> ------------------------------------------------------------------
>
> Key: SPARK-37036
> URL: https://issues.apache.org/jira/browse/SPARK-37036
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 3.2.0
> Reporter: Haejoon Lee
> Priority: Major
>
> Pandas API on Spark has some features that potentially cause the performance degradation or an unexpected behavior e.g. `sort_index`, `index_col`, `to_pandas`, etc.
>
> We should raise the proper advice warning for those functions so that users can adjust their pandas-on-Spark code base more robust.
