Use AWS X-Ray id generator with auto-instrumentation

[vmihailenco]

Is it possible to use AWS X-Ray id generator with OpenTelemetry Java auto-instrumentation?

Hey @vmihailenco ,

Did you mean the AwsXrayIdGenerator class?
If this is what you are looking for, you can set a custom IdGenerator by implementing a custom extension that will use the AutoConfigurationCustomizerProvider SPI to modify the SdkTracerProviderBuilder via the AutoConfigurationCustomizer#addTracerProviderCustomizer() method.

Yes, I mean AwsXrayIdGenerator. Any chance OpenTelemetry can provide an extension for AwsXrayIdGenerator?

Ideally, it should be yet another environment variable, e.g.:

export OTEL_TRACES_IDGENERATOR=xray

I wouldn't count on a new OTel-wide env var setting; but I think it's quite possible to have a custom AutoConfigurationCustomizerProvider that sets the generator depending on some configuration flag (e.g. otel.aws-xray.trace-id-generator.enabled or something) in the aws-xray module. Can you create an issue in the contrib repo and ping the aws-xray component owners?

Here is the issue: open-telemetry/opentelemetry-java-contrib#934. I am not sure how to ping the aws-xray component owners...
