The Axon framework is a CQRS framework created by Allard Buijze. From the beginning I am trying to help him out, mostly by creating samples. This blog post is about a sample I am creating for Google App Engine. Everybody that has been working with Google App Engine (GAE) knows that it enforces some limitations […]
Axon Framework greatly simplifies building CQRS based Event Driven architectures in Java. Such an architecture provides very powerful options in terms of application scalability and extensibility. In this tutorial, I want to go though the process of setting up a basic application architecture with the Axon Framework.
Today, I released version 0.6 of the Axon Framework. 0.6 has many new features and is another step towards full production readiness. There is still some work to do, but first, let’s take a look at what has changed…
Today, I finalized the 0.5 release of the Axon Framework. There is quite a number of changes since the 0.4 version. The 0.5 version is a major step towards production readiness of the framework. Besides some changes to existing building blocks, such as the event bus, which is now much more powerful, the 0.5 version […]
Last week, I published the 0.4 release of the Axon Framework. Axon helps developers build high performance, scalable and extensible applications using the CQRS pattern. The 0.4 release is a major step towards 1.0, and includes transactional event handling, high-performance caching repositories and easy configuration of event sourcing support. Furthermore, we have also built a […]
Command-Query Responsibility Segregation (CQRS) is slowly but steadily gaining ground as an architecture that helps developers to develop scalable, extensible and maintainable applications. Events play a major role in this architecture, and the way you design these events greatly influence the extensibility of your application. In this post, I describe some CQRS event basics and […]
