Axon Framework 5.0.0-preview Feedback

Axon Framework AF5 Milestones
1

Hello!

Over the past week, I’ve had the opportunity to build a basic CRUD application using Axon Framework 5.0.0-preview, after doing just so with Axon Framework 4 a little while earlier.

Most of my application is based on the provided guide which helped massively with getting things going initially.

The DCB is an amazing upgrade and I am personally very interested in seeing how well this concept performs in highly concurrent settings, especially in contrast to the Aggregate we had before.

My biggest struggles were understanding the required Configurations as well as configuring my Projector correctly, but seeing as I started out on Milestone 3 and switched halfway through the project development to 5.0.0-preview I think a lot of my confusion was down to the changes between versions. Nevertheless, I would greatly appreciate having some more examples for this.
