> > @fhan688 is there any bug we want to fix in this patch? > > Yes. The bug is that MOR compaction rollback planning can be overly conservative and leave compaction-produced files behind after the later delta commits are no longer present. > > This patch keeps the old base-file-only behavior when later delta commits still exist, but allows full cleanup of the compaction instant when no later delta commits remain. The requested-compaction changes are to keep rollback/restore timeline-only for REQUESTED instants, so they do not generate file-level rollback work. didn't get it yet, can you revert the optimization code make make the smallest change for the fix. -- This is an automated message from the Apache Git Service.
