I've always used Scala in the context of Flink. Now that Flink 1.15 has become Scala-free, I wonder what is the best (most practical) route for me moving forward. These are my options:
1. Keep using Scala 2.12 for the years to come (and upgrade to newer versions when the community has come up with something). How long is Flink expected to support Scala 2.12? 2. Upgrade to Scala 2.13 or Scala 3 and use the Java API directly (without any Scala-specific wrapper/API). How problematic will that be, especially regarding type information & scala-specific serializers? I hate those "returns" (type hints) in the Java API... 3. Switch to Java, at least for the time being... To be clear, I have a strong preference for Scala over Java, but I'm trying to look at the "grand scheme of things" here, and be pragmatic. I guess I'm not alone here, and that many people are indeed evaluating the same pros & cons. Any feedback will be much appreciated. Thanks in advance!
