Hi Yi, Thank you for creating this FLIP! The introduction of the Application entity significantly enhances the observability and manageability of user logic, especially benefiting batch workloads. This is truly excellent work!
However, I have a compatibility concern and would appreciate your clarification. In the “Archiving Directory Structure” section, I noticed that the directory structure has been changed. If users have configured a persistent external path for jobmanager.archive.fs.dir, will their existing archives become unreadable after this change? Will the implementation of this FLIP maintain backward compatibility with previously archived job data?
