Abstract:
A solution for managing data in which historical execution information for a process is used to determine a set of data requirements for the process. The set of data requirements is then used to move data for the process from a slower storage device (e.g., a magnetic tape) to a faster storage device (e.g., a hard drive) before the process requests the data object (e.g., prefetch). In this manner, the prefetched data can be provided when requested by the process without delaying its execution while the data is moved from the slower storage device to the faster storage device.
