However, with these global instances, there should be a way to close the connections on a graceful shutdown, prior to stopping the worker.
Another use-case would be to make sure that all telemetry is flushed before the host is (gracefully) shutting down.
Is there any existing documentation that I missed which would explain how to do this in Python? If not, could you provide guidance on how this should be implemented?
