Hi dev, I'm happy to serve the role of the release manager for Apache Spark 4.3. Since this is the first release we followed the new policy of 3 months cadence, there might be some confusion/concern and I need your help and understanding. (Thanks in advance for your help and patience!)
I'm collecting the projects the workstream has been happening on Apache Spark 4.3 (branch-4.x at this moment) - I'll be focusing on SPIP, but please give the head-up for your project which has partially landed to Apache Spark 4.3 and you are close to the finish line. For the projects you are unlikely to complete before branch cut (loosely plus 1-2 weeks after branch cut), you are encouraged to have a flag to disable the partial change to take effect in Apache Spark 4.3, and postpone the finish line to Apache Spark 4.4. The delay of missing Apache Spark 4.3 wouldn't be long for you thanks to 3 months release cadence, and "be open to postpone the schedule for the project" is a key success factor for faster release. Thanks for your understanding! I'll update the versioning policy page to reflect the expected schedule of Apache Spark 4.3.0 release. Please post here for any questions and voices/feedback. Thanks!
