Sophie Blee-Goldman resolved KAFKA-8215.
----------------------------------------
Resolution: Fixed
> Limit memory usage of RocksDB
> -----------------------------
>
> Key: KAFKA-8215
> URL: https://issues.apache.org/jira/browse/KAFKA-8215
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Sophie Blee-Goldman
> Priority: Major
> Fix For: 2.3.0
>
>
> The memory usage of Streams is currently unbounded in part because of
> RocksDB, which consumes memory on a per-instance basis. Each instance (ie
> each persistent state store) will have its own write buffer, index blocks,
> and block cache. The size of these can be configured individually, but there
> is currently no way for a Streams app to limit the total memory available
> across instances.
