> 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.
