ABSTRACT:
A system assigns identities to received content portions by determining if the content portion has an assigned content identifier, and if so, applying the assigned content identifier to the content portion received. If the content portion does not have an assigned content identifier, the system selects an unassigned content identifier, from the set of unassigned content identifiers, for assignment to the content portion and assigns the unassigned content identifier to the content portion so that the unassigned content identifier becomes an assigned content identifier in a set of assigned content identifiers. The system associates a persistence metric to the assigned content identifier. The persistence metric indicates an importance of longevity of the assignment between the content portion and the content identifier. The system performs a recover operation to unassign content identifiers in the set of assigned content identifier based on a persistence metric of those assigned content identifiers.
