Some more info - We probably don't want this to be the default plan for GROUP BY in multi stage. Default should be the existing 2 phase GROUP BY (leaf + exchange + intermediary). Just want support (preferably via hint where we know what we are doing) for this to be there for testing / tuning high cardinality GROUP BY on multi stage engine. There could be a performance benefit by avoiding the partial aggregates at the leaf layer for such a scenario. -- This is an automated message from the Apache Git Service.
