METHOD AND APPARATUS FOR HIGH-SPEED DATA QUEUING AND DATA RETRIEVAL

A high speed data queuing and retrieval system includes, in a lower tier, multiple storage devices for storing items for subsequent use by a requesting process, and multiple select devices for retrieving selected items in a pre-specified order from a corresponding storage device according to a requesting process, and, in an upper tier, multiple locally accessible storage devices for temporarily caching those items selected from the lower tier, and a select device for retrieving the selected items from the local storage device and feeding the requested items to the requesting process in a predefined sequence according to the request. The retrieval of the requested items from the local storage device is performed independent from and at a greater speed relative to the temporary caching of the selected items in the local storage device.
