Abstract

Embodiments of the invention disclose a data storage method and device, and aim at realizing decentralized storage of data. The method comprises the following steps of: establishing a node cluster, wherein each node in the node cluster can be network equipment for independently receiving and transmitting data; establishing a first sequence list between the nodes so as to determine a first node anda second node adjacent to each node; when any node in the node cluster undergoes data updating, sending the updated data to other nodes in the node cluster by the node undergoing data updating, so asto ensure that data of any two nodes in the node cluster is the same; and periodically synchronizing data with the first node and second node in the first sequence list by each node, so as to ensurethat the data of 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...
