Mickael Maison commented on KAFKA-17411:
----------------------------------------
It seems the implementation of KIP-1035 is not complete yet so I'll move it out
of the 4.1.0 release plan. Let me know if my understanding is not correct.
> StateStore managed changelog offsets
> ------------------------------------

> Key: KAFKA-17411
> URL: https://issues.apache.org/jira/browse/KAFKA-17411
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Reporter: Nicholas Telford
> Assignee: Nicholas Telford
> Priority: Major
> Labels: kip
>
> Kafka Streams currently tracks the changelog offsets that correspond to local
> state in per-Task {{.checkpoint}} files, that are maintained by the internal
> Streams engine, independently of the StateStore implementation being used.
> Allowing StateStores to instead manage their changelog offsets themselves
> enables them to optimise the storage and management of both the changelog
> offsets _and_ the corresponding data.
