Abstract
Embodiments of a system and method to track the locality of a file being restored at the time of prefetching; and a mechanism to dynamically adjust the prefetching parallelism, per read batch, optimally based on the locality and other heuristics, such as system load. A process tracks locality of data elements in a batched data stream, as corresponds to a number of different container IDs accessed by the data elements. The prefetch nominally works serially on the data elements, however, if the locality exceeds a threshold separating acceptable versus non-acceptable distribution of data accesses, each batch is divided into a number of smaller sub-batches that are then pre-fetched in parallel with one another.
