[jira] [Created] (SPARK-35232) Nested column pruning should retain column metadata

Chao Sun created SPARK-35232:
--------------------------------

             Summary: Nested column pruning should retain column metadata
                 Key: SPARK-35232
                 URL: https://issues.apache.org/jira/browse/SPARK-35232
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Chao Sun


It seems we should retain column metadata when pruning nested columns. Otherwise the info will be lost and will affect things such as re-constructing CHAR/VARCHAR type (SPARK-33901).
