Hi all, There are some critical bugs related to ZK migration, so I’d like to open a discussion for the 3.9.3 release.
KAFKA-20960: Block ZK-to-KRaft migration finalization until brokers re-register (merged) https://github.com/apache/kafka/commit/ea11d59ecda2ec57be0f1ef83a554ef5d3b82770 KAFKA-21142: Fix partition creation when handling snapshot delta during migration (merged) https://github.com/apache/kafka/commit/daebfbd9b37c913937d5adfc2e493fe825e3da3a KAFKA-21062: Handle BADVERSION on /migration writes (under review) https://github.com/apache/kafka/pull/23639 My sense is that ZK migration is the only official way to encourage users to get into KRaft, so keeping it working is a strong reason to do a release. I haven’t finished reviewing the last one yet, but it would be good to make sure the release will happen. Otherwise, my tokens will be totally wasted :) Any thoughts?
