Saga Client Server Link

Servers (microservices) in a SAGA must implement:

POST /payments/reserve (local transaction) Body: "orderId": "ord-1", "amount": 100 Response: "paymentId": "pay-1", "status": "reserved" saga client server

"userId": 123, "items": ["productId": 456, "quantity": 2], "paymentMethod": "credit_card" Servers (microservices) in a SAGA must implement: POST

The SAGA pattern is a failure-management pattern that helps maintain data consistency across microservices without using distributed transactions (e.g., two-phase commit). In a client-server context, the SAGA pattern defines how a client request triggers a sequence of local transactions across multiple servers, with compensating transactions to undo changes if a step fails. This report analyzes the roles, communication models, coordination strategies, and implementation considerations for SAGA-based client-server systems. "amount": 100 Response: "paymentId": "pay-1"

While the Saga client-server architecture offers many benefits, it also presents some challenges and limitations:

The Saga client-server architecture provided several benefits to ShopEase:

: SAGA shifts the burden of consistency from databases to application logic — specifically, to the server-side components and their compensating actions. Clients must be prepared for eventual consistency and compensation notifications.
