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

             Summary: HashJoin don't build hash tables when probe side is empty.
                 Key: DRILL-6755
                 URL: https://issues.apache.org/jira/browse/DRILL-6755
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Timothy Farkas
            Assignee: Boaz Ben-Zvi


Currently when doing an Inner or a Right join we still build hashtables when 
the probe side is empty. A performance optimization would be to not build them.
