So, I'm currently working on a project in which I've decided to employ the CQRS/ES architectural combo. Given the system is event sourced, I required read models built from the domain events and, conveniently, had blogged about doing this as one of my first posts on this blog.
It was very satisfying to be able to refer back to that blog post to re-familiarize with the pattern and I must say that so far everything is working beautifully. Stay tuned for a future post on using RX to implement a CQRS/ES application in a reactive manner.
