Kafka Springboot Auto Instrumentation

[urwah1996]

Hi!
We are using opentelemetry spring boot autoconfigure sdk to bring tracing to our microservices. We have included the sdk as a dependency. As of now it is instrumenting http calls and rest template client calls to downstream services.
We are using Kafka messaging heavily in our microservices. I came across open telemetry instrumentation for kafka clients. This instrumentation will require manually wrapping the kafka consumers and producers with TracingConsumer and TracingProducer respectively.

I wanted to know if it is in the pipeline to autoconfigure TracingProducer and TracingConsumer during spring boot application startup. Just like spring cloud sleuth has post processors for producer and consumer

Any kind of help or direction would be really appreciated!
Thanks :)

Spring-kafka has the RecordInterceptor and BatchInterceptor interfaces that I believe would provide better instrumentation than the plain kafka-clients one (and we already have a spring-kafka javaagent instrumentation that uses BatchInterceptor; perhaps it could be refactored to a library+javaagent instrumentation).
I don't think we have this in the pipeline, but any help with that would be very much appreciated.
