Robust Queue System - HLD
In modern microservices architectures, asynchronous communication plays a vital role, especially when services rely on external clients or systems that take an unpredictable amount of time to process a request.

In this blog, we will explore the design of a queue-based messaging system to handle asynchronous operations between two services, including webhook handling and message processing in a holding queue.
