------------------------------------

             Summary: Add option for partial nested field writes with nullable fields.
                 Key: SPARK-38408
                 URL: https://issues.apache.org/jira/browse/SPARK-38408
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.3.0
            Reporter: Holden Karau


If a nested field has nullable entries a user shouldn't have to specify all of the fields, instead the nullable fields can have the default value of null. This will allow for more effective schema migration. We might want to put this behind a feature flag though.
