Hi everyone, I would like to start the discussion for KIP-1362: Add a rollback-compatible storage format option for KRaft migration.
KIP: https://cwiki.apache.org/confluence/spaces/KAFKA/pages/440303727/KIP-1362+Add+a+rollback-compatible+storage+format+option+for+KRaft+migration Jira: https://issues.apache.org/jira/browse/KAFKA-20762 PR/reference implementation: https://github.com/apache/kafka/pull/22751 In summary: this KIP proposes closing a current gap, where the ability to do rollback of an ongoing KRaft migration breaks when cluster member nodes are replaced. The proposed solution is to add a CLI flag to the storage formatting tool that causes the resulting storage to not break when rolled back. I'm looking forward to feedback on this proposal.
