Answer
A unique identifier passed through all service calls.
In distributed systems, a Correlation ID is a unique identifier injected at the start of a request, typically at the API edge router. It helps track the entire journey of a request as it moves through various microservices. For example, if a user places an order in an e-commerce system, the Correlation ID helps trace the request from the front end through the payment and inventory services.
