Implementing the Outbox Pattern

The Outbox Pattern addresses the challenge of maintaining data consistency in distributed systems by ensuring atomicity between database operations and message publication. This pattern saves messages to an Outbox table within the same database transaction and later publishes them via a separate process, ensuring at-least-once delivery. Implementation details, such as creating the Outbox table and a processing job using Quartz, are discussed along with considerations for scalability, idempotency, and database performance.
