----------------------------------

             Summary: QueryExecutionListener does not see any observed metrics 
fired before persist/cache
                 Key: SPARK-35695
                 URL: https://issues.apache.org/jira/browse/SPARK-35695
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Tanel Kiis


This example properly fires the event
{code}
spark.range(100)
  .observe(
    name = "other_event",
    avg($"id").cast("int").as("avg_val"))
  .collect()
{code}

But when I add persist, then no event is fired:
{code}
spark.range(100)
  .observe(
    name = "other_event",
    avg($"id").cast("int").as("avg_val"))
  .persist()
  .collect()
{code}
