---------------------------------
Summary: in-memory state store memory issue
Key: KAFKA-5393
URL: https://issues.apache.org/jira/browse/KAFKA-5393
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.10.2.1
Reporter: Kevin Chen
Attachments: Screen Shot 2017-06-06 at 9.45.42 AM.png
We are running 2 kafka stream instance that use low level Processor API, and we
are using in-memory state store.
When we upgrade instance A, which will move all the tasks to instance B, and
re-balance between the 2 after A is back up and running.
But the problem is that, even after the re-balance, the memory in instance A
did not drop to the previous level(the load is about the same).
see the screen shot below.
