[jira] [Created] (SPARK-33007) Optimize to_json + named_struct + from_json expression chain

L. C. Hsieh created SPARK-33007:
-----------------------------------

             Summary: Optimize to_json + named_struct + from_json expression chain
                 Key: SPARK-33007
                 URL: https://issues.apache.org/jira/browse/SPARK-33007
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: L. C. Hsieh
            Assignee: L. C. Hsieh


Due to query optimization, it is possibly to generate inefficient json expression chain like to_json(named_struct(col1, from_json(json).col1, col2, from_json(json).col2), ....). We could optimize it.
