Actors can rule your DDD world

on YouTube ↗39m

" summary

Shows using Akka.NET on .NET 6 to host DDD aggregates inside persistent actors, wiring CQRS command routers to per-aggregate actors and projectors for read models. Claims event-sourcing is built in, measures overhead at about 400 bytes per actor, and cites a vendor claim of 50 million messages/sec while reporting over 4+ million/sec on a five-year-old laptop. Demonstrates snapshotting (example: save every 100 events), router pools to scale, and a beer-shipping example that composes and replays domain events.
