Architecture 41 1.13 Examples 43 Python Module Index Django Q is a native Django task queue, scheduler and worker application using Python multiprocessing. ## Features • Multiprocessing worker pools Django-picklefield Used to store args, kwargs and result objects in the database. • Arrow The scheduler uses Chris Smith’s wonderful project to determine correct dates in the future. • Blessed This number of seconds you want the cache to retain results. e.g. cached=60 #### 1.2.26 scheduler You can disable the scheduler by setting this option to False. This will reduce a little overhead if you're
