#flushBuffer()

+/**
+ * <p>
+ * Simple implementation of {@link Logger} that sends all enabled log messages,
+ * for all defined loggers, to the console ({@code System.err}). The following
+ * system properties are supported to configure the behavior of this logger:
+ *
+ *
+ * <ul>
+ * <li><code>org.slf4j.simpleLogger.logFile</code> - The output target which can
+ * be the <em>path</em> to a file, or the special values "System.out" and
+ * "System.err". Default is "System.err".</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.cacheOutputStream</code> - If the output
+ * target is set to "System.out" or "System.err" (see preceding entry), by
+ * default, logs will be output to the latest value referenced by
+ * <code>System.out/err</code> variables. By setting this parameter to true, the
+ * output stream will be cached, i.e. assigned once at initialization time and
+ * re-used independently of the current value referenced by
+ * <code>System.out/err</code>.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.defaultLogLevel</code> - Default log level
+ * for all instances of SimpleLogger. Must be one of ("trace", "debug", "info",
+ * "warn", "error" or "off"). If not specified, defaults to "info".</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.log.<em>a.b.c</em></code> - Logging detail
+ * level for a SimpleLogger instance named "a.b.c". Right-side value must be one
+ * of "trace", "debug", "info", "warn", "error" or "off". When a SimpleLogger
+ * named "a.b.c" is initialized, its level is assigned from this property. If
+ * unspecified, the level of nearest parent logger will be used, and if none is
+ * set, then the value specified by
+ * <code>org.slf4j.simpleLogger.defaultLogLevel</code> will be used.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.showDateTime</code> - Set to
+ * <code>true</code> if you want the current date and time to be included in
+ * output messages. Default is <code>false</code></li>
+ *
+ * <li><code>org.slf4j.simpleLogger.dateTimeFormat</code> - The date and time
+ * format to be used in the output messages. The pattern describing the date and
+ * time format is defined by <a href=
+ * "http://docs.oracle.com/javase/1.5.0/docs/api/java/text/SimpleDateFormat.html">
+ * <code>SimpleDateFormat</code></a>. If the format is not specified or is
+ * invalid, the number of milliseconds since start up will be output.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.showThreadName</code> -Set to
+ * <code>true</code> if you want to output the current thread name. Defaults to
+ * <code>true</code>.</li>
+ *
+ * <li>(since version 1.7.33 and 2.0.0-alpha6) <code>org.slf4j.simpleLogger.showThreadId</code> -
+ * If you would like to output the current thread id, then set to
+ * <code>true</code>. Defaults to <code>false</code>.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.showLogName</code> - Set to
+ * <code>true</code> if you want the Logger instance name to be included in
+ * output messages. Defaults to <code>true</code>.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.showShortLogName</code> - Set to
+ * <code>true</code> if you want the last component of the name to be included
+ * in output messages. Defaults to <code>false</code>.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.levelInBrackets</code> - Should the level
+ * string be output in brackets? Defaults to <code>false</code>.</li>
+ *
+ * <li><code>org.slf4j.simpleLogger.warnLevelString</code> - The string value
+ * output for the warn level. Defaults to <code>WARN</code>.</li>
+ *
+ * </ul>
+ *
+ * <p>
+ * In addition to looking for system properties with the names specified above,
+ * this implementation also checks for a class loader resource named
+ * <code>"simplelogger.properties"</code>, and includes any matching definitions
+ * from this resource (if it exists).
+ *
+ *
+ * <p>
+ * With no configuration, the default output includes the relative time in
+ * milliseconds, thread name, the level, logger name, and the message followed
+ * by the line separator for the host. In log4j terms it amounts to the "%r [%t]
+ * %level %logger - %m%n" pattern.
+ *
+ * <p>
+ * Sample output follows.
+ *
+ *
+ * <pre>
+ * 176 [main] INFO examples.Sort - Populating an array of 2 elements in reverse order.
+ * 225 [main] INFO examples.SortAlgo - Entered the sort method.
+ * 304 [main] INFO examples.SortAlgo - Dump of integer array:
+ * 317 [main] INFO examples.SortAlgo - Element [0] = 0
+ * 331 [main] INFO examples.SortAlgo - Element [1] = 1
+ * 343 [main] INFO examples.Sort - The next log statement should be an error message.
+ * 346 [main] ERROR examples.SortAlgo - Tried to dump an uninitialized array.
+ * at org.log4j.examples.SortAlgo.dump(SortAlgo.java:58)
+ * at org.log4j.examples.Sort.main(Sort.java:64)
+ * 467 [main] INFO examples.Sort - Exiting main method.
+ * </pre>
+ *
+ * <p>
+ * This implementation is heavily inspired by
+ * <a href="http://commons.apache.org/logging/">Apache Commons Logging</a>'s
+ * SimpleLog.

