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)

The invention provides a method and a device for repairing data synchronization abnormality, a medium and a computing device. The method is used for repairing exceptions occurring during data synchronization, after performing data synchronization on the second node based on a first database log in the first node, judging whether the data synchronization between the first node and the second node is abnormal or not, and if so, executing the following repair steps: searching the second node for abnormal data segments whose second data is inconsistent with the first data, and analyzing the seconddatabase log corresponding to the abnormal data segments; and the second node generates a rollback statement according to the relevant information recorded in the second database log corresponding tothe abnormal data fragment, and executes the rollback statement to complete the repair of the abnormal data fragment. The method of the invention solves the problem that the data recorded by the first node and the second node are inconsistent in the data synchronization process, and improves the efficiency and accuracy of the data synchronization.
Description
technical field [0001] The embodiments of the present invention relate to the field of software technology, and more specifically, the embodiments of the present invention relate to a method for repairing abnormal data synchronization, a repair device, a medium, and a computing device. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the development of society, due to work or other needs, many people are using multiple computers at the same time: at home, in the office, or in other secret places. Multiple computers correspond to multiple hard disks, and also correspond to multiple folders. How to synchronize data is a headache for many people. It depends entirely on the U disk to synchronize. After a long time, it is impossible to remember which version is the lates...
