Chris Egerton commented on KAFKA-14837: --------------------------------------- [~hudeqi] have you tried adjusting the {{refresh.groups.interval.seconds}} property for the connector? That controls how often it checks for new/dead consumer groups. You can user a higher value if you'd like the rebalances to be less frequent. > The MirrorCheckPointConnector of MM2 will rebalance frequently, when the > source cluster group is many more and changes frequently (but the list of > configured synchronous group does not change) > ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ > > Key: KAFKA-14837 > URL: https://issues.apache.org/jira/browse/KAFKA-14837 > Project: Kafka > Issue Type: Improvement > Components: KafkaConnect, mirrormaker > Affects Versions: 3.3.2 > Reporter: hudeqi > Assignee: hudeqi > Priority: Major > > In practice, I found that when I configure a mirror checkpoint connector, > because the source cluster has a large number of group or the number of group > under a topic changes frequently, the connector will frequently rebalance > between its tasks, although there is no change in the synchronized group list > of the configuration. > I don't think connector should rebalance frequently in this case to affect > group synchronization tasks without any group changes. -- This message was sent by Atlassian Jira (v8.20.10#820010)
