Abstract

The invention is suitable for the technical field of Internet, and provides a data synchronization method and device, a terminal and a storage medium, the method comprises the following steps: obtaining a data chain table corresponding to target data in each distributed node, wherein the data chain comprises a plurality of operation records which are sequentially sorted based on operation time; determining an invalid operation record according to the synchronization identifier of each operation record in the data chain table; and deleting the failure operation record and updating each data chain table. According to the technical scheme provided by the invention, the operation data corresponding to the failed operation record in the data chain table can be deleted, the storage of the failed data is reduced, the storage pressure of the distributed node can be improved, and the storage efficiency is improved.

Description

technical field [0001] The present application belongs to the technical field of the Internet, and in particular relates to a data synchronization method, device, terminal and storage medium. Background technique [0002] In order to improve the convenience of data operation, distributed storage can be used. Users can edit data on multiple different terminal devices, and through timing or quantitative synchronization, etc., to ensure the unity of data and solve the problem of Only operations on the same data require editing operations on one device. The existing data synchronization technology will generate a corresponding operation record every time the data is edited. However, as the number of data editing operations continues to increase, a large number of operation records are stored in multiple distributed nodes at the same time, occupying a large amount of Storage resources reduce the storage efficiency of distributed nodes. Contents of the invention [0003] The e...
