Passing spanId when starting to create a Span with SDKSpanBuilder

[honho001]

In the SDKSpanBuilder class, when the startSpan function is called. It typically generates the spanId internally.
Is there any way to pass the spanID when starting to create a Span?

There is not. What is your use-case?

I have some servers that will send logs to my Java app. In these logs, there is some information such as globalId, callerId, and localId.
In my Java app i use Otel to collect these logs.
I plan to convert this information as follows:

• globalId to traceId
• localId to spanId
• callerId to parentSpanId

But when I started doing that, I noticed that Otel does not allow me to customize the spanId.
As a newbie to Otel, I'm dn't know if there is a way to achieve my idea.

OTel has very strict requirements for the structure of a span ids, so this isn't something that is supported. Better would probably be to make these attributes of your spans, rather than trying to make them into the otel ids.
