OpenTelemetry Propagation

[brianmori]

Hi,

I would like to ask if OpenTelemetry support should be part of this library.

When a service A communicate through rabbitmq to service B, service A needs to propagate the "TraceID" and "SpanID" to service B to measure the time needed.

I saw this issue which may help:
open-telemetry/opentelemetry-go-contrib#376

Hey there, by "support should be part of this library", I understand you would like to provide automatic instrumentation, something somewhat similar to e.g. Cassandra instrumentation?

Hi,
I would not add any exporter difference (eg. zipkin) as it is a component to be chosen by the dev team, rather only the propagator to inject TraceId, SpanId in the RabbitMQ headers.

I would avoid to add information to the payload as a checksum is needed in certain scenarios.

There is a discussion to add support for Open Telemetry, but not a short term plan. Let's keep this Issue #43 to track the advancements
