Event Sourcing and CQRS
The previous chapter, on Domain-Driven Design (DDD), laid the foundation for us to dive into two powerful architectural patterns that answer to the demand for scalable, responsive, and maintainable applications: Event Sourcing and Command-Query Responsibility Segregation (CQRS).
Firstly, we will explore the foundation of Event Sourcing. We will discuss how we can use Event Sourcing to model our domain, how to persist the state of your domain, and how to reconstruct the current state from the persisted events. We will explore the benefits of this approach.
Next, we will turn our attention to CQRS, examining how it separates the responsibilities of commands (write) and queries (read). We will discuss the key components of a CQRS architecture, including the command and query handlers, the domain model, and the event store. We will delve into the benefits of this separation.
As we delve deeper, we will examine the practical considerations of implementing...
