             Summary: Support joining back to data table row from local index when query condition
involves leading columns local index
                 Key: PHOENIX-1015
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1015
             Project: Phoenix
          Issue Type: Sub-task
            Reporter: rajeshbabu
            Assignee: rajeshbabu


When a query involves more columns to project than columns in index and query condition involves
leading columns in local index then first we can get matching rowkeys from local index table
and then get the required columns from data table. In local index both data region and index
region co-reside in the same RS, we can call get on data region to get the missing columns
in the index, without any n/w overhead. So it's efficient.
