--------------------------------------
Summary: 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
Fix For: 2.5.0
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.
