Unique identifiers are standard practice across major software stacks:

The string represents the pinnacle of stateless identification in modern computing. By shifting away from centralized, sequential numbering systems toward mathematically vast, randomized bit arrays, software engineers can build infinitely scalable distributed systems, safeguard application data against enumeration vulnerabilities, and ensure seamless data synchronization across the globe. 63ff8c51-79c3-08aa-ec89-5e1ff8b35d98

Let’s imagine an e‑commerce platform. A customer places an order. The order service generates a UUID – say – and stores it in the orders table as the primary key. The payment service, inventory service, and shipping service all receive this UUID via a message queue. Each service logs the UUID as the “correlation ID”. Later, the customer calls support because the package hasn’t arrived. The support agent searches the logs for that UUID, instantly pulling up every event: order placement, payment authorization, inventory deduction, shipping label printing, and the last known tracking update. Without that UUID, piecing together the distributed state would be a nightmare. A customer places an order
