spring-boot-saga-pattern

Use the Saga Pattern in Spring Boot to coordinate transaction flows across multiple services, ensuring data consistency and reliability through compensating transactions and eventual consistency.

Choreography uses an event-driven approach where services react independently, while orchestration uses a central coordinator to manage the saga flow. Both handle compensating transactions but differ in state management and service coupling.

Implement compensating transactions that reverse previous successful operations. If payment fails after inventory is reserved, the compensating transaction releases the inventory and cancels the order automatically.

You need the saga pattern when a business operation spans multiple microservices requiring atomicity. It maintains data consistency without traditional two-phase commit protocols in decentralized architectures.

Test eventual consistency by verifying state management across services, validating compensating transactions execute during failures, and ensuring error handling triggers appropriate rollback flows in Spring Boot architectures.

Yes, Spring Boot supports event-driven architecture for distributed transactions through the saga pattern's choreography approach, enabling services to publish and consume events that trigger local transactions and compensating actions asynchronously.
