[jira] [Created] (HBASE-13999) Improve storefile split performance by creating daughter reference files concurrently

Hari Krishna Dara created HBASE-13999:
-----------------------------------------

             Summary: Improve storefile split performance by creating daughter reference files concurrently
                 Key: HBASE-13999
                 URL: https://issues.apache.org/jira/browse/HBASE-13999
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.98.12
            Reporter: Hari Krishna Dara
            Assignee: Hari Krishna Dara
            Priority: Minor


The fix for HBASE-13959 improves the concurrency of region split operation, and also identifies another optimization by extending the concurrency to the creation of individual reference files. This jira aims to do just that! Since creation of reference files take time in the order of 300 to 400ms, this has the potential of reducing the split time by as much in most common scenarios.
