[jira] [Created] (SPARK-41198) Streaming query metrics is broken with CTE

Jungtaek Lim created SPARK-41198:
------------------------------------

             Summary: Streaming query metrics is broken with CTE
                 Key: SPARK-41198
                 URL: https://issues.apache.org/jira/browse/SPARK-41198
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 3.3.1, 3.2.2, 3.4.0
            Reporter: Jungtaek Lim


We have observed a case the metrics are not available for the streaming query which contains CTE.

Looks like CTE was inlined in analysis phase in Spark 3.1.x and it was changed to be inlined in optimization phase in Spark 3.2.x. ProgressReporter depends on analyzed plan, hence the change made ProgressReporter to see CTE nodes, which ends up with having different number of leaf nodes between analyzed plan and executed plan.
