Joris Kuipers CTO of Trifork in Amsterdam will present:
Day 2 problems in CQRS and Event Sourcing
You’ve seen the talks, read the blogs and even built the proof-of-concept, and now you know: your next system will be using CQRS and event-sourcing! And you’re probably right: these patterns provide several unique advantages, and when you’re using Axon you’ll be benefiting from years of experience from the people pioneering this approach on the JVM.
Unfortunately, no framework can shield you from having to deal with the “Day 2 problems” that will arise once your system is running in production and you’re busy evolving it. In this talk, Joris will address some of these issues, such as deploying updates (need for custom migration tools, problems with blue-green deploys and rolling back updates), evolving aggregates with many events, sharing events that used to be private between services when breaking up your applications, and other things you don’t typically hear about from the enthusiasts who only just started to work with this approach. But fear not: apart from raising issues, Joris will share approaches to deal with them as well, leaving you prepared to evolve your application so it can live happily ever after in production!
