there is a set of DataFrame APIs implemented in [`StatFunctions`](https://github.com/apache/spark/blob/9cae423075145d3dd81d53f4b82d4f2af6fe7c15/sql/core/src/main/scala/org/apache/spark/sql/execution/stat/StatFunctions.scala) and [`DataFrameStatFunctions`](https://github.com/apache/spark/blob/b69c26833c99337bb17922f21dd72ee3a12e0c0a/sql/core/src/main/scala/org/apache/spark/sql/DataFrameStatFunctions.scala), which I think can not be implemented in connect client due to: 1. depend on Catalyst's analysis; 2. implemented in RDD operations; 3. internally trigger jobs (like `summary`); this PR is to find a way to support arbitary `DataFrame => DataFrame` method -- This is an automated message from the Apache Git Service.
