saga-architecture

Coordinate distributed transactions using the saga pattern to ensure eventual consistency. It manages multi-service workflows by defining participants, specifying compensating actions for each step, and handling timeouts and retries.

Manage failure recovery and safe rollback across services by defining compensating actions for each saga step. This ensures that if a workflow fails midway, previous steps are systematically reversed to maintain data consistency.

Choose orchestration for a central coordinator managing saga participants, or choreography for event-driven coordination. Your choice depends on whether you need centralized control or decentralized event reaction for your distributed transactions.

Saga steps must be idempotent to safely handle retries without duplicate side effects. Persistent saga state is maintained throughout the workflow to track progress, manage timeouts, and ensure reliable recovery during cross-service operations.

Use the saga pattern for multi-service workflows like order processing, inventory, payment, and shipping where ACID transactions are unavailable. It coordinates distributed operations and guarantees eventual consistency through compensating actions.

Define your saga participants, choose choreography or orchestration, specify compensating actions for each step, and trigger the saga with an initial event. This begins the coordination and ensures safe rollback if failures occur.
