    Description

      Currently, EnumerableMergeJoin only supports INNER joins. The goal of this ticket is to improve this join operator in order to support SEMI joins too.

      Note: RelMdCollation#mergeJoin will need to be modified too: in case of SEMI join, it must return just the leftCollations.
