What type of bug is this?

Configuration

What subsystems are affected?

Standalone mode

Minimal reproduce step

For example, after jaeger or skywalking is used for instrumentation, their default global ID is uber-trace-id or sw8. After greptimeDB starts call chain tracing, what is the global ID passed? It seems that there is no mention of this in the official documentation.

What did you expect to see?

How can I get the global ID passed inside greptimeDB?

We use the default propagators. So it should be the W3C TraceContext. The specification should mention the ID. I guess it is traceparent.
