> For now simple JOIN requests like:
> {noformat}
> SELECT * FROM integers FULL OUTER JOIN integers2 ON integers.i=integers2.k ORDER BY i
> {noformat}
> can be planned only through MergeJoin or NestedLoopJoin it would be useful to extend
it with CNLJ too. Starting point : FilterSpoolMergeToSortedIndexSpoolRule#onMatch
