Date Mon, 10 Dec 2012 10:33:21 GMT
Julian Zhou created HBASE-7312:
----------------------------------

             Summary: Flatten the invoking to the compare/match methods of KeyValue.java
                 Key: HBASE-7312
                 URL: https://issues.apache.org/jira/browse/HBASE-7312
             Project: HBase
          Issue Type: Improvement
          Components: Performance
    Affects Versions: 0.94.3, 0.94.2
            Reporter: Julian Zhou
            Priority: Minor
             Fix For: 0.94.3, 0.94.2


Invoking to some methods in KeyValue may could be short cut. Like KeyComparator.compareColumns
-> KeyValue.compareColumns, 
KVComparator.compareColumns -> KeyComparator.compareColumns -> KeyValue.compareColumns,
KeyComparator.compareRows -> Bytes.compareTo,
KVComparator.matchingRows -> Bytes.equals,
MetaKeyComparator.compareRowid -> Bytes.compareTo, ... etc.
Will apply the change, the test the performance difference.
