When using AxonFramework together with PostgreSQL, you will find out that PostgreSQL uses something that is called TOAST (The Oversized Attribute Storage Technique).

It means that PostgreSQL uses a fixed page size of 8 KB and does not allow for tuples to use multiple pages; Postgres will compress the data. You can find more info about TOAST in the PostgreSQL wiki.

Sometimes the most challenging part of any project is getting started. Tasks such as creating the structure for various project artefacts, creating a build file, determining maven coordinates, and picking the right dependency versions can be boring and repetitive. But tragically, Axon Framework isn’t available in the Spring Initializr. So, at AxonIQ, we felt it was high time that we corrected this glaring oversight by providing our very own AxonIQ Initializr just for you, our loyal Axonians!

In my previous blog, I spent just a little bit of text on the challenges of using a single StatefulSet scaled to the number of nodes we want in the cluster. Also, I completely skipped the subject of using Helm to manage the deployment. Both subjects do merit more attention, so let’s do just that.

CQRS/ES are patterns and to be more specific they are Application Design patterns and their implementation spans across 3 main Architectural areas: structural and continuity, operational and extensibility, and cross-cutting and usability. To help pinpoint the exact implementation areas, let us look at two terms commonly used in Enterprise Architecture - Capabilities and Capability Maps.

In message-driven systems, messages flow in a lot of directions.The right to data erasure is a requirement that is common in security laws. At first glance, the right to erasure seems to be contradictory to event sourcing. A solution to overcome this problem is crypto shredding. AxonIQ’s Data Protection Module takes a declarative approach to encrypting sensitive data.

Requests like “How do I ensure the email address in a User aggregate is unique?” reach us quite often. We can rephrase them: How do I consistently validate consistency among a set in such a system? These are issues encountered when using CQRS in combination with Event Sourcing. Due to this, they crop up when using Axon Framework. Before diving into how to tackle this with Axon, let us first explain the problem we face here.

Well, the "old me" would design an application "on the fly;" AKA, create a repository on GitHub, open it on IntelliJ, and BAM! You’ve got an application. Success?
