Flask-RQ

Flask-RQ is a Flask/Quart extension that background job execution using RQ. RQ allows queueing functions to be run in separate worker processes, allowing long-running jobs to run in the background without blocking the web app from returning a response quickly. Flask-RQ allows configuring RQ using Flask's config, and handles executing jobs in the application context, so other services like database connections are available.
