Sriram Subramanian updated KAFKA-671:
-------------------------------------
Attachment: outOfMemFix-v2.patch
- Ignore the changes in bin and system tests
- this change is cleaner and a lot safer.
- the data is now an mutable map
- we just cache the topicpartition - message size in producer request
- we clear the map after handling the request
- the toString implementation of produceRequest uses the cached map instead
of the data
- the byteBuffer in RequestChannel.Request is now made private and is set to
null after deserialization.
- update test cases to work with these changes
- I will be updating the thread with how the heap characteristics look before
and after this change.
> DelayedProduce requests should not hold full producer request data
