      Description

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

      Note: RelMdCollation#mergeJoin will need to be modified too: in case of ANTI join, it must return just the leftCollations. UPDATE: this has been done already as part of CALCITE-3833.
