[jira] [Created] (SPARK-33817) Use a logical plan to cache instead of dataframe

Terry Kim created SPARK-33817:
---------------------------------

             Summary: Use a logical plan to cache instead of dataframe
                 Key: SPARK-33817
                 URL: https://issues.apache.org/jira/browse/SPARK-33817
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Terry Kim


When caching a query, we can use a logical plan instead of a dataframe (current implementation) to avoid creating the dataframe.

This is also consistent with uncaching which uses a logical plan.
