What are the benefits and drawbacks of using domain events in aggregate roots?
Domain events are one of the key concepts in domain-driven design (DDD), a software development approach that focuses on the core business logic and domain knowledge of an application. Domain events are things that happen in the domain that are meaningful and relevant to the business, such as a customer placing an order, a payment being processed, or a shipment being delivered. Domain events can be used to communicate changes and trigger actions across different parts of the system, such as other aggregates, services, or external systems.
But how do domain events relate to aggregate roots, and what are the benefits and drawbacks of using them in your technical architecture? In this article, we will explore these questions and provide some practical examples and guidelines for using domain events effectively.
