It’s been a while since I reviewed options for the actor model in Python, but when I started an ongoing personal project a couple years ago, I ended up deciding to use Akka and Scala instead (in part because the pattern matching is so rich, and I think in part due to GIL issues). In particular I’m using Akka 2.6’s typed Behaviors DSL, which allows for more functional-style programming.I haven’t looked at Pykka in a while (or Pekko) but I think Akka can be a good reference point.
(I just recently started with the idea of voting with my actors, thanks to this recent comment.)
