morningman opened a new pull request #2558: [Compaction] Support compact only one rowset URL: https://github.com/apache/incubator-doris/pull/2558 Support compaction operation to compact only one rowset. After the modification, the last rowset of the tablet will also be compacted. At the same time, we added a `segments_overlap_pb` field to the rowset meta. Used to describe whether the segment data in the rowset overlaps. This field is set by `rowset_writer`. Initially UNKNOWN for compatibility with existing data. In addition, the version hash of the rowset generated after compaction is directly set to the version hash of last rowset participating in compaction, to ensure that the tablet's version hash remains unchanged after compaction.
