HOTFIX: cherry-pick KAFKA-13563 compatiblity fix into 3.1#723
Merged
Conversation
…ache#12244) (apache#12259) This is a cherrypick commit of 3.1. Another way of fixing KAFKA-13563 other than apache#11631. Instead of letting the consumer to always try to discover coordinator in pool with either mode (subscribe / assign), we defer the clearance of discover future upon committing async only. More specifically, under manual assign mode, there are only three places where we need the coordinator: commitAsync (both by the consumer itself or triggered by caller), this is where we want to fix. commitSync, which we already try to re-discovery coordinator. committed (both by the consumer itself based on reset policy, or triggered by caller), which we already try to re-discovery coordinator. The benefits are that for manual assign mode that does not try to trigger any of the above three, then we never would be discovering coordinator. The original fix in apache#11631 would let the consumer to discover coordinator even if none of the above operations are required.
