Hi Alexey, I would argue that it's not a problem from Flink's source code, the problem was that Scala introduced a binary incompatible change in Scala 2.12.8. If Flink wanted to allow an upgrade, it would mean breaking snapshot compatibility. That's why Flink is still bound to be used with Scala 2

Hi Günter, David, Let me reply to you both in one email. First of all, thank you for engaging. Günter: - I fully agree that losing Scala API as officially supported in Flink would be very unfortunate. Future of Scala is interesting and will bring more benefits to Flink users. Just to remind ever

Hi Alexey, > Taking into account my Scala experience for the last 8 years, I predict these wrappers will eventually be abandoned, unless such a Scala library is a part of some bigger community like ASF. For the past couple of years, there have been no maintainers for Scala in the Flink community.
