Embodiment Construction
[0075] The master data center in the embodiment of the present disclosure receives user data sent by multiple slave data centers, wherein the user data sent by each slave data center is user data belonging to a user of the slave data center; the The main data center determines the data type of the user data, wherein the data type includes the first type of user data and the second type of user data, the first type of user data is user data that all users have permission to read, and the The second type of user data is user data that a specific user has permission to read; the master data center synchronizes the first type of user data to each of the plurality of slave data centers.
[0076] Since the embodiment of the present disclosure divides user data into the first type of user data and the second type of user data, since the second type of data is user data that a specific user has permission to read, the first type of user data and the second type of user data are stored ...

The disclosure relates to the technical field of network communication, particularly to a data synchronization method and device in a data center so that a problem of high cost of data synchronization during data synchronization of the data center in the prior art can be solved. According to the embodiment of the disclosure, a master data center receives user data sent by a plurality of slave data centers, wherein the user data sent by each slave data center are ones of a user belonging to the slave data center; the master data center determines data types of the user data, wherein the data types include first type of user data and second type of user data; and the master data center synchronizes the first type of user data to each of the plurality of salve data centers. Because the master data center only synchronizes the first type of user data to the slave data centers instead of synchronizing the second type of user data, on-demand data synchronization is completed with minimum costs during data synchronization of the data center.
Description
technical field [0001] The present disclosure relates to the technical field of network communication, and in particular to a data synchronization method and device for a data center. Background technique [0002] With the development of Internet technology, more and more Internet users are distributed more and more widely. Especially for large Internet companies, most of their users are distributed in a wide geographical area, and more and more large Internet companies are developing their business globally, which makes the network services they provide face a large number of users distributed all over the world. [0003] With the increase of users of Internet companies and the wider distribution of users, Internet companies need to provide multiple data centers in order to better meet user needs. Each data center has multiple users belonging to the data center, and users between different data centers are not completely irrelevant. In order to meet the needs of users, mu...
