Explore how to leverage the actor model in building event-based CQRS systems within Domain-Driven Design (DDD) in this comprehensive conference talk from NDC Porto 2022. Discover the synergy between actors and DDD as Hannes Lowette guides you through implementing such a system using .NET 6 and Akka.NET. Delve into practical code examples covering topics like actor systems, hierarchies, supervision, aggregates, command routing, and projectors. Learn how to handle challenges such as inbox overflow and gain insights into advanced concepts not covered in depth. Suitable for developers with basic knowledge of DDD principles, this talk offers a deep dive into combining actor models with event sourcing and CQRS for more efficient and scalable software architectures.
