Akka Typed is back for round 4!

Tour of Akka Typed: Event Sourcing

Manuel Bernhardt continues his series about Akka Typed, the new Akka Actor API that brings significant advantages over the classic one. In his fourth entry, he takes a closer look at one of the most popular use-cases for Akka: event sourcing.

It's time for part 3 of the Akka Typed series

Tour of Akka Typed: supervision and signals

Manuel Bernhardt is back for part three of his series about Akka Typed, the new Akka Actor API that brings significant advantages over the classic one. In his third entry, he looks at one of the core concepts of actor systems: supervision and failure recovery.

Let's build a payment processor with Akka Typed

Tour of Akka Typed: Protocols and Behaviors

Manuel Bernhardt starts a new series about Akka Typed, the new Akka Actor API that brings significant advantages over the classic one. This first entry gets started by easing into the topic to show us a little bit of what it’s capable of. He talks about how to build a payment processor making the most of Akka Typed.

There's never too much of a good thing

Akka anti-patterns: Too many actors

Manuel Bernhardt’s Akka anti-patterns series continues. This time, he takes a closer look at a very frequent anti-pattern that can be found in codebases written by developers who have just discovered the actor model; and that is to have too many actors. Whilst Akka is entirely capable and designed to run many actors, this isn’t always the best approach.

You sure you've been doing it the right way?

Akka anti-patterns: Java serialization

The Akka documentation discourages the use of Java serialization but performance is just one reason to not use Java serialization – there are stronger reasons to not engage with it, especially in the context of Akka. What to do instead? In this article, Manuel Bernhardt gives some alternatives.

Useful or not?

Akka anti-patterns: Stateless actors

What is the importance of actors and why stateless actors make little sense? In this article, Manuel Bernhardt briefly explains the main purpose of actors and their state.

Trivial pursuit

How well do you know your Akka trivia?

It’s time for another programming pub quiz! This week, we’re testing your knowledge about Akka. Do you know everything there is to know about this toolkit for building concurrent applications on the JVM?

How-to

A tour of Akka cluster – Cluster sharding

The tour of Akka cluster continues! In the previous article, we learned how to use techniques for making a reactive payment processor resilient to failure using Akka Cluster. Here, Manuel Bernhardt takes a closer look at how to scale out the reactive payment processor application using cluster sharding.

Let's go exploring!

A tour of Akka Cluster – Akka distributed data

How can we make building distributed systems easier? In this article, Manuel Bernhardt explores one useful tool in the Akka toolbox: Akka Cluster. Today, we’re taking a closer look at one module, Akka Distributed Data, and how it can be used to build an example reactive payment processor.
