Is it possible to use multithreading with `dataset.map(...)`? I’m currently using multiprocessing via `num_proc`, but it’s too slow as my processing function makes Internet requests.  
Using more threads via multithreading could speed it up, no?

Hi ! I think you’d need to implement the multithreading in the function you pass to `map`
