> Add tree pattern pruning to CTESubstitution rule
> ------------------------------------------------
>
> Key: SPARK-37379
> URL: https://issues.apache.org/jira/browse/SPARK-37379
> Project: Spark
> Issue Type: Sub-task
> Components: Optimizer
> Affects Versions: 3.1.0
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Priority: Major
>
> I propose to add tree pattern pruning to the CTESubstitution rule in order to
> skip tree traversal when the tree does not contain an UnresolvedWith
> expression.
> This is motivated by profiling a job which uses DataFrame APIs to
> incrementally construct a huge query plan (200k+ nodes): each API call
> results in eager re-analysis of the plan, of which CTESubstitution accounts
> for the majority of the analysis time. This query didn't contain CTEs, so
> skipping the CTESubstitution significantly speeds up analysis.
> I plan to submit a patch for this.
