Transactional Outbox Pattern: A Practical Guide to Trade-offs
In event-driven systems, services often need to update local state and publish an event for other services. Doing these as separate operations introduces a consistency risk known as the Dual Write Problem. The core requirement is simple: the database write and event publication should represent one logical change. If one succeeds and the other fails, downstream systems may observe incomplete state. The Transactional Outbox Pattern is a practical way to address this in many microservice architectures. ...
