Go Reactive with Java 8

We are very excited about the release of Java 8!  The new Lambda syntax makes it much easier for Java developers to go Reactive. The foundation of Reactive is Event-Driven. To be Event Driven you need an easy way to create and spawn up small independent tasks in an asynchronous fashion. Lambdas gives us exactly this, avoiding the usual anonymous inner classes that make code hard to comprehend. Combining Lambdas with Akka and Play Framework create a concise and cohesive programming model for Reactive applications on the JVM.

Staying in Contact with an Actor’s Acquaintances

@rolandkuhn
October 8, 2013
Akka

When an actor confers with another to use its services—most likely on a remote actor system—you will always have to handle the case that the other actor goes away. Either it terminates or the node crashes or the network connection fails, sooner or later something will go wrong. Instead of making dedicated network monitoring available, Akka follows a more general approach, focusing on the service you need instead of on the implementation details.

Announcing Akka 2.1.1

@akkateam
February 26, 2013
Akka

We are pleased to announce the first maintenance release of the 2.1.x series of the Akka toolkit, fixing several issues including the following:

  • A possible thread leak at system shutdown
  • A bug in the scheduler which would delay tasks too long if scheduled a multiple of the wheel duration (defaults to 51.2 seconds) into the future
  • Wrong error handling when sending non-serializable or too large remote messages, leading to silent loss and extraneous reconnect

This update is backwards binary compatible, meaning that the JAR files of release 2.1.1 are a drop-in replacement for 2.1.0—but not the other way around. We recommend that all users upgrade at their earliest convenience. Please refer to the full announcement for more details.

Happy hAkking!

We are pleased to announce the availability of Akka 2.1.0 ‘Mingus.’ This is the next step of Akka’s evolution, following the major transformation that was 2.0—you are invited to look back at the announcement from March 6, 2012. The 2.0 release laid the groundwork, with a completely message-based internal structure that enables your actor-based services to interact regardless of where they are hosted. As a result, you can scale up and out by configuration at deployment time. Today’s release adds cluster support, forming a powerful substrate on which elastic cloud-based applications are built.

  • Stop using Unsafe.throwException to allow running on Android
  • Configurable worker pool size in remoting to allow running with fewer threads

We strongly recommend updating all projects using the 2.0 series to this version. Please see the full announcement for more details.
