Saga Orchestration
Saga Orchestration is a design pattern for managing distributed transactions in microservices architectures, where a central orchestrator coordinates a sequence of local transactions across multiple services to achieve a business goal. It ensures data consistency by defining compensating transactions to roll back changes if any step fails, making it suitable for long-running, complex workflows. This pattern helps maintain reliability and fault tolerance in distributed systems without relying on traditional two-phase commit protocols.
Developers should learn Saga Orchestration when building microservices-based applications that require ACID-like consistency across services, such as e-commerce order processing, financial transactions, or booking systems. It is essential for scenarios where services are independently deployed and need to collaborate on multi-step operations, as it provides a structured way to handle failures and maintain data integrity without tight coupling. Use it to avoid distributed transaction pitfalls and ensure system resilience in event-driven or service-oriented architectures.
