Often people ask: what is the difference between Akka's actor and Scala's actor? The answer here is that, from the Actor model point of view, there is no difference, they all implement the actor model.Akka actors and Scala actors are both implementations of that model.All actors model says that your concurrency primiti

Akka-Build a toolset for highly concurrent, distributed, and fast-recovering message-driven applications on the JVMWe believe that it is too difficult to write the correct concurrency program with fault tolerance and scalability. This is mostly because we use the wrong tool and the wrong level of abstraction. Akka was born to change the situation. By using the Actor model we raise the level of abstraction and provide a better platform (tool) for build

First part: Actor Architecture Akka version 2.5.8Copyright NOTICE: This article for Bo Master original article, without Bo Master permission not reproduced. Akka provides you with some basic functionality for creating an actor system, and has implemented the underlying code necessary to control basic behavior. To understand this, let's take a look at the relationship between the

Actor model and Akka I. Actor model Actor Model ConceptA conceptual model for dealing with concurrency computation the state of an actor is maintained by its own behavior, and external threads cannot invoke the behavior of the object directly, and must pass the message to excite the behavior, thus guaranteeing that t

Actor model is a kind of message passing model based on coprocessor, which has good performance in parallel computation and concurrent message transmission. The Generic Actor Module Framework provides ultra lightweight threads and tools for fast, secure, 0-replicated messaging between these threads. In languages such as Elang,ruby,lua, the VM supports the process directly at the VM level, and VMS help you s

Even with the introduction of concurrency updates in Java 6 and Java 7, the Java language still does not make parallel programming particularly easy. Java threads, synchronized code blocks, wait/notify, and java.util.concurrent packages all have their own locations, but Java developers are relying on technology pioneered in other languages in the face of capacity pressures on multi-core systems. The actor model is a technology that has been implemente

In the previous article, we briefly introduced the actor system, indicating that there is a hierarchical relationship between actor, which is also the most basic unit for actor applications. This article introduces some basic concepts of actor.An actor contains state, behavior, mailbox, and supervisor strategy (Adminis

Before describing how to create an actor, let's look at a class props. Props is a configuration class that specifies the parameters for creating actors, and so on. The following are some typical applications of Props, Props1) directly into the class of the actor you need to create Import Akka.actor.ActorRef; Import Akka.actor.ActorSystem; Import Akka.actor.Props; Import Akka.actor.UntypedActor; public cla
