[glance] worker, thread, taskflow interplay
We are trying to figure out how these two settings interplay in:
Just setting workers makes a bit of sense, and based on our testing:
=0 creates one process
=1 creates 1 plus 1 child
=n creates 1 plus n children
Are there green threads (i.e. coroutines, per https://eventlet.net/doc/basic_usage.html) within every process, regardless of the value of workers? Does max_workers affect that?
We have read some Glance doco, hunted about various bug reports and other discussions online to get some insight, but I think we're not clear on it. Can anyone explain this a bit better to me? This is all in Rocky.
