We have two great talks lined up for this event.

Scala 3, what does it means for me? By Joan Goyeau

Weve all heard about Dotty or Scala 3 either through Martin Oderskys great talks or features listing on Dottys website. This sounds like a big change but how will it affect me as a Scala user in my day to day development?

Here at Netflix we are processing millions of events per second with Scala, so weve hit a few corner cases of the language that often end up in complicated & boilerplate workarounds that new features in Scala 3 are believed to be solving.

Please join this talk to see what the future of the Scala landscape looks like for you & discuss your own compilation stories.
