What is the difference between Typed and UnTyped Actors in Akka? When to use what?

Question

I have tried to read the Akka documentation to find out the exact difference between Typed and Untyped actors. When to use what? I am not sure what I\'m missing. Can somebody po

Answer 1

Akka untyped actors "do not compose" and "are not usefully typed".

This defeats the very reason we use Scala: it's functional programming power. See http://noelwelsh.com/programming/2013/03/04/why-i-dont-like-akka-actors/ for in depth on this mindset.

Also, see attempts to improve this in Scala to match the Haskell way.

Seems to still be experimental in Akka or even dropped - not clear.

This idea of typed channels makes a lot of sense because similar issues occur when one tries to build type checked data (analytics) pipelines.

Akka Typed seems to be a great evolution to a safer programming model: https://opencredo.com/akka-typed/
