Package brave.propagation.stackdriver

Class StackdriverTracePropagation

java.lang.Object
brave.propagation.stackdriver.StackdriverTracePropagation
All Implemented Interfaces:
brave.propagation.Propagation<String>
public class StackdriverTracePropagation extends Object implements brave.propagation.Propagation<String>
Stackdriver Trace propagation.

Tries to extract a trace ID and span ID using the B3 key set, such as X-B3-TraceId, X-B3-SpanId, etc. If not present, tries the x-cloud-trace-context key.

Uses B3Propagation injection, to inject the tracing context using B3 headers.
