Hi, devs, This is the fourth meeting for Flink 2.1 release cycle. I'd like to share the information synced in the meeting.
- Feature Freeze It is worth noting that there are only 2 weeks left until the feature freeze time(June 21, 2025), and developers need to pay attention to the feature freeze time. - Features: So far we've had 16 FLIPs/features, and five FLIPs have been completed in 2.1. Regarding the remaining 11 FLIPs, 8 FLIPs are confirmed to be completed in 2.1, and the status of the other three is uncertain. The progress of two very important FLIP-486 & FLIP-521 is still zero, there are some concerns the effort could be ready for the feature freeze of 2.1. I will confirm it with the corresponding contributor. - CI: So far, we have four unstable cases and none blocker issues. all of which have created jira issues： 1. https://issues.apache.org/jira/browse/FLINK-37703: This was an occasional unstable case caused by a test-dependent HDFS, and we found a community contributor to locate it 2. https://issues.apache.org/jira/browse/FLINK-37822: Piotr will fix it. 3. https://issues.apache.org/jira/browse/FLINK-37701: We found Piotr to fix it. 4. https://issues.apache.org/jira/browse/FLINK-37842: This is a problem with the test case itself. No contributor has been found yet. We are still monitoring it. In addition, we have recently frequently encountered 502 & 503 Proxy Errors in Maven deploy. The response given by ASF infra is hardware problem and is in the process of migrating data to a replacement server. For details, see: https://issues.apache.org/jira/browse/INFRA-26874 - Benchmark Since May 19, some serde-related performance regressions have occurred, see the issue for details. We need a volunteer to locate the root cause by reproducing it locally. Since it only occurs on JDK11, Zakelly believes it may not be a problem, so it is not a blocker now. 1. https://issues.apache.org/jira/browse/FLINK-37826 - Sync meeting[3]: As code freeze is approaching, release-sync is adjusted from two weeks to once a week, so the next meeting time is 06/011/2025, Please feel free to join us[2]! Lastly, we encourage attendees to fill out the topics to be discussed at the bottom of 2.1 wiki page[1] a day in advance, to make it easier for everyone to understand the background of the topics, thanks!
