Actors Can Rule Your DDD World
summary
Shows a weekend prototype called beercenter.net that models DDD aggregates as persistent actors using Aka.NET with command-side event sourcing, snapshots and supervisor strategies. Demonstrates a reusable aggregate interface (checkCommand/applyEvent), a generic persistent actor wrapper, and projectors wired via the actor event bus. Claims high throughput — 50 million messages/sec (4M on a laptop) — and explains routing groups to avoid a single command-router bottleneck. Prototype works functionally but isn’t production-ready.
