Subject [jira] [Created] (HBASE-14524) Short-circuit comparison of rows in CellComparator
Date Wed, 30 Sep 2015 12:11:04 GMT
Lars Francke created HBASE-14524:

             Summary: Short-circuit comparison of rows in CellComparator
                 Key: HBASE-14524
                 URL: https://issues.apache.org/jira/browse/HBASE-14524
             Project: HBase
          Issue Type: Improvement
            Reporter: Lars Francke
            Assignee: Lars Francke
            Priority: Minor

{{CellComparator#compareRows}} compares two rows. For Scans and Gets these objects can sometimes
be exactly the same object.

I see this (without fully understanding all everything that's going on) for the first cell
in each row.

In these circumstances I think it makes sense to short-circuit the comparison (not do a byte
comparison and class cast checks) and bail out early if the objects are identical.
