   >  unsigned numeric to decimal @alamb do we need to support this? My opinion is that unsigned data type is not in the standard SQL data type, and we no need to support this.
   
   
   @liukun4515  I personally think it would be valuable to support `unsigned` numeric (aka `PrimitiveArray<T>`) to / from the decimal type. Arrow is used for more than just SQL engines. However, I think it is fine to leave it as a follow on PR / issue (doesn't have to be in the first implementation).
   
   I suspect once you implement `PrimitiveArray<T>` to/from `DecimalArray` for signed variants the incremental cost to supporting the unsigned numeric variants will be quite low.
