Jazoon 2012: Akka 2.0 – Scaling up and out with Actors

Concurrency is too hard but we need it. In his talk “Akka 2.0 – Scaling up and out with Actors,” Viktor Johan Klang showed new features of Akka 2.0.

The framework now uses Future to create pipes between actors and Promise to write data to, say, a stream (docs).

To make error handling more simple, there is now “parental supervision.”

Decoupling actors becomes even more with the Event Bus API.

There is support for ZeroMQ to create grids/meshes of actors (docs).

But every framework has its limitations. If you hit one of those, it’s usually either “Use the Source, Luke” or “You’re out of luck”. Akka 2.0 comes with a new extensions mechanism to hook into the framework.
