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

             Summary: New rule: SemiJoinToCorrelateRule (SemiJoin => LogicalCorrelate)
                 Key: CALCITE-2621
                 URL: https://issues.apache.org/jira/browse/CALCITE-2621
             Project: Calcite
          Issue Type: Improvement
            Reporter: Ruben Quesada Lopez
            Assignee: Julian Hyde
             Fix For: 1.18.0


Similarly to JoinToCorrelateRule, in some contexts it might be interesting to transform a
SemiJoin into a LogicalCorrelate, for this purpose a SemiJoinToCorrelateRule will be needed.
