Summary
In this chapter, you learned about the integration of events with CQRS, gaining a comprehensive understanding of how to implement and manage an event-driven architecture in a modular system. You started by exploring the fundamental shift from direct, synchronous communication to asynchronous messaging, emphasizing the trade-offs in terms of consistency, scalability, and fault tolerance. You learned about the distinct roles of commands and events: commands trigger actions that change the state of the system, while events notify other parts of the system about these changes without altering the state directly.
You then learned how to implement CQRS, which separates the responsibilities of reading and writing data. By designing distinct read and write models, you saw how this approach optimizes performance and scalability, allowing you to handle high-traffic systems more efficiently. You also explored different methods of synchronizing these models, from direct database updates...
