Bill Bejeck commented on KAFKA-9145:
------------------------------------
As part of the 2.7.0 release process, I'm clearing the fix version field. When
we have a PR for this ticket we can update the fix version at that point.
> AbstractCoordinator should respect retry backoff between rebalances

> Key: KAFKA-9145
> URL: https://issues.apache.org/jira/browse/KAFKA-9145
> Project: Kafka
> Issue Type: Improvement
> Components: consumer, KafkaConnect
> Reporter: Jason Gustafson
> Priority: Major
> Fix For: 2.7.0
>
>
> We hit a situation where the connect worker seems to have been requesting
> group rejoins repeatedly for some reason. In theory the same thing could
> happen to the consumer if a user repeatedly changes the subscribed topics in
> a tight loop. Currently AbstractCoordinator would not backoff in these cases
> because the rebalances may all be completing successfully. It probably makes
> sense to enforce a minimum time between locally triggered rebalances in order
> to avoid overloading the broker with repeated group rebalances.
