Context Propagation and Baggage
Dive deep into context propagation, a key OpenTelemetry concept for linking distributed operations. Explore how baggage can carry arbitrary data across services.
Linking Distributed Operations
In modern applications, a single user request often travels through many different services. Imagine an online store: your click goes to a frontend, then an order service, a payment service, and a shipping service.
How do we track this journey? If each service logs independently, it's like trying to follow a single thread in a tangled ball of yarn!
What is Context Propagation?
Context propagation is the magic that links these distributed operations together. It ensures that all parts of a request, no matter which service they touch, share a common understanding of that request.
Think of it like a relay race: the 'baton' (the context) is passed from one runner (service) to the next, linking all their efforts to a single goal.
