Description
I'm a co-maintainer of Spring Cloud Sleuth and Micrometer projects (together with Tommy Ludwig and Jonatan Ivanov).
The idea of Micrometer Observation is that you instrument code once but you get multiple benefits out of it - e.g. you can get tracing, metrics, logging or whatever you see fit.
I was curious if there's interest in adding Micrometer Observation support so that automatically metrics, spans could be created and tracing context propagation could happen too. In other words metrics and tracing of this project could be created + if there are Micrometer Observation compatible projects, then they will join the whole graph (e.g. Spring Framework 6, Apache Dubbo, Resilience4j, Apache Camel etc.).
If there's interest in adding that feature, I can provide a PR.
Regardless of whether there's interest in adding this directly to Kafka I would like to discuss what would be the best way to add instrumentation to Kafka. Adding instrumentation means before the message is sent to Kafka I would like to access its headers and be able mutate them, and before the message is received from Kafka I would like to access the headers and retrieve its key-values to create e.g. a span.
