Abstract

The invention discloses a data synchronization method based on a cloud technology, and the method can be applied to the field of cloud storage, and specifically relates to data storage and data reading. The method provided by the invention comprises the steps of obtaining a first node information set corresponding to a target node; determining M node scores according to the first node informationset; determining a first upstream node from the M upstream nodes according to the M node scores; and if the first upstream node satisfies the node registration condition, receiving data sent by the first upstream node. The invention further provides a related device, equipment and a storage medium. According to the method and the device, for the learner, each upstream node is scored, the optimal upstream node is screened out according to the node scores of the upstream nodes, and the upstream node synchronizes the data to the learner, so that the data synchronization can be efficiently completed.

Description

technical field [0001] The present application relates to the storage field, in particular to a data synchronization method, a related device, a server and a storage medium. Background technique [0002] With the current development of the Internet, customers on the cloud are paying more and more attention to data security, and a large number of industries have requirements for data storage across computer rooms and regions. In a distributed system, in order to be able to resist failure conditions, data will be saved as multiple copies, and each upstream node of the replication group will save a copy. Among them, the replication group includes a master node (leader) and a slave node (follower), the leader saves the master copy, and the follower saves the slave copy. [0003] When the amount of data read requests is large, more nodes are required to share these requests. If more followers are added to the replication group to undertake data read requests, it will cause a gre...
