ulysses you created SPARK-34030:
-----------------------------------

             Summary: Fold RepartitionExpression num partition should at Optimizer
                 Key: SPARK-34030
                 URL: https://issues.apache.org/jira/browse/SPARK-34030
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: ulysses you


We meet some ploblem when backport SPARK-33806. It is because the UnresolvedFunction.foldable will throw a exception. It's ok with master branch, but it's better to do it at Optimizer. Some reason:
 # It's not always safe to call Expression.foldable before analysis.
 # fold num partition to 1 more like a optimize behavior.
