Leek is a Redis-backed distributed scheduler for celery. Because it stores task execution data in Redis, it can safely be run on multiple nodes without duplicating work. Unlike other distributed schedulers which use locking to prevent more than a single instance from running simultaneously, all leek nodes are running all the time; they compete to generate the next invocation of a scheduled task, and only one node will successfully do so. This means automatic failover in the event of a node outage.

To install:

python setup.py install

To use:

celery beat -S leek.LeekScheduler
