The invention relates to the technical field of data synchronization, and provides a data synchronization method and device based on a distributed storage system, equipment and a medium. The method comprises the following steps: when monitoring that a target node stores target data, acquiring historical synchronization data of each adjacent node directly connected with the target node; calculating an evaluation value of each adjacent node according to the historical synchronization data, and screening out the adjacent nodes of which the evaluation values are greater than a preset evaluation threshold to obtain a plurality of first adjacent nodes; traversing the residual storage capacity of each first adjacent node, sorting each first adjacent node according to the sequence of the residual storage capacities from large to small, screening out a target adjacent node of which the residual storage capacity is ranked at the first position, and synchronizing target data in the target node to the target adjacent node, the target adjacent nodes with large residual storage capacity and high synchronization efficiency are scientifically and reasonably selected, so that the data synchronization time of the distributed storage system can be shortened, and the data synchronization efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of data synchronization, in particular to a data synchronization method, device, equipment and medium based on a distributed storage system. Background technique [0002] A distributed storage system is a system composed of a group of computer nodes that communicate through a network and coordinate their work to complete common tasks. [0003] In a distributed storage system, each node is used to calculate or store data, and data synchronization operations between nodes may be required in a distributed storage system. However, in the current distributed storage system, the data synchronization operation between nodes usually has the problem of low data synchronization efficiency. Contents of the invention [0004] The invention provides a data synchronization method, device, equipment and medium based on a distributed storage system to improve data synchronization efficiency. [0005] In a first ...
