Akka Actor: Starting with the simplest example

What is Akka. It provides the Actor programming model on the JVM-both concurrency and distribution. It was written by Scala, instead of the Actor of Scala itself. The Actor's vision is a heavyweight resource, capable of higher concurrency with a small amount of memory, something like a fiber, a process. One data comparison is the same 1GB memory, can create 2.7M actors, and threads can only create 4,096, for reference only, of course, Java will also be based on the thread pool to execute.

The Actor adds flexibility to the program and eases complexity (the standard compliment).

The so-called Action programming model takes into account concurrency and distribution, because it allows you to program without thinking about threads, thread configuration becomes the scope of deployment; Communication between actors can only send asynchronous messages, and actors may be distributed on the same JVM, different JVMs, or different physical machines.

Because the first example from Akka in action is a bit high, a simple example of the Akka actor is found on the web, from the easy Scala Akka actor examples (Hello, World Examp Les). Not purely translation, mainly for practiced hand, so not exactly the same: Read the full text >>
