Kafka encoder example in Python API section of the book should not copy incoming data #2695
Description
Is this a bug, feature request, or feedback?
Bug
What is the current behavior?
The Kafka encoder example in the Python API section of the book returns a copy of the incoming data rather than returning the data itself. This is unnecessary.
This came up here: #2691 (comment)
What is the expected behavior?
The Kafka encoder example should return the incoming data directly.
