Gunicorn--how to kill a worker if the client closes their connection?
I've got a flask app running under gunicorn which handles client requests via REST api with an extremely CPU-intensive backend; some requests take minutes to respond to.
But that creates its own problem. If I, say, run a little script to make a request and kill it (ctrl-C or whatever), the flask app keeps on running despite the fact that no one will hear it when it comes back from the depths of computation and gets its broken pipe.
Is there a way to terminate the API call (even just kill/restart the worker) as soon as the client connection is broken? That feels like a thing Gunicorn could handle, but I'm powerless to find any setting that would do the trick.
Thanks--this has been vexing me!
