[jira] [Created] (SPARK-42918) Introduce abstractions to create constant and generated metadata fields

Johan Lasperas created SPARK-42918:
--------------------------------------

             Summary: Introduce abstractions to create constant and generated metadata fields
                 Key: SPARK-42918
                 URL: https://issues.apache.org/jira/browse/SPARK-42918
             Project: Spark
          Issue Type: Improvement
          Components: Optimizer
    Affects Versions: 3.4.1
            Reporter: Johan Lasperas


As a follow-up on https://issues.apache.org/jira/browse/SPARK-41791 that introduced `FileSourceConstantMetadataAttribute` and `FileSourceGeneratedMetadataStructField` to handle constant and generated metadata columns, we may want to introduce corresponding abstractions for struct fields to allow creating metadata fields more easily.
