Reynold Xin updated SPARK-7320:
-------------------------------
Summary: Add rollup and cube support to DataFrame Java/Scala DSL (was: Add rollup and cube support to DataFrame DSL)
> Add rollup and cube support to DataFrame Java/Scala DSL
> -------------------------------------------------------
>
> Key: SPARK-7320
> URL: https://issues.apache.org/jira/browse/SPARK-7320
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Reynold Xin
> Assignee: Cheng Hao
> Labels: starter
> Fix For: 1.4.0
>
>
> We should add two functions to GroupedData in order to support rollup and cube for the DataFrame DSL.
> {code}
> def rollup(): GroupedData
> def cube(): GroupedData
> {code}
> These two should return new GroupedData with the appropriate state set so when we run an Aggregate, we translate the underlying logical operator into Rollup or Cube.
