Get span by id

[ris314]

Is it possible to get span by id?

Say I get a span with:

import { context, trace } from '@opentelemetry/api';

const currentSpan = trace.getSpan(context.active());

currentSpan has parentSpanId, so I am curious if it would be possible to get the parent span using that id. Essentially something like

getSpanById(currentSpan.parentSpanId)

That's not possible. The parent span could be already ended, exported and garbage collected. Or it could be a even on a different process if it was extracted from http headers.
Note that a span holds only the the span id of it's parent, not an actual reference to it.

Got it, thank you @Flarna
