Akka 3 Akka actor 与

经常有人问: Akka的Actor和Scala的Actor有什么不同？这里的回答是，从actor 模型角度讲，没什么不同，它们都实现了actor model.

Akka actors and Scala actors are two implementations of that model.

All Actor model says that your concurrency primitives are actors, which can:

• receive a message and decide what to do next depending on the content of the message, including:
• send messages to any actors they know about
• create new actors

and provides certain guarantees, e.g.:

• any actor will only handle a single message at a time
• messages sent by actor X to actor Y will arrive in the order thay were sent

There is no difference between Scala and Akka actors on this level.

具体实现的不同请参考附件

我个人学习Akka的Actor的原因是Spark使用Akka作为消息驱动系统
