Thanks for the efforts so far with pushing for 1.11.3. I'd like to provide a mid-week update on how we're looking with all the pending blockers and backports:
*Blockers**:* Currently all blockers either have an open PR, or have been merged. I'll highlight below the blockers *that still require reviewing efforts for them to move forward:* - [FLINK-19909] Flink application in attach mode could not terminate when the only job is canceled. PR: https://github.com/apache/flink/pull/13911 - [FLINK-19717] SourceReaderBase.pollNext may return END_OF_INPUT if SplitReader.fetch throws. PR: https://github.com/apache/flink/pull/13776 The above PRs currently have no reviews at all yet. They seem to already have designated reviewers. *Backports:* - FLIP-27 robustness improvement backports: Stephan is currently working on backporting several FLIP-27 changes. There are no PRs yet for the backported changes. - DataStreamUtils.collect() refactorings backport: Steven Wu mentioned to backport this, but AFAIK this isn't assigned to anyone yet. *ETAs*: I'd like to request ETAs for the remaining backports, to prevent a creep in the scope of this bugfix release. We already have Flink users that would benefit from fixes that have been merged to release-1.11 already, so technically speaking the backports should be considered "nice-to-have" (to the best of my knowledge of the changes) and could potentially be moved to a follow-up 1.11.4. Most notably, the Stateful Functions project is already waiting on Flink 1.11.3 to address critical recovery issues (please see the StateFun 2.2.1 release discussion thread [1]). @Stephan Ewen <se...@apache.org> @Becket Qin <becket....@gmail.com> could you provide an ETA for the FLIP-27 backports? It would help to get a better estimate to decide how we proceed here.
