Saga Pattern with RabbitMQ
Implement the Saga pattern to manage long-running distributed transactions using RabbitMQ. Orchestrate complex workflows across multiple microservices reliably.
Distributed Transactions Unveiled
In microservices, a single business operation often spans multiple services. For example, placing an order might involve an Order Service, Inventory Service, and Payment Service.
A distributed transaction ensures that all these separate operations either succeed together or fail together, maintaining data consistency across your system.
Beyond Two-Phase Commit
Traditional database transactions often use a Two-Phase Commit (2PC) protocol to ensure atomicity. However, 2PC isn't ideal for microservices because:
- It creates tight coupling between services.
- It can lead to long-held locks, impacting availability.
- It's complex to implement and manage across different technologies.
We need a more flexible approach for distributed systems.
