>                 Key: SPARK-49184
>                 URL: https://issues.apache.org/jira/browse/SPARK-49184
>             Project: Spark
>          Issue Type: Umbrella
>          Components: Connect, PS, PySpark
>    Affects Versions: 4.0.0
>            Reporter: Ruifeng Zheng
>            Assignee: Ruifeng Zheng
>            Priority: Major
>
> 1, Some plots depends on MLlib and don't work with Spark Conenct. We need to reimplement ML-based plots with Spark SQL, so they can be compatible with Spark Connect;
> 2, Further computation optimization, e.g.:
>  * compute all necessary metrics for some plots in single pass of the whole dataset, so we can improve the performance;
>  * optimize existing sampling algorithm
