Feng Honghua created HBASE-10487:
------------------------------------

             Summary: Avoid allocating new KeyValue for appended kvs which don't have existing(old)
values
                 Key: HBASE-10487
                 URL: https://issues.apache.org/jira/browse/HBASE-10487
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Feng Honghua
            Assignee: Feng Honghua


in HRegion.append, a new KeyValue will be allocated no matter there is existing kv for the
appended cell, we can improve here by avoiding the allocating of new KeyValue for kv without
existing value by reusing the passed-in kv and only update its timestamp to 'now'(its original
timestamp is latest, so can be updated)
