Hi Josh, Currently Flink supports Java, Scala and Python for defining SQL UDFs. There are no concrete plans to extend the set of supported languages at the moment.
In general, these kinds of contributions are always welcome. What we have to make sure is to see how it fits into the overall story. In order to assess this, I would recommend writing to d...@flink.apache.org to propose your idea and the solution proposal.
