No one knows for sure except Apache, but I’d learn Scala 2 if I were you. Even if Spark one day migrates to Scala 3 (which is not given), it’ll take a while for the industry to adjust. It even takes a while to move from Spark 2 to Spark 3 (Scala 2.11 to Scala 2.12). I don’t think your knowledge of Scala 2 will be outdated any time soon. You can also compare it with Python 2 vs 3: although Python 3 dominates these days (almost 15 years after the release!), Python 2 is still used. >Понедельник, 10 октября 2022, 10:24 +03:00 от Oliver Plohmann < >oli...@objectscape.org >: > >Hello, > >I was lucky and will be joining a project where Spark is being used in >conjunction with Python.
