Apache Spark reassigned SPARK-40773:
------------------------------------
Assignee: (was: Apache Spark)
> Refactor checkCorrelationsInSubquery
> ------------------------------------
>
> Key: SPARK-40773
> URL: https://issues.apache.org/jira/browse/SPARK-40773
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Allison Wang
> Priority: Major
>
> Currently, the logic in `checkCorrelationsInSubquery` is inefficient and
> difficult to understand. It uses `foreachUp` to traverse the subquery plan
> tree, and traverses down an entire subtree of a plan node to check whether it
> contains any outer references. We can use recursion instead to traverse the
> plan tree only once.
