[GitHub] [spark] jchen5 commented on pull request #43061: [SQL] Throw an error for correlated exists/IN subqueries with LIMIT clauses

jchen5 commented on PR #43061:
URL: https://github.com/apache/spark/pull/43061#issuecomment-1733888223

   Note that after these two PRs, the state is as follows:
   - Newly enabled: Correlated scalar/lateral subqueries with LIMIT, which required new logic in DecorrelateInnerQuery
   - Newly enabled: Uncorrelated IN/EXISTS subqueries with LIMIT, which did not require any new logic other than allowing them through CheckAnalysis.
   - Still disabled: Correlated IN/EXISTS subqueries with LIMIT.
