How to emit OTLP traces from traces recorded outside the sdk?

[thediveo]

I would like to export traces using the otlp trace exporter. Now, this exporter uses

opentelemetry-go/sdk/trace/span.go

Line 33 in f39f16c

type ReadOnlySpan interface {

In my use case the spans originate from a different tracing system and there is no way to record using your sdk unless you do a Linux kernel eBPF trace sdk version (now there'sa challenge).

An important ramification is that my spans already have start and end times recorded outside the sdk.

Is there a way to create the sealed ReadOnlySpans in a way where I can set the start and end times to the timestamps that were recorded outside the sdk?

Use the API. You can set a start/end timestamp there.

Sure: WithTimestamp

But this is a SpanEventOption; I need to set the start and end timestamps of the span itself, not of an event touching the span. By the time I am able to create the span, the start and end points in time are already gone some time as I can only create the span after the fact. Does the API support this usage?

Have you read the docs?

WithTimestamp sets the time of a Span or Event life-cycle moment

[thediveo]

Yes, but I missed that after looking at the returned option type, falling for SpanEventOpen referring specifically to span events, not also spans. It might help if you might want to respect that people use different mental models to quickly scan and understand or misunderstand things, in case you care.

Not sure what you actually propose given this is a stable API.
I am not sure why you judge that we are not respecting people especially that we took non-zero effort to help you out 😬
