Hey Eric, It so happens that I am literally in the middle of drafting a proposal to the mailing list to integrate with OpenTelemetry on the C++ level. I would fully support having these capabilities for Flight, and I think in the past we've discussed having a contrib directory for such modules, if we don't directly just integrate it into Arrow itself. While gRPC in theory has some of this built in, either way we'd need to expose it (and gRPC uses OpenCensus which is being phased out in favor of OpenTelemetry anyways).
The usecase here is fairly obvious, I think - but it'd be great if we could hear more about how OpenTracing is useful for you/your org. Personally, at my past job, it was a while before people really grasped the value of distributed tracing & structured logging. Also, side note - I've used structlog in Python for JSON logging in the past and it was fantastic, I would definitely recommend that over just dumping JSON into a logger yourself.
