# [DRILL-8209](https://issues.apache.org/jira/browse/DRILL-8209): Introduce rule for converting join with distinct input to semi-join ## Description 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. Adding rule that converts join to semi-join if the right side has distinct columns. Fixed cost and row count computation for semi-join. ## Documentation NA ## Testing Unit tests pass -- This is an automated message from the Apache Git Service.
