Before this patch, the tombstone can be deleted if its revision is equal compacted revision. It causes that the watch subscriber won't get this DELETE event. Based on Compact API[1], we should keep tombstone revision if it's not less than the compaction revision. > CompactionRequest compacts the key-value store up to a given revision. > All superseded keys with a revision less than the compaction revision > will be removed.
