             Summary: Skip family comparing when compare cells inner the store
                 Key: HBASE-27788
                 URL: https://issues.apache.org/jira/browse/HBASE-27788
             Project: HBase
          Issue Type: Improvement
          Components: Performance
            Reporter: Zheng Wang
            Assignee: Zheng Wang


Currently we use CellComparatorImpl to compare cells, it compare row first, 
then family, then qulifier and so on.

If the comparing inner the store, the families are always equal(unless the 
familyLength is zero for special purpose), so this step could be skipped for 
better performance.
