OpenTelemetry Client Libraries

[bvinayakumar]

Hello,

As per Jaeger documentation, OpenTelemetry (https://www.jaegertracing.io/docs/1.22/opentelemetry/) is currently in experimental state.

Are there any supported Jaeger client libraries available (or under development) for OpenTelemetry that I can experiment with?
I am particularly looking for Java and Node.js client libraries.

Kind regards,
Vinaya

With OpenTelemetry, you would use the OpenTelemetry client libraries to emit OTLP spans to OTEL collector which can then export into Jaeger:

java: https://github.com/open-telemetry/opentelemetry-java
node.js: https://github.com/open-telemetry/opentelemetry-js

It seems you can emit Jaeger spans too (java, node.js) which you could send straight to Jaeger's collector.

That page is about the experimental backend components that use OpenTelemetry Collector as the base. As @albertteoh mentioned, the OpenTelemetry client libraries can be used to send spans both to Jaeger directly, as it's a requirement stated in the spec: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/library-guidelines.md#requirements
