saga-orchestration

Distributed transactions across microservices can be managed using the Saga pattern to coordinate ordered steps and apply compensating actions for rollback. This approach maintains eventual consistency without relying on two-phase commit mechanisms.

Rollback in event-driven microservice workflows is handled through compensation-driven actions triggered by observable state transitions. If a step fails, the orchestrator executes predefined compensating actions to reverse preceding successful operations.

You need saga orchestration for long-running workflows like order processing or travel bookings that require updates across multiple microservices. It is essential when these distributed workflows demand reliable rollback capabilities and eventual consistency.

Yes, you can define per-step timeouts for long-running workflows within a distributed saga. The orchestrator supports configuring ordered steps, corresponding actions, compensations, and timeouts to ensure reliable execution of multi-service updates.

Saga orchestration supports both centralized orchestration and decentralized choreography patterns for cross-service coordination. This allows you to coordinate distributed transactions through a central controller or via event-driven reactions depending on your architecture.

Sagas do not provide ACID isolation; they maintain eventual consistency rather than immediate consistency across microservices. You must explicitly design compensating actions for every step, which increases complexity and requires careful handling of partial failures.
