Another idea is that what if we alter this plan to count distinct specific ``` 05)--------AggregateExec: mode=FinalPartitioned, gby=[alias1@0 as alias1], aggr=[] ``` ``` 05)--------AggregateExec: mode=Final, gby=[alias1@0 as alias1], aggr=[], count_distinct_specialized=true ``` And, we return the sum of group keys from each partition, it should be the same result as the output of `02)--AggregateExec: mode=Final, gby=[], aggr=[count(alias1)]`. -- This is an automated message from the Apache Git Service.
