[jira] [Created] (HBASE-6913) Implement new data block encoding algorithm that combines the advantages of FAST_DIFF and DIFF_KEY

             Summary: Implement new data block encoding algorithm that combines the advantages of FAST_DIFF and DIFF_KEY
                 Key: HBASE-6913
                 URL: https://issues.apache.org/jira/browse/HBASE-6913
             Project: HBase
          Issue Type: Improvement
            Reporter: Mikhail Bautin


We have noticed that both FAST_DIFF and DIFF_KEY encoding algorithms have some drawbacks in that they don't take advantage of certain types of redundancies in keys/values. We need to implement a new algorithm that combines the most useful properties of these two algorithms, and specifically unit-test that various types of redundancies are removed.
