We, as experienced users and consultants for Axon, encourage developers that work with Axon Framework or are considering working with it, to read the following blog by Frans van Buul from AxonIQ. This blog explains in a clear and structured way, how to avoid the pitfalls that can happen when replaying past events after changing/adding read models. […]
Machine Learning creates lots of value in the business processes, if and when applied properly and the right data is available. These days a lot of data is already held within organisations. It is common to see this data unused, with possibilities and insights unseen. While it can be due to limitations of modelling and […]
On my current project, we opted not to use REST for the communication between our services. Instead we make use of AxonIQ’s AxonHub, which acts as a specialized message broker. Messages can be of three types: Command – You want to change something Event – You want to inform others of something that happened Query […]
The client I work for at this time is leveraging Axon 3. The events are stored in a PostgreSQL database. PostgreSQL uses a thing called TOAST (The Oversized-Attribute Storage Technique) to store large values. From the PostgreSQL documentation: “PostgreSQL uses a fixed page size (commonly 8 kB), and does not allow tuples to span multiple […]
Imagine you’re using Axon to run an event sourcing application. Your production event store might contain millions of events, created in various versions of the application. Wouldn’t it be nice to know for sure that the latest version of your application plays nicely with all your production events and Sagas, including those from previous versions? […]
Fresh from university, searching for a development job, having one within two weeks. And at an interesting company at that. That is what happened to me about a year ago.

Recently, Axon Framework 2.1 has been released. It comes packed with improvements and some exciting new features. In this post, I’ll briefly iterate of what’s new in this version. Furthermore, we have also scheduled a few workshops and trainings.
The Axon release Party, which was organized on Thursday last week, has been a great success. The event was at the Observant in Amersfoort and with 40 curious enthusiastic attendees we kicked the day off with a nice lunch. Following that, Allard gave an introduction on CQRS and presented the latest features of Axon 2. E.Novation and Aktive Reply presented their case studies, showing how they used Axon in their applications. Finally, an panel of experts was interrogated during the Panel Discussions. A nice cold drink and some snacks gave the final touch to the day.
