Introduce context propagation API #8161

PerfectSlayer · 2025-01-06T12:54:37Z

What Does This Do

This PR introduce the new context propagation API based on the new context tracking API.
It is similar to the original Agent Tracing propagation API but:

decouples propagation from tracing
allows declaration and registration of multiple propagators, not only tracing
allows using default propagators or specific ones
introduce concerns as a way to distinguish propagators, their features, and their ordering

Motivation

Allows products and feature teams to propagate their own data from / to upstream service without relying on Tracing / Spans / Propagation Tags.

Additional Notes

This PR only introduces the API. Porting the existing Tracing propagation implementation, decoupling product / feature data Tracing data model will come in following PRs.

components/context/src/main/java/datadog/context/propagation/Propagators.java

+import java.util.Map;
+
+public final class Propagators {
+  private static final Map<Concern, Propagator> PROPAGATORS = synchronizedMap(new HashMap<>());


Out of curiosity, why are we not using an IdentityHashMap instead of HashMap?, (if we keep the HashMap it might be good to make Concern final to prevent mistakes)

That’s a good call! I updated the map implementation 👍
