CDC and the transactional outbox pattern can be used together in a microservice architecture to ensure that data is written to the database in a consistent and coordinated manner, and that changes to the data are efficiently tracked and propagated to other microservices.

 This can help to improve the performance and reliability of the system as a whole.

 Example use case: When an order is placed, the service records the details of the order in its local database and then sends a message to another microservice that handles shipping.
