Subject [jira] [Created] (HBASE-8418) Caching KeyValue.getRowLength() to improve scan performance
Date Wed, 24 Apr 2013 15:09:16 GMT
Matteo Bertozzi created HBASE-8418:

             Summary: Caching KeyValue.getRowLength() to improve scan performance
                 Key: HBASE-8418
                 URL: https://issues.apache.org/jira/browse/HBASE-8418
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Matteo Bertozzi
            Assignee: Matteo Bertozzi
            Priority: Minor

Looking at the profile seems that Bytes.toShort() is called a lot.
the calls are in ScanQueryMatcher.match() and KeyValue.KeyComparator.compare()

getKeyLength() is already cached, but getRowLength() is not.
