is there a reason for support for multiple exporters removed?

[onespacer]

^^ as title says. How do I configure multiple exporters jar?

[trask]

hi @onespacer! can you describe your use case, and whether using the otel collector is an option for you?

[onespacer]

@trask I want to export traces to couple of customized backends ex. kafka and splunk. I have created custom exporter jars for those. Couldn't see an option to export them together.

[trask]

makes sense, stay tuned for #2442 (or if you want to go exploring undocumented stuff, check out the current otel.initializer.jar)

[onespacer]

@trask how do I still enable multiple exporters using otel.initializer.jar? I thought "otel.initializer.jar" allows me to create multiple custom exporters, however, only one exporter is active at any given time?

[trask]

hey @onespacer, otel.initializer.jar allows you to add stuff into the agent class loader, so you can add your own SdkTracerProviderConfigurer, and (as many) span processors to the SdkTracerProviderBuilder

this is possible now using the new extension mechanism, please see https://github.com/open-telemetry/opentelemetry-java-instrumentation/tree/main/examples/extension, and let us know if you run into any issues
