----------------------------------

             Summary: Release the memory back into MemoryPool
                 Key: KAFKA-13188
                 URL: https://issues.apache.org/jira/browse/KAFKA-13188
             Project: Kafka
          Issue Type: Improvement
            Reporter: Lucas Wang


Tushar made a [hotfix change|https://github.com/linkedin/kafka/pull/186] to the linkedin/kafka repo hosting apache kafka 2.4.

The change is about releasing memory back to the MemoryPool for the kafka consumer, and his benchmark showed significant improvement in terms of the memory graduating from Young Gen and promoted to Old Gen.

Given the benefit, the change should also be added trunk.
