> 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.
