Abstract
An example method may obtain a request to delete a plurality of data items satisfying a first condition from a database, and request a retrieval of a first database item from a first predefined storage block associated with the database based on a query including a negation of the first condition. It may be determined whether the first database item is retrieved from the first predefined storage block in response to the requesting the retrieval of the first database item from the first predefined storage block. When it is determined that the first database item is not retrieved, deletion of the first predefined storage block may be requested, else deletion of each one of the plurality of data items satisfying the first condition from the first predefined storage block may be requested.
