I was the lead developer on one for an insurance company a few years back, and it’s still in active use. Insurance is a heavily regulated domain, where an audit trail is more important than performance. There was a natural pattern for it to follow, as we were mapping a stable industry standard.

I also tried doing it in a property setting, where profit margins were tight. The effort needed wasn’t worth the cost, and clients didn’t really care about the value proposition anyway. We pretty much replaced the whole layer with a more traditional crud system.

What did you mean traditional crud as oppose to event-driven arch? How is it relevant to the subject in dicussion?

[blowski]

Event-driven: At runtime, the client tells the system what has happened, the system stores the event and is configured in advance for how to react to it.

CRUD: Imperative. Client tells us to create/update a specific entity with some data.
