Embodiment 1
[0028] In view of the problems existing in the prior art, Embodiment 1 of the present application provides a data access method, which is applied to a network including multiple IDCs. The network may be a distributed network, and each IDC includes a cache cluster and a database. Both cache clusters and databases are used to store user data. by figure 2 It is a schematic diagram of the application scenario of the embodiment of this application. IDC1 can be deployed in Beijing, IDC2 can be deployed in Shanghai, and IDC3 can be deployed in Guangzhou. IDC1 includes cache cluster 1 and database 1, and IDC2 includes cache cluster 2 and database 2. IDC3 It includes cache cluster 3 and database 3. When the user equipment accesses the IDC, based on the location of the user equipment, the server may allocate the access request of the user equipment to IDC1, IDC2, or IDC3. For example, when user equipment 1 visits IDC in Beijing, the server can assign the access request of user equipm...
Embodiment 2
[0061] Based on the same application concept as the above method, the embodiment of the present application provides an IDC, which is applied to a network including multiple IDCs, and each IDC includes a cache cluster and a database, such as Figure 4 As shown, the IDC specifically includes: a storage module 11 configured to record the information between the user identifier and the data version information in the cache cluster when receiving a message carrying the user identifier and data version information from other IDCs. Correspondence; the query module 12 is configured to query the first data version information corresponding to the user ID in the local cache cluster when receiving a data query request message for querying the user data corresponding to the user ID, and query the corresponding The second data version information corresponding to the user identification in the local database; the update module 13 is used for when the first data version information is the s...
