Simulation Details

OrderSystem is a mid-sized e-commerce company that processes 50,000 orders daily, with traffic surging to over 200,000 during seasonal sales. However, its synchronous REST-based backend infrastructure struggles under high-traffic conditions, leading to critical failures during events like Black Friday. The most recent sale resulted in over 15,000 unprocessed orders, including high-priority expedited shipping orders, causing severe customer dissatisfaction and tarnishing the company’s reputation. Competitors like ShopEase and MegaMart, who use asynchronous architectures, demonstrated resilience and uninterrupted service during the same period.

To regain its competitive edge, OrderSystem is transitioning to an asynchronous order processor with message-driven processing, priority-based routing, and retry mechanisms. This upgrade aims to reduce order processing time by 30%, achieve 99.9% data integrity, and ensure operational resilience during peak traffic. Success is essential for restoring customer trust and positioning OrderSystem as a scalable and reliable player in the e-commerce industry.

You will step into the role of a Backend Developer tasked with implementing critical upgrades to OrderSystem’s backend infrastructure. Collaborating closely with Priya Malhotra, the Lead Software Engineer, your mission is to refine the routing logic and error-handling mechanisms in the OrderProcessor.java file. Specifically, you will:

– Implement the routeByPriority(Order order) method to ensure high-priority orders are always processed successfully and normal-priority orders are handled probabilistically.
– Develop retry mechanisms to address transient failures, ensuring failed orders are reprocessed efficiently and data integrity is maintained.
– Create the getOrderStats() method to provide real-time insights into processed, failed, and pending orders.

Priya will provide concise feedback and guidance, referencing best practices to ensure your work aligns with the architectural vision. While supportive, she expects high-quality results and precise implementation to meet the project’s objectives.

To complete the simulation, you need to:
– Collaborate with Priya Malhotra through real-time chat to refine and implement the routing logic and retry mechanisms.
– Edit the OrderProcessor.java file to ensure priority-based routing and robust error handling.
– Ensure the asynchronous processor meets performance benchmarks, including correct routing, retry strategies, and real-time system statistics.
– Demonstrate operational resilience by ensuring the system can handle simulated high-traffic scenarios without bottlenecks or data loss.
