WebSince prefetch mechanisms target different classes of program references, they can be combined to yield a more effective total prefetching behavior; this was explored for the Markov prefetcher ... • Establishing the concept of content-directed data prefetch.- ing. This paper contributes a history-free prefetching method- ology that can issue ... WebDb2 uses prefetch mechanisms such as dynamic prefetch, sequential prefetch, and list prefetch, whenever possible, to avoid costly wait times from synchronous I/O. Prefetch is a mechanism for reading a set of pages, usually 32, into the buffer pool with only one asynchronous I/O operation.
