Keep APM<>RUM link when using OpenTelemetry JS tracer

See original GitHub issue

In our web client we use RUM browser SDK alongside an OpenTelemetry JavaScript SDK. This OpenTelemetry tracer instruments fetch requests and appends x-datadog-trace-id and x-datadog-parent-id headers to them in order to link the client request spans with the server spans in APM.

However, when RUM is also enabled in our web client, RUM merges the values of the x-datadog-* headers with its own resulting both values separated by comma. This breaks span linkage on both our APM traces and RUM.

"x-datadog-origin": "opentelemetry-sdk-web, rum",
"x-datadog-parent-id": "12336011929620396511, 8863242246433125602",
"x-datadog-sampled": "1, 1",
"x-datadog-sampling-priority": "1, 1",
"x-datadog-trace-id": "12729276616416176546, 292731172712202065"

Could you consider adding a check so that if any of these headers are already present in the request to no overwrite them?

Thanks 🙇

Hi @bostondv,

What I’m hoping to do is maintain the backend trace link that shows up in RUM when looking a view waterfalls and resources as well as make the link to backend spans in our OpenTelemetry traces when viewing them in APM.

For your use case, a target integration could be to have:

open telemetry SDK tracing requests and sending spans to datadog servers
RUM browser SDK not tracing requests but attaching somehow the trace id generated by open telemetry to RUM events

We definitely plan to have a better integration with open telemetry so we want to address this use case but it is not in our current priorities right now.

We will keep you posted here when we will make some progress on this topic.

I believe this can be closed via https://github.com/DataDog/browser-sdk/pull/1832 which allows browser-sdk to inject w3c context
