saga-orchestration

Distributed transactions across microservices can be coordinated using saga-based workflows, which model multi-step processes and execute reliable compensation paths without relying on two-phase commit. This enables rollback for long-running workflows.

Orchestrated sagas use a centralized coordinator to manage state and trigger each step, while choreographed sagas rely on services reacting to events independently. Both variants are supported for multi-service workflows across domains like order, inventory, payment, and shipping.

Timeouts and rollback in a microservices saga are handled through per-step timeouts and safe compensation chains. If a step fails or times out, the saga executes predefined compensation paths to undo previously completed steps and maintain data consistency.

Idempotent steps in a distributed transaction workflow are implemented by enforcing idempotence at each service endpoint and maintaining centralized saga state tracking. This ensures safely retrying failed steps without duplicating side effects.

Yes, saga orchestration applies directly to order processing, inventory, payment, and shipping scenarios. It coordinates these multi-service workflows by managing state transitions, applying per-step timeouts, and triggering compensation paths when failures occur.

A saga pattern should be avoided when transactions are short-lived and can rely on traditional ACID guarantees, as sagas introduce eventual consistency. Sagas are best suited for long-running workflows where distributed coordination and compensation are explicitly required.
