A repair method, repair device, medium and computing equipment for abnormal data synchronization

Abstract

The invention provides a repair method, a repair device, a medium and a computing device for abnormal data synchronization. Wherein the method is used to repair the abnormality that occurs during the data synchronization process, and after the data synchronization of the second node is performed based on the first database log in the first node, the data between the first node and the second node is judged Whether there is an abnormality in the synchronization, and if there is an abnormality, the following repair steps are performed: find the abnormal data fragment whose second data is inconsistent with the first data in the second node, and parse the second database log corresponding to the abnormal data fragment; and The second node generates a rollback statement according to the relevant information recorded in the second database log corresponding to the abnormal data segment, and executes the rollback statement to complete the restoration of the abnormal data segment. The method of the invention solves the problem of inconsistency of recorded data between the first node and the second node in the process of data synchronization, and improves the efficiency and accuracy of data synchronization.

Description

Technical field[0001]Embodiments of the present invention relate to the field of software technology, more specifically, embodiments of the invention relate to a repair method, a repair device, a medium, and a computing device of data synchronous abnormality.Background technique[0002]This section is intended to provide background or context of an embodiment of the invention as stated in the claims. The description herein is not because it is recognized in this section.[0003]With social development, many people use multiple computers at the same time because of work or other needs: home, office, or other secret place. Multiple computers correspond to multiple hard drives, and also correspond to multiple folders. How to synchronize data synchronization is a problem with a lot of people's headaches, completely rely on the U disk to synchronize, time long can't remember which version is the latest, which version needs to be modified, to finally, the wrong file is also often happening, t...

Problems solved by technology

[0007] However, in the existing technical solutions for solving the data synchronization delay between the master and the slave (or between multiple nodes), the synchronization error is skipped, and the problem of the synchronization delay is solved by a method of uninterrupted synchronization. The solution has the risk of slave data loss, which can easily cause data inconsistency between the master and the slave (or between multiple nodes)
