Subject [jira] [Created] (HBASE-9956) Remove keyLength cache from KeyValue
Date Tue, 12 Nov 2013 01:02:22 GMT

------------------------------------

             Summary: Remove keyLength cache from KeyValue
                 Key: HBASE-9956
                 URL: https://issues.apache.org/jira/browse/HBASE-9956
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl
            Priority: Minor
         Attachments: 9935-0.94.txt

See discussion in HBASE-9935. Currently KeyValue caches the keyLength in order to avoid decoding
the key length in getKeyLength() repeatedly.
Benchmarking outside of a profiler revealed no improvement from that cache (and a sampling
profiler also does not indicate getKeyLength() as a performance issue).
Along with this there's also a slight fix in ScanQueryMatcher.
