I. Summary Dispatchers is the heart of the Akka application and this is what makes itHumming. Routers on the other hand, route incoming messages to outbound actors II, Dispatcher type DispatcherFeatures are as follows: Every actor is backed by its own mailboxthe dispatcher can is shared with any number of actorsthe dispatcher can be backed by either thread pool or fork join poolthe dispatcher is optimized for non-blocking code Pinned DispatcherCharac

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

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 throughout the creation and cessation of actors. And it also exists when the entire actor environment is turned off. Props is a configuration class that specifies the creation of an actor. Props props1 = new Props (class name. Class); The
