celery.events.snapshot

celery.events.snapshot

Consuming the events as a stream is not always suitable so this module implements a system to take snapshots of the state of a cluster at regular intervals. There is a full implementation of this writing the snapshots to a database in djcelery.snapshots in the django-celery distribution.
