> URL: https://issues.apache.org/jira/browse/FLINK-20791
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API, Table SQL / Planner
> Reporter: Sebastian Liu
> Assignee: Sebastian Liu
> Priority: Major
> Labels: stale-assigned
>
> Aggregate operator of Flink SQL is currently fully done at Flink layer. With
> the developing of storage, many downstream storage of Flink SQL has the
> ability to deal with Aggregation operator.
> Pushing down Aggregate to data source layer will improve performance from the
> perspective of the network IO and computation overhead.
>
> I have drafted a design doc for this new feature.
