Introduction to Akka Actors with Java 8

One of the really good abstractions Akka brings to the table is Actors, which allows you to write concurrent code but without much of the pain doing so compared to writing your code using threads and locks.

In this webinar we take a look at the basics of writing actors with Akka in Java 8, what actors and the core concepts around them are, how you write one, what to do and what not to do when using Akka.

Interesting, great job. Can a session like this be created for Akka Persistence or is there one existing already?

[mazenezzeddine]

Thanks.

Does the fact that messages can be received out of order make the system undeterministic? any implications?



Messages should be immutable, does that place any constraint on the use-cases? can the actor model express any concurrent or distributed application use case?

Bad code style. Akka is very exotic framework. Learn it, just lost your time.
