Abstract

A data prefetch method includes before data is prefetched, a first data access request that is first obtained, and a data prefetch policy that is determined based on the first data access request and a data lifecycle such that a first data set stored in a second storage medium is stored into a first storage medium according to the data prefetch policy. The first data set includes at least one piece of data, the data prefetch policy includes at least a prefetch length, the data lifecycle indicates duration for storing data in the first storage medium, and a read/write access rate of the second storage medium is less than that of the first storage medium.
