| Because the BigQuery client uses the third-party :mod:`requests` library | |
| by default and the BigQuery-Storage client uses :mod:`grpcio` library, | |
| both are safe to share instances across threads. In multiprocessing | |
| scenarios, the best practice is to create client instances *after* | |
| :class:`multiprocessing.Pool` or :class:`multiprocessing.Process` invokes | |
| :func:`os.fork`. | |
