architecture-saga-orchestration

You manage distributed transactions in microservices using the saga pattern to coordinate multi-step business processes. This Skill provides Python templates that track execution states and execute compensating transactions to roll back failures gracefully.

Saga orchestration uses a centralized orchestrator to command cross-aggregate workflows, while choreography relies on event-driven reactions. This Skill provides base classes and templates to implement both patterns for your distributed transactions.

You handle compensating transactions by defining rollback actions that execute when a multi-step business process fails. This Skill manages saga execution states like Compensating and Failed, ensuring data consistency by automatically triggering these defined rollback actions.

Yes, you can use these Python templates to implement an e-commerce order fulfillment saga. The Skill provides example implementations for reserving inventory, processing payment, and creating shipments, with built-in rollback if any step fails.

You need the saga pattern when multi-step business processes span multiple microservices and require guaranteed data consistency. It handles cross-aggregate workflows by replacing ACID transactions with compensating transactions that roll back upon failure.
