> For right outer join, values of the left key will be filled with nulls if it can't match the value of the right key, so `nullOrdering` of the left key can't be guaranteed. We should output right key order.
> For full outer join, neither left key nor right key guarantees `nullOrdering`. We should not output any ordering.
