             Summary: Extend min/max filter for inequality subquery for other use cases
                 Key: IMPALA-10869
                 URL: https://issues.apache.org/jira/browse/IMPALA-10869
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Qifan Chen


Min/max filtering for inequality scalar subqueries have been addressed in the patch for IMPALA-3040. It is desirable to extend the work for other use cases as follows.

1.  When the subquery returns more than one row;
2. When the subquery returns one row through: a) 1 row through a limit clause, b) one group only.