+ * {@code FlushMetrics} is used to signal that the annotated Lambda handler method should be
+ * extended with Metrics flushing functionality. Will have no effect when used on a method that is not a Lambda handler.
+ *
+ * <p>{@code FlushMetrics} allows users to asynchronously create Amazon
+ * CloudWatch metrics by using the CloudWatch <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format_Specification.html">Embedded Metrics Format</a>.
+ * {@code FlushMetrics} manages the life-cycle and configuration of Metrics to simplify the user experience when used with AWS Lambda.
+ *
+ * <p>{@code FlushMetrics} should be used with the handleRequest method of a class
+ * which implements either
+ * {@code com.amazonaws.services.lambda.runtime.RequestHandler} or
+ * {@code com.amazonaws.services.lambda.runtime.RequestStreamHandler}.</p>
+ *
+ * <p>{@code FlushMetrics} creates Amazon CloudWatch custom metrics. You can find
+ * pricing information on the <a href="https://aws.amazon.com/cloudwatch/pricing/">CloudWatch pricing documentation</a> page.</p>
+ *
+ * <p>To enable creation of custom metrics for cold starts you can add {@code @FlushMetrics(captureColdStart = true)}.
+ * </br>This will create a metric with the key {@code "ColdStart"} and the unit type {@code COUNT}.
+ * </p>
+ *
+ * <p>To raise exception if no metrics are emitted, use {@code @FlushMetrics(raiseOnEmptyMetrics = true)}.
+ * </br>This will create an exception if no metrics are emitted. By default its value is set to false.
+ * </p>
+ *
+ * <p>By default the service name associated with metrics created will be
+ * "service_undefined". This can be overridden with the environment variable {@code POWERTOOLS_SERVICE_NAME}
+ * or the annotation variable {@code @FlushMetrics(service = "Service Name")}.
+ * If both are specified then the value of the annotation variable will be used.</p>
+ *
+ * <p>A namespace must be specified for metrics. This can be set with the environment variable {@code POWERTOOLS_METRICS_NAMESPACE}
+ * or the annotation variable {@code @FlushMetrics(namespace = "Namespace")}. If not specified, an IllegalStateException will be thrown.
+ * If both are specified then the value of the annotation variable will be used.</p>
+ *
+ * <p>You can specify a custom function name with {@code @FlushMetrics(functionName = "MyFunction")}.
+ * If specified, this will be used instead of the function name from the Lambda context.

/**
- * {@code Metrics} is used to signal that the annotated method should be
- * extended with Metrics functionality.
- *
- * <p>{@code Metrics} allows users to asynchronously create Amazon
- * CloudWatch metrics by using the CloudWatch <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Embedded_Metric_Format_Specification.html">Embedded Metrics Format</a>.
- * {@code Metrics} manages the life-cycle of the MetricsLogger class,
- * to simplify the user experience when used with AWS Lambda.
- *
- * <p>{@code Metrics} should be used with the handleRequest method of a class
- * which implements either
- * {@code com.amazonaws.services.lambda.runtime.RequestHandler} or
- * {@code com.amazonaws.services.lambda.runtime.RequestStreamHandler}.</p>
- *
- * <p>{@code Metrics} creates Amazon CloudWatch custom metrics. You can find
- * pricing information on the <a href="https://aws.amazon.com/cloudwatch/pricing/">CloudWatch pricing documentation</a> page.</p>
- *
- * <p>To enable creation of custom metrics for cold starts you can add {@code @Metrics(captureColdStart = true)}.
- * </br>This will create a metric with the key {@code "ColdStart"} and the unit type {@code COUNT}.
- * </p>
- *
- * <p>To raise exception if no metrics are emitted, use {@code @Metrics(raiseOnEmptyMetrics = true)}.
- * </br>This will create a create a exception of type {@link ValidationException}. By default its value is set to false.
- * </p>
- *
- * <p>By default the service name associated with metrics created will be
- * "service_undefined". This can be overridden with the environment variable {@code POWERTOOLS_SERVICE_NAME}
- * or the annotation variable {@code @Metrics(service = "Service Name")}.
- * If both are specified then the value of the annotation variable will be used.</p>
- *
- * <p>By default the namespace associated with metrics created will be "aws-embedded-metrics".
- * This can be overridden with the environment variable {@code POWERTOOLS_METRICS_NAMESPACE}
- * or the annotation variable {@code @Metrics(namespace = "Namespace")}.
- * If both are specified then the value of the annotation variable will be used.</p>
+ * Interface for metrics implementations.
+ * This interface is used to collect metrics in the Lambda function.
+ * It provides methods to add metrics, dimensions, and metadata.
