dajac opened a new pull request #10878: URL: https://github.com/apache/kafka/pull/10878
While investigating https://issues.apache.org/jira/browse/KAFKA-12896, I have noticed that the leader was always sending the same subscribed partitions but not always in the order. The group coordinator compares the provided subscription with the store subscription based on their bytes representation. So if the subscribed partitions are not in the same order, the group coordinator would consider that they are different and rebalance the group. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
