Abstract
Described are methods, apparatus and computer programs for managing persistence within a data processing system such as a messaging system, database system or file system. The method for managing persistence includes a deferred evaluation () of at least one criterion associated with costs and/or benefits of saving to persistent storage, instead of persistence behaviour being fully predefined. The evaluation may be performed when a disk write is about to be performed (), or at various times during processing of a data update and at various points within a data processing network. In a messaging solution, the method for managing persistence includes a dynamic evaluation () of costs and/or benefits of saving to persistent storage, with the evaluation being performed at various points in the messaging network after the message has been created and sent by the originating entity. The method includes determining whether message data and/or log records relating to the message require saving to persistent storage, in accordance with the costs and/or the benefits of saving to persistent storage. The benefits of persisting may be determined with reference to a message value ().
