Guidance on Baggage and Context Propagation

[evilpilaf]

I have a set of services that interact mainly with eachother, but for some dependencies (e.g. emailing, OpenAI, etc.) They send requests to external systems. How can we opt in/out context propagation for a subset of downstreams? if all calls are done via httpclient, is there a way to say "only propagate to http://my-domain"?

You need to manually override the propagators and limit the propagation to set of trusted domains. There is no built-in solution that I am aware of. (Unfortunately it is not super easy/documented how to do this..:()
I have seen many users requesting such features in the past as well. Eg: open-telemetry/opentelemetry-specification#1633
