Doubt about trace ID

EvanLjp opened this issue 2 years ago · comments

After read the whole codes, I don't find any codes to send the trace ID in the different services. May be I don't find it. Could you share the parts for me? Thanks a lot ~

Hi, if you are referring to context propagation (sending trace id over request headers), we just released that.
Please check out v0.6.0

I guess relates code is here

append_item_to_slice will do writing

Thx a lot, there was no code for that at the time I asked. I would read the related PRs.
