besides Ray, are there other tools or platforms that embrace the agent actor architecture model?

https://www.erlang.org/ https://elixir-lang.org/

Elixir is amazing, see also stuff like https://github.com/bitwalker/libcluster . I'm always surprised there's not more excitement generated by the possibility of having language-level features that would normally require all the weight of something like k8s. I don't get the impression that many people are seriously using it for data-engineering work though, which seems like a shame

Elixir definitely!

If you need to use Go, there is also ergo: https://github.com/ergo-services/ergo

Yet another cool tool is lunatic: https://github.com/lunatic-solutions/lunatic

Estuary Flow derivations [1], I suspect (I work here)? You write a program which has messages pushed to it, which maintains and updates an internal state, and which publishes output messages.

You can build cyclic data-flows [2] - not just DAGs - which seems a key ingredient.

You can also write contract-based tests that verify the end-to-end behaviors of your "agents" [3].

Today, you're limited to SQLite or TypeScript. Looking forward, we aim to open it up to any program packaged in a docker container.

Akka uses the actor model. https://doc.akka.io/docs/akka/current/typed/actors.html

IIRC, Akka based their implementation on Erlang (possibly OTP), but it's been a long time since I did anything with either Erlang or Scala, and I never used Akka in Java.

Akka was indeed inspired by Erlang. For a modern take, there's Apache Pekko (incubating), a fork of Akka 2.6.x https://github.com/apache/incubator-pekko

Dask added an actor model after seeing it in Ray. I’ve used dasks in some computationally intensive applications (already had existing dask infrastructure which is why we didn’t go with rays)
