Stanilovsky Evgeny created IGNITE-14810:
-------------------------------------------

             Summary: Calcite. SimpleJOIN with f1=f2 cannot be planned with CNLJ.
                 Key: IGNITE-14810
                 URL: https://issues.apache.org/jira/browse/IGNITE-14810
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Stanilovsky Evgeny


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
