Threads are still a complex topic to get right in Java due do -racing conditions -dead locks -shared state. In the post following this one, I show how to enhance the example code in order to be able to process a very high number of messages : Akka actors : 10 millions messages processed (1s / message) in 75 seconds ! There's a perfectly good example of a simple chat room server using the Play Framework, WebSockets, and Actors. Recently we added AMQP support to lift by wrapping RabbitMQ's client libraries with Scala Actors. WebSockets Echo Using Play, Scala, and Actors, Part I. The way my system is architected, whenever we change the list of keywords, a ShowDataErased message is sent, followed by a bunch of ShowKeywordsReplaced events, one per show. Scala Actors help us use those ideas in lift. Akka actors unit testing with Scala I'm fairly new to Scala so please be gentle. One of the key performance attributes for Actors is the speed with which messages can be consumed and processed. The good part is that once I had my misconceptions cleared out, it was much easier to understand some weird parts of the Scala standard actors, and the path to understanding the design of Akka became much clearer. From Updating Filter Predicates. It is a major rewrite, using Akka actors at the core and Spray for the REST layer. In the app I'm building, I'm using Akka actors and I want to write some unit tests. But I promised to talk about scala.util.DynamicVariable in the blog post's title, didn't I? Scala 2.8 Remote Actors in Scala 2.7.7-final. According to my googling experience on the issue, this is the first time someone met the problem and solved it. Let's say (initially) I want to migrate all my service calls to scala actors. ElasticMQ 0.7.0, a message queueing system with an actor-based Scala and Amazon SQS-compatible interfaces, was just released. The Scala programming language provides an Actor based framework for handling concurrency. After a lot of heavy use of the remote actors libraries in Scala, I noticed that something seemed to be leaking memory. Scala's Actor model for concurrent programming was originally inspired by the Erlang programming language.
