Hi Adam, Thanks for the proposed revision to your KIP (https://cwiki.apache.org/confluence/pages/diffpagesbyversion.action?pageId=74684836&selectedPageVersions=77&selectedPageVersions=74)
in response to the concern pointed out during code review (https://github.com/apache/kafka/pull/5527#issuecomment-505137962) We should have a brief discussion thread (here) in the mailing list to make sure everyone who wants to gets a chance to consider the modification to the design. Thanks, -John
