The Event Sourcing pattern is a software architecture pattern where changes to an application's state are stored as a sequence of events. Instead of storing the current state of data directly (like in traditional CRUD systems), each state change is recorded as an immutable event, and the current state is reconstructed by replaying these events. This approach offers many advantages, particularly for complex applications that need to keep detailed histories of state changes.

In event sourcing, you’d store the events that happened to change the state of the order. You could materialize the current state of the order by replaying those events.
