Abstract

The invention relates to the technical field of computer vision, and discloses a data synchronization method, a data synchronization system, a device, a medium and a system thereof. The data synchronization method comprises the steps of obtaining source feature data; segmenting the source feature data to obtain a plurality of fragmented data, and storing the plurality of fragmented data in a plurality of distributed data nodes of a distributed storage system in a one-to-one correspondence manner; establishing a plurality of replica sets in one-to-one correspondence with the plurality of distributed data nodes, each replica set comprising a master node and at least one slave node, the master node and the slave nodes being used for backing up fragmented data stored in the distributed data nodes corresponding to the replica sets to which the master node and the slave nodes belong to obtain master backup data and slave backup data; segmenting the main backup data in the main node of the atleast one replica set to obtain a plurality of sub-fragmented data; and establishing a plurality of synchronizers in one-to-one correspondence with the sub-fragment data in at least one slave node, and synchronizing the corresponding data in the slave backup through the synchronizers.

Description

technical field [0001] The present application relates to the technical field of computer vision, and in particular to a data synchronization method, a data synchronization system and devices, media and systems thereof. Background technique [0002] In recent years, with the development of storage technology, easy-to-expand and low-cost distributed storage methods have attracted widespread attention. Considering the reliability of system data when a single storage node fails, usually, a piece of data will be stored on multiple storage nodes. At present, in the case of storing multiple copies, the distributed storage system adopts the form of multi-write for multi-copy writing. Some write failures may cause data inconsistency. Therefore, two-phase commit and other methods are required, which is complex and efficient. lower. Contents of the invention [0003] Embodiments of the present application provide a data synchronization method, a data synchronization system and dev...
