------------------------------------

             Summary: Support block encoding based on knowing set of column qualifiers up
front
                 Key: HBASE-12883
                 URL: https://issues.apache.org/jira/browse/HBASE-12883
             Project: HBase
          Issue Type: Bug
            Reporter: James Taylor


Phoenix knows up front the set of column qualifiers a row will have. We could likely get some
good compression with little CPU based on this by having a block encoding scheme that leverages
this information. It could be made non-Phoenix specific by identifying the set of column qualifiers
through meta data to the block encoder.
