OpenTelemetry and Kafka - Create span of Consumer on annotation of Incoming

[arik-dig]

The standard of OTEL for messaging suggests that Spans of Consumer kind should be opened whenever message is consumed.
I see in the quick-guide of kafka (git link) that best practice for consuming messages is to use the annotation of org.eclipse.microprofile.reactive.messaging.Incoming

are you planning to add this kind of instrumentation - Consumer Kind on method annotated with @incoming?

I saw similar discussions like #26353 but nothing related to opening a new span of Consumer Kind

[brunobat]

I Believe this PR has added support for that, no? smallrye/smallrye-reactive-messaging#1678

[radcortez]

Yes, the PR should have proper instrumentation support for messaging, but it is not available in Quarkus yet, I believe.

Can you confirm when are we updating the SmallRye RM version @ozangunalp ?

[ozangunalp]

Yes it is ready to go. But I have been unable to publish to the maven central since a couple of days. Sonatype is having issues.

[arik-dig]

How soon is it going to be part of Quarkus?
I would be happy to be notified somehow when it does happen.
so will you update it in here in this discussion?
or should I subscribe to some other discussion and/or PR?

Thanks

@radcortez , @brunobat are you planning to put attributes of code.funtion and code.namespace based on the annotation org.eclipse.microprofile.reactive.messaging.Incoming ?
it is a common recommended semantic convention
