Abstract: A method and apparatus for managing keys pertaining to data objects are disclosed. In the method and apparatus, a plurality of keys that are associated with a plurality of data objects are retained, whereby the plurality of keys are capable of being listed in accordance with an ordering scheme. The ordering scheme is used to inspect the plurality of keys to determine whether a data object associated with a key of the plurality of keys satisfies a criterion. One or more actions are taken on the key or associated data object based at least in part on determining that the criterion is satisfied, whereby an order of taking the one or more actions is a reverse of an order by which the key is listed in accordance with the ordering scheme.
