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

             Summary: Retain empty protobuf message in schema for rpotobuf connector
                 Key: SPARK-46736
                 URL: https://issues.apache.org/jira/browse/SPARK-46736
             Project: Spark
          Issue Type: Improvement
          Components: Protobuf
    Affects Versions: 4.0.0
            Reporter: Chaoqin Li


Since Spark doesn't allow empty StructType, empty proto message type as field will be dropped by default. Introduce an option to allow retaining an empty message field by inserting a dummy column.
