> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Legacy Planner
> Reporter: Chengxiang Li
> Assignee: Chengxiang Li
> Priority: Major
>
> The scope of this sub task includes:
> # Partial aggregate interface.
> # Simple aggregate function implementation, such as SUM/AVG/COUNT/MIN/MAX.
> # DataSetAggregateRule which translate logical calcite aggregate node to
> Flink user functions. As hash-based combiner is not available yet(see PR
> #1517), we would use sort-based combine as default.
