Abstract

The embodiment of the invention discloses a data storage method and device for realizing decentralized storage of data. The method in the embodiment of the present invention includes: establishing a node cluster, each node in the node cluster is a network device that can independently send and receive data; establishing a first order list among the nodes to determine the first order list adjacent to each node Node and the second node; when any node in the node cluster updates data, the node where the data update occurs sends the updated data to other nodes in the node cluster, so that the data between any two nodes in the node cluster is the same ; Each node regularly synchronizes data with the first node and the second node in the first sequential list, so that the data between any two adjacent nodes in the node cluster is the same.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data storage method, device, computer device and storage medium. Background technique [0002] In retail stores, there are often multiple cashier terminals, and the data in each cashier terminal should be shared, generally based on the data in the database server, that is, the database server is the central node, and the central node The data in is a shared baseline. [0003] In this way, it is easy to cause that when the central node fails, the data in other cash register terminals cannot be shared and synchronized with the central node in a timely manner, resulting in the failure of normal business development in the retail terminal. Contents of the invention [0004] Embodiments of the present invention provide a data storage method, device, computer device, and storage medium, which are used to realize decentralized storage of data by synchronizing data on e...
