Provide example of export to multiple backends #532
Description
NB: Before opening a feature request against this repo, consider whether the feature should/could be implemented in the other OpenTelemetry client libraries. If so, please open an issue on opentelemetry-specification first.
Is your feature request related to a problem? Please describe.
It would be nice to point out that you can export traces to multiple exporters, this is handy if transitioning from one vendor/OSS project to another for the tracing backend. You might want to export to both during the transitional phase.
Describe the solution you'd like
An example where tracing is exported to 2 backends or more.
Describe alternatives you've considered
n/a
Additional context
This is with the presumption that it is possible to export traces to multiple backends. I guess with multiple tracer.addSpanProcessor();s?
