saga-orchestration

Distributed transactions across microservices are coordinated by executing a saga pattern, which manages multi-step workflows and applies compensating actions to roll back failures and maintain data consistency.

Saga orchestration uses a central coordinator to drive step execution and compensations, whereas choreography relies on event-driven reactions across services. This approach supports both variants for distributed transaction workflows.

Cross-service workflows like order processing and inventory reservations handle failure rollback through compensating actions. The saga orchestrator executes defined compensation paths to undo completed steps and ensure data integrity.

A saga pattern is necessary for long-running business processes spanning multiple microservices where single distributed transactions are impossible. It coordinates sequential steps and compensations to handle failures across independent services.

Saga orchestration for payments and fulfillment scenarios can be implemented without external dependencies. The pattern coordinates step execution and compensations natively to manage distributed transactions across independent services.

Saga orchestration limitations include managing complexity in compensation logic and handling partial failures across long-running workflows. Developers must carefully define rollback paths for every step to ensure consistency in distributed transactions.
