             Summary: consider split improvements for stripe compactions
                 Key: HBASE-7819
                 URL: https://issues.apache.org/jira/browse/HBASE-7819
             Project: HBase
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


>From discussions in HBASE-7667, and in person.
Files cannot be "just moved" to new regions because of snapshot reliance on that not happening (correct me if I'm wrong).
However, obviously we don't need compaction after split if we have files with specific ranges, so we could handle this somehow.
On the other hand, if you have 6 fixed stripes, and split into 3 and 3, you'd want to go back to 6 stripes, so when you do compaction in one of the 3 you will want special handling to do it.
