Abstract
The present invention is directed to systems and methods for improved prefetching. The present invention reduces the processing time and associated costs of prefetching by incorporating a number of techniques for efficiently searching a node structure. Such techniques eliminate redundant traversal of nodes. Additionally, such techniques do not require locking the node structure to prevent concurrent updates. Furthermore, such techniques may exploit known key ordering information to optimize a search.
