godfrey he updated FLINK-12610:
-------------------------------
Description:
This issue aims to introduce planner rules about aggregate, rules include:
1. {{AggregateCalcMergeRule}}, that recognizes {{Aggregate}} on top of a
{{Calc}} and if possible aggregate through the calc or removes the calc
2. {{AggregateReduceGroupingRule}}, that reduces unless grouping columns
3. {{PruneAggregateCallRule}}, that removes unreferenced AggregateCall from
Aggregate
4. {{FlinkAggregateRemoveRule}}, that is copied from Calcite's
AggregateRemoveRule, and supports SUM, MIN, MAX, AUXILIARY_GROUP functions in
non-empty group aggregate
5. {{FlinkAggregateJoinTransposeRule}}, that is copied from Calcite's
AggregateJoinTransposeRule, and supports Left/Right outer join and aggregate
with AUXILIARY_GROUP
