> -------------------------------------------------
>
> Key: SPARK-39825
> URL: https://issues.apache.org/jira/browse/SPARK-39825
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: XiDuo You
> Priority: Major
>
> Push LeftSemi/LeftAnti through project is not always effective
> 1. project is used to do column pruning, so it conflicts with ColumnPruning
> 2. if the project contains complex expression and join condition reference
> it, it can be regression since the complex expression will be evaluated more
> than once
