Cloned from launchpad blueprint https://blueprints.launchpad.net/horizon/+spec/background-async-job-engine.

Description:

Horizon needs a background job engine. there are various scenarios in larger scale implementations where the series of api calls required to complete a task will result in a latency that is outside a nominal time-frame for decent user interaction experience. we need a job engine in place for these scenarios. Celery is the most immediate choice, but there could be other packages worth considering as well
