saga-orchestration

Distributed transactions in microservices coordinate multi-step workflows across independent services to maintain data consistency. You need them when a single business process requires multiple service updates, such as reserving inventory before processing payment.

Saga orchestration uses a central coordinator to manage state transitions and multi-service workflows, while choreography relies on event-driven communication. Orchestration is preferred for complex business processes requiring explicit step coordination and compensating actions.

Compensating transactions reverse prior steps when a failure occurs in a saga workflow. You implement them by defining counter-actions for each service update, ensuring that if payment processing fails, previously reserved inventory is automatically released.

You manage state transitions by defining saga steps and using a central coordinator to track the execution status of each service. This orchestration ensures reliable workflow execution and triggers compensating transactions if any step fails.

Yes, the saga pattern handles complex e-commerce workflows by coordinating inventory reservation, payment processing, and shipment creation. It ensures data consistency by executing compensating actions to reverse completed steps if the overall transaction fails.

Choreography lacks a central coordinator, making it difficult to track state transitions and debug complex multi-service workflows. For intricate business processes, orchestration provides better visibility and explicit management of compensating actions.
