Abstract
This application discloses a data prefetching method, including: receiving, by a home node, a write request sent by a first cache node after the first cache node processes received data; performing, by the home node, an action of determining whether the second cache node needs to perform a data prefetching operation on the to-be-written data; and when determining that the second cache node needs to perform a data prefetching operation on the to-be-written data, sending, by the home node, the to-be-written data to the second cache node. Embodiments of this application help improve accuracy and certainty of a data prefetching time point, and reduce a data prefetching delay.
