CQRS & EventSourcing in the Wild

The fact that this didn't present event sourcing or CQRS as the shining silver bullet was a refreshing change. It validated a lot of idea's while giving a nice perspective of things to come in my journey.

Excellent talk.

I have a great interest in EventSourcing, but I've always had problems thinking about how I solve the issue with Replays or Versioning events. This talk didn't solve those problems for me, but it definitely pushed me in the right direction to building a stable base to work from.

Not showcasing EventSourcing and CQRS as a silver-bullet for every problem (especially in the PHP circle) was refreshing and opens the door to more libraries/better libraries for managing the CQRS/EventSourcing lifecycle

Very interesting talk. It provided a far more balanced view of benefits and pain points using CQRS than other talks I've seen on the subject.
Also a big thanks for the mini tutorial and examples at the bar afterwards!

As someone new to both event sourcing and CQRS, the material was clearly presented, understandable, and from a real-world point of view, highlighting the many pitfalls of using it. By far the best talk of the day.

A very honest talk about all the pitfalls of running Event Sourcing & CQRS in production. This is a must watch if you're dealing with these type of systems. You could really tell that everything Michiel was speaking about came from experience.
