DATA SYNCHRONIZATION METHOD, DATA SYNCHRONIZATION SYSTEM, DATA SYNCHRONIZATION APPARATUS, MEDIUM, AND SYSTEM

摘要

A data synchronization method, a data synchronization system, a data synchronization apparatus, a medium, and a system, which relate to the technical field of computer vision. The data synchronization method comprises: acquiring source feature data; partitioning the source feature data to obtain a plurality of pieces of fragment data, and storing the plurality of pieces of fragment data in a plurality of distributed data nodes of a distributed storage system in a one-to-one corresponding manner; establishing a plurality of replica sets corresponding to the plurality of distributed data nodes on a one-to-one basis, wherein each of the replica sets comprises a master node and at least one slave node, and the master node and the slave node are used for backing up the fragment data stored in the distributed data node corresponding to the replica set to which the master node and the slave node belong, so as to obtain master backup data and slave backup data; partitioning the master backup data in the master node of at least one replica set to obtain a plurality of pieces of sub-fragment data; and establishing, in the at least one slave node, a plurality of synchronizers corresponding to the plurality of pieces of sub-fragment data on a one-to-one basis, and synchronizing corresponding data in a slave backup by means of the synchronizers.
