Parameters:
|
|
workers: number of workers to assign the thread pool when the event loop is
|
|
started. Defaults to `None`, which, when passed to
|
|
ThreadPoolExecutor, will by default use 5x the number of available
|
|
processors on the machine (which the docs claim is a reasonable
|
|
assumption given threads are more commonly leveraged for I/O work
|
|
rather than intense CPU operations). Given the intended context for
|
|
this class, this assumption aligns appropriately.
