> ------------------------------------------------------------------------
>
> Key: SPARK-36559
> URL: https://issues.apache.org/jira/browse/SPARK-36559
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, SQL
> Affects Versions: 3.2.0
> Reporter: Hyukjin Kwon
> Priority: Major
>
> https://issues.apache.org/jira/browse/SPARK-36338 implemented distributed sequence implementation on JVM side. However, it disables leveraging Spark SQL engine because it creates an RDD directly, and truncate the SQL plans.
> We should move the logic into a proper SQL plan to leverage other optimizations such as column pruning.
