Problems solved by technology

At present, the relevant solution is to synchronize the full amount of data in the source database to the target database regularly, which can ensure data consistency, but with the increase of data, it will take a lot of time to perform full synchronization each time; or in the On the basis of a full synchronization, only incremental synchronization is performed. The amount of data synchronized each time is small and the synchronization speed is fast. However, some errors may occur during the synchronization process, resulting in data inconsistencies.
[0004] At present, there is no method that can flexibly select the synchronization method according to the actual application situation

Abstract

The invention provides a database synchronization method, device and equipment, and the method comprises the steps: obtaining a first synchronization time point and a second synchronization time point, the first synchronization time point being the synchronization time point of a source data table in a source database, and the second synchronization time point being the synchronization time pointof a target data table in a target database; determining a synchronization time difference value, wherein the synchronization time difference value is the difference between the first synchronizationtime point and the second synchronization time point; and according to the synchronization time difference value, synchronizing the source data table to the target data table in a full-amount synchronization or incremental synchronization mode. According to the method, the source data table is synchronized to the target data table by flexibly selecting a full-amount synchronization or incrementalsynchronization mode through different synchronization time differences, so that the synchronization efficiency can be improved on the premise of ensuring that the data in the target data table is consistent with the data in the source data table.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a database synchronization method, device and equipment. Background technique [0002] With the development of network applications and the accumulation of more and more data, a single database can no longer adapt to the storage and management of explosively growing data. In the ERP application field, with the diversified development of business, the amount of data increases and the types are complex. In order to facilitate data management, developers split the database according to the business subsystem, and split a database into multiple databases. . After the database is split, the joint table query cannot be implemented across databases, so the data in one database needs to be synchronized to other databases that need to use its data. [0003] The two commonly used synchronization methods for databases are full synchronization and incremental synchron...
