Rebuilding State: To reconstruct the state of an entity (e.g., a user or an order), the service replays events in the order they occurred, which allows it to be flexible when

dapting to changes.

Example: In an Order Service, instead of updating a database record each time an order

status changes, the system records each change as an event (e.g., "Order Created", "Order

Shipped"). To get the current status of an order, you can replay the relevant events.
