> Currently, EnumerableMergeJoin supports INNER, SEMI, and ANTI join.
> The goal of this ticket is to support also LEFT join (which should be a combination of INNER join results + ANTI join results with a NULL on the right).
> LEFT EnumerableMergeJoin should maintain the order of the left-hand-side of the join.
