[jira] [Created] (HBASE-8403) Allow column family to be declared as containing only fixed length KeyValues to improve scan performance

James Taylor created HBASE-8403:
-----------------------------------

             Summary: Allow column family to be declared as containing only fixed length KeyValues to improve scan performance
                 Key: HBASE-8403
                 URL: https://issues.apache.org/jira/browse/HBASE-8403
             Project: HBase
          Issue Type: New Feature
          Components: Performance
            Reporter: James Taylor


HBase scan performance could be improved in cases where a column family is known to have only fixed length KeyValues (and perhaps in addition non nullable). A custom block encoding could leverage this to dramatically improve scan performance.
