    @amansinha100 thanks for sharing the information.  Got your point. I think your propose
on  [CALCITE-1048](https://issues.apache.org/jira/browse/CALCITE-1048) is possible. Since
[CALCITE-794](https://issues.apache.org/jira/browse/CALCITE-794) has completed at version
1.6 ,it seems there's a more perfect solution( to get the least max number of all the rels
of the RelSubSet). But due to Drill's Caclite version is still based on 1.4 , I support your
current temp solution. Only wonder that whether the explicitly searched RelNode's (such as
DrillAggregateRel) maxRowCount can represent the best RelNode's maxRowCount ?
