It opens the file in the main thread, and not asynchronously, but doesn't the file itself get read in the other thead, asynchronously? And is there any extra RAM used?
The file could be on an external network drive and so opening it may block the main thread for seconds: ``` with open(the_path, 'rb') as the_file: # no other tasks can progress while opening this file return await asyncio.to_thread(json.load, the_file) ```
Also -- and this may be completely my ignorance -- but don't you need to wrap the json reading in a function anyway so that you can capture the result somewhere?
asyncio.to_thread is an async function that returns the result of the passed in synchronous function, and can run concurrently with other tasks by scheduling the synchronous function on a thread
In short -- no, I don't think JSON is not special enough to get a Path method, but a simple way to read JSON directly from a Path would be nice.
``` asyncio.to_thread(json.loadf, the_path) ``` would be fine too
