[jira] [Created] (SPARK-32430) Allow plugins to inject rules into AQE query stage preparation

Thomas Graves created SPARK-32430:
-------------------------------------

             Summary: Allow plugins to inject rules into AQE query stage preparation
                 Key: SPARK-32430
                 URL: https://issues.apache.org/jira/browse/SPARK-32430
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Thomas Graves


Provide a generic mechanism for plugins to inject rules into the AQE "query prep" stage that happens before query stage creation.

this goes along with https://issues.apache.org/jira/browse/SPARK-32332 where the current AQE implementation doesn't allow for users to properly extend it for columnar processing. 

The issue here is that we create new query stages but we do not have access to the parent plan of the new query stage so certain things can not be determined because you have to know what the parent did.  With this change it would allow you to add TAGs to be able to figure out what is going on.
