Title: ACCESSING DATA METHOD AND DEVICE
Abstract:
The present application provides a method and a device for accessing data, which can reduce waste of storage resources. The method comprises: a first cache server sends a first access request to a second cache server, wherein the first access request is used to request first data, and the first access request is from a first edge server; the first cache server receives a copy of the first data returned by the second cache server and a first access frequency, wherein the first access frequency is the frequency of access of the first edge server to the first data recorded by the second cache server; determining, by the first cache server, whether there is a second access frequency lower than the first access frequency, wherein the second access frequency is the frequency of access of the first edge server to the second data recorded by the first cache server, and the second data is cached locally on the first cache server; and if there is a second access frequency, the first cache server caches a copy of the first data.
