URL: https://github.com/apache/arrow-datafusion/issues/5358

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Currently, the protobuf serialisation does not support Arrow Map types.  This means that any query from `ballista` on, say, a Parquet file that contains Map data structures will fail to serialise the Arrow Schema, and hence lead to failure of the whole query (regardless of whether the query actually touches the Maps in the Parquet).
   
   **Describe the solution you'd like**
   Add the missing functionality to serialise Arrow Map data types to `datafusion/proto/proto/datafusion.proto` and the related serialisers.
   
   **Describe alternatives you've considered**
   I could not see any alternatives.
   
   **Additional context**
   None
