   Thanks, @Apache9 . The main advantage here is that the first compaction after split can be a minor compaction instead of old major compaction, because only reference files should be compacted before the next split. In HBASE-26422, I described the compaction after splitting using HFileLink.
   It also makes move hfiles between regions of the same table possible. Then the compaction is light weight, since it need not to read and rewrite the referred files.
