[jira] [Created] (SPARK-41732) Session window: analysis rule "SessionWindowing" does not apply tree-pattern based pruning

Jungtaek Lim created SPARK-41732:
------------------------------------

             Summary: Session window: analysis rule "SessionWindowing" does not apply tree-pattern based pruning
                 Key: SPARK-41732
                 URL: https://issues.apache.org/jira/browse/SPARK-41732
             Project: Spark
          Issue Type: Bug
          Components: SQL, Structured Streaming
    Affects Versions: 3.3.1, 3.2.2, 3.4.0
            Reporter: Jungtaek Lim


We missed to apply tree-pattern based pruning in the rule SessionWindowing, which leads to evaluate SessionWindowing unnecessarily to the other logical nodes multiple times.
