@Dandandan @alamb I guess the purpose of this ticket is try to introduce some method to skip the `partial` aggregation if the `partial` aggregation can not reduce the row count(for high cardinality aggregation), correct ? In Snowflake and Teradata, they call this adaptive partial aggregation. I'm not sure for TPC-H queries whether this will help or not, but for some TPC-DS queries, this is quite useful. -- This is an automated message from the Apache Git Service.
