Unlike the trace data collection, the context propagation mechanism is always on for 100% of requests, regardless of the sampling decisions. In Chapter 4, Instrumentation Basics with OpenTracing, and Chapter 5, Instrumentation of Asynchronous Applications, we have seen that tracing instrumentation APIs, like the OpenTracing APIs, include primitives ...
