incompatibility with AWS XRay (via OpenTelemetry collector)

[errordeveloper]

I just thought it might be useful for folks to be know that the kspan trace IDs are currently not compatible with AWS XRay: open-telemetry/opentelemetry-collector-contrib#5257 (reply in thread)

Thanks for the report.
Shouldn’t that be filed as an XRay incompatibility with OpenTelemetry?

It is feasible to change the scheme kspan uses, at the cost of losing trace continuity across a restart of kspan. Or add some persistence mechanism to cover the restart.

I updated the title.

Yes, it's neat to have restart persistence by the virtue of consistent hashing. Maybe someone could think of this as a separate mode. By the way, very similar use timestamps seems to be mandated by the W3C spec also...
