Saga Choreography
Saga Choreography is a distributed transaction management pattern used in microservices architectures to maintain data consistency across multiple services without relying on a central coordinator. It involves each service publishing events to notify other services of local transaction outcomes, allowing them to react and execute compensating actions if failures occur. This approach promotes loose coupling and scalability by decentralizing transaction logic.
Developers should use Saga Choreography when building microservices-based systems that require long-running, multi-step transactions, such as e-commerce order processing or travel booking workflows, where traditional ACID transactions are impractical. It is ideal for scenarios where services need to operate independently and asynchronously, reducing bottlenecks and improving fault tolerance by handling partial failures gracefully through compensation.
