// Package experimental is a collection of experimental features that might
// have some rough edges to them. Housing experimental features in this package
// results in a user accessing these APIs as `experimental.Foo`, thereby making
// it explicit that the feature is experimental and using them in production
// code is at their own risk.
//
// All APIs in this package are experimental.

// WithBufferPool returns a grpc.DialOption that configures the use of bufferPool
// for parsing incoming messages on a grpc.ClientConn, and for temporary buffers
// when marshaling outgoing messages. By default, mem.DefaultBufferPool is used,
// and this option only exists to provide alternative buffer pool implementations
// to the client, such as more optimized size allocations etc. However, the
// default buffer pool is already tuned to account for many different use-cases.
//
// Note: The following options will interfere with the buffer pool because they
// require a fully materialized buffer instead of a sequence of buffers:
// EnableTracing, and binary logging. In such cases, materializing the buffer
// will generate a lot of garbage, reducing the overall benefit from using a
