[jira] [Created] (DRILL-8209) Introduce rule for converting join with distinct input to semi-join

Vova Vysotskyi created DRILL-8209:
-------------------------------------

             Summary: Introduce rule for converting join with distinct input to semi-join
                 Key: DRILL-8209
                 URL: https://issues.apache.org/jira/browse/DRILL-8209
             Project: Apache Drill
          Issue Type: Sub-task
            Reporter: Vova Vysotskyi
            Assignee: Vova Vysotskyi


Newer Calcite changed the order of applying rules. AggregateRemoveRule is applied before SemiJoinRule, so SemiJoinRule cannot be applied later, since aggregate is pruned from planning.
