I suppose asyncio.to_thread uses concurrent.futures.ThreadPoolExecutor under the hood, so it saves us from getting the running event loop and calling the loop.run_in_executor function . Why don’t we have a similar function for the ProcessPoolExecutor, e.g. asyncio.to_process?

asyncio.to_thread doesn't use ThreadPoolExecutor. Since thread is cheap, the function create a new thread every time. On the other hand, process is not cheap. That's why the only thread has convenient way to run function in. Regards, -- Inada Naoki <songofacandy@gmail.com>
