Abstract
The present disclosure relates to data access methods and apparatus. One example method includes sending, by a first cache server, a first access request to a second cache server, where the first access request is used to request first data, and the first access request is from a first edge server, receiving, by the first cache server, a copy of the first data and a first access frequency that are returned by the second cache server, where the first access frequency is a frequency at which the first edge server accesses the first data and that is recorded by the second cache server, determining, by the first cache server, whether a second access frequency lower than the first access frequency exists, and in response to determining that the second access frequency exists, caching, by the first cache server, the copy of the first data.
