Abstract
A device may maintain, in a database, a plurality of data items, each data item of the plurality of data items being associated with a respective category and supplemental information relating to deletion of the data item. The device may associate a group of counters with at least one of the categories and receive a deletion request corresponding to one of the group of categories, the deletion request including the supplemental information. The device may identify a counter associated with the category corresponding to the deletion request based on the supplemental information. The device may then increment the identified counters and selectively delete the data items based on values of the counters.
