This repository contains a set of microservices for managing the order process. The system is composed of four services: order-service, customer-service, stock-service, and saga-coordinator.
- Order Processing Microservices
- Architecture
The order process microservices provide a distributed architecture for handling the order placement, payment processing, and inventory management. It follows the saga pattern for managing long-lived transactions that span multiple services.

The order-service is responsible for handling the order placement. It provides APIs for creating new orders, retrieving order details, and updating order statuses. This service communicates with the customer-service and the saga-coordinator to coordinate the order processing.
The customer-service handles the payment processing for the orders. It integrates with external payment gateways to authorize and process payments. Upon successful payment, it notifies the saga-coordinator about the payment status.
The stock-service manages the inventory levels for the products. It provides APIs for updating the available stock quantity and retrieving the current stock status. The saga-coordinator communicates with this service to verify the availability of stock before processing an order.
The saga-coordinator is the central orchestrator of the order processing workflow. It coordinates the interactions between the order-service, customer-service, and stock-service to ensure the consistency of the order process. It handles compensating actions in case of failures or inconsistencies during the transaction.
