> While it is odd for a library to configure OpenTelemetry exporters, there is a reason for this: the actual end-user is unable to configure it directly (as we use the C++ implementation, and the user is likely in Python or R), and often the "important" bits are all in C++, so it would be nice to have a way to dump the information collected.
> On top of that, it would be nice to dump the data in an easily parseable format for further consumption.
> We should enable the ostream exporter, as well as a custom exporter that dumps JSON. See [https://github.com/open-telemetry/opentelemetry-cpp/pull/1111] for an example. See discussion on [https://github.com/apache/arrow/pull/11906] as well.
