----------------------------------
Labels: new-streams-runtime-should-fix (was: )
> Do not create standbys for those revoking active tasks if it is not stateful
> ----------------------------------------------------------------------------

> Key: KAFKA-10263
> URL: https://issues.apache.org/jira/browse/KAFKA-10263
> Project: Kafka
> Issue Type: Improvement
> Reporter: Guozhang Wang
> Assignee: Guozhang Wang
> Priority: Major
> Labels: new-streams-runtime-should-fix
>
> Today in StreamsPartitionAssignor, if an intended active tasks is not yet
> revoked from the old owner we would not give it to the newly assigned owner,
> but instead we would assign it as a standby task to the new owner to let it
> start restoring a bit early.
> However, if that task is not stateful, then there's no point trying to let it
> restore at all. This should be avoided in the assignor.
