> ------------------------------------------------------------
>
> Key: SPARK-13798
> URL: https://issues.apache.org/jira/browse/SPARK-13798
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> If the Aggregate does not have any aggregate expression, it is useless. We can replace Aggregate by Project.
> Then, Project can be collapsed or pushed down further.
> This only makes sense when the grouping and aggregate are identical. Thus, will do it later
