Dear devs,
This is the first meeting after feature freeze of Flink 1.20. I'd like to share the information synced in the meeting. - Feature Freeze We have announced the feature freeze of 1.20 at June 15. Finally, we have 13 completed features. Meanwhile, 3 features were moved to the next release, but none of them are must-have for 1.20. - Blockers: - FLINK-35629 - Performance regression in stringRead and stringWrite - We haven't found the root cause yet, but Zakelly will try JMH 1.19 to exclude the impact of environment change. - FLINK-35587 - job fails with "The read buffer is null in credit-based input channel" on TPC-DS 10TB benchmark - This is a serious bug that influence our credit-base network protocol. Junrui has identified the commit that caused the problem. Weijie will investigate it with the highest priority. - Cutting release branch We are planning to cut the release branch on next Monday (June 24). For the convenience of testing, we decided to out *rc0* release a few days after cut-branch, please note that it is only for testing purpose and is not intended to be a final release. We'll make announcement separately in the dev mailing list for both of them. - Release Testing We have created an umbrella JIRA[1] for release testing of 1.20. please check and complete the documentation and test instruction of your new feature and mark the related JIRA issue in the 1.20 release wiki page [2] before we start testing, which would be quite helpful for other developers to validate your features. - Sync meeting[3]: Due to the time conflict of some RM, we decided to advance the start time of release sync meeting by *half an hour*. The next meeting is 06/25/2024 9.30am (UTC+2) and 3.30pm (UTC+8), please feel free to join us. Lastly, we encourage attendees to fill out the topics to be discussed at the bottom of 1.20 wiki page[2] a day in advance, to make it easier for everyone to understand the background of the topics, thanks!
