Examples of services provided are the transmission of text. When the text is sent to the frontend node, it delegates the backend node, backend performs the transformation task, and returns the result to the original client. The new backend nodes and Frontend nodes can be dynamically

The victory and defeat of the military are not in the future, and the shame of the bag is the male-douniu fighting, fighting, fighting... It has been some time since I learned and used scala. At first, I learned scala mainly to learn the spark

Blog Address: http://blog.csdn.net/yueqian_zhu/ First, actor start Actor starts automatically asynchronously after it is created. When you create Actor, it automatically invokes the Prestart callback method of the Actor trait. This is a very good

Props is a configuration class to specify options for the creation of actors, think of it as an immutable and thus Freely shareable recipe for creating an actor including associated deployment information (e.g. which dispatcher To use, see more

What is actor, an object that encapsulates state and behavior, each actor communicates through a message and reads messages from its own mailbox from another actor. Actorsystem is an entry point into the actor world. Actorsystem is present

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 a
