> 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.
