Application deleting an object - All online replicas in a single cluster are removed immediately after a delete method is executed on an object. (An online replica is one that resides on a cluster node that is on line at the time the delete is issued.) In addition, the cluster remembers the name or UUID has been deleted for 14 days, in the event that one or more nodes holding replicas of the deleted object are off line at the time the delete was issued.
Policy deleting an object - An object can have a storage policy defined by the application and stored along with it. Part of the storage policy might may be an expiration period, beyond which the object is to be removed. In the case of a policy-defined deletion, all replicas, wherever they are stored, are deleted at approximately the same time and become unavailable at most one second after the expiration date and time.
