Hi @Jose Gonzalez​ and thank you for the reply! That library seems out of date and lacks documentation. I wonder if ScalaPB would be a better option. I don't have any scala experience, but since scala UDF's perform well with Spark. I suppose learning Scala and taking this approach would be an option. There would be some other benefits too (such as writing other Databricks UDF's in Scala for performance increasement)

It is starting to seem that the best option for MVP is actually the Python-based option that is used as a wheel library in Databricks.
