Abstract
Improving read performance using pre-fetches by encoding an extent map provided by an application executed on a client, where the extent map identifies valid data of the file as extents that may be interspersed with holes constituting invalid data. A server-based filesystem interprets the extent map as a read receipt to bring the right extents in memory ahead of a read request. The extents of the extent map are prefetched at a prefetch read horizon. Because the client is aware of the application-resident extent map, the prefetch operations can intelligently skip over the holes. Multi-stream restores using multiple streams to issue read-ahead operations for the pre-fetches in parallel can also be accommodated.
