Re: Flink Not sure if you've seen this, we basically write scala which call into Flink's Java api, and library this flink-adt help smooth out the process. I think Flink will eventually drop scala api, which is a good thing since calling Java from Scala is trivial, and less burden for maintainers. https://github.com/findify/flink-adt
For anything meta-programming, I've heard good things about the Myriad library: https://github.com/MoiraeSoftware/myriad
