[jira] [Created] (DRILL-646) Generate broadcast-inner plans for MergeJoin and HashJoin

Aman Sinha created DRILL-646:
--------------------------------

             Summary: Generate broadcast-inner plans for MergeJoin and HashJoin
                 Key: DRILL-646
                 URL: https://issues.apache.org/jira/browse/DRILL-646
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Aman Sinha
            Assignee: Aman Sinha


We want to be able to generate MergeJoin and HashJoin plans where the inner child is broadcast and outer child can be left as-is  (i.e ANY distribution is acceptable).  Such plans will be compared by cost with plans where both children are hash-distributed or any new plans that we add.
