My application processes messages from rabbit queue. Lots of the messages are inappropriate for processing (not ideal, but for a valid reason), so the application is just rejecting them upon reading without re-queuing them.
As the messaging library (aio_pika) is otel instrumented, it generates loads of unnecessary spans that are exported. What is the best way to exclude these spans from being exported?

I haven’t found a way to signal this, or mark the current span as “non-recording”.

I’m thinking about:

a) writing a SpanProcessor wrapper that would drop custom marked spans

b) writing custom / patching aio_pika instrumentation to support this filtering

Yet, I hope there is a better way.
I do not want to export the spans and filter them out on the Otel Collector level.

Besides the above mentioned scenario, I have other use-cases, when I’d like to exclude (declaratively or programatically) some spans from flooding the exporter/collector.

Thank you for any ideas.
