Problems solved by technology

[0003] Existing real-time synchronization tools for commercial or open source databases have relatively high cost of use and threshold for operation and maintenance. Instead of using third-party tools, implementing multi-active databases through homologous multi-write transformation is very costly for stock applications. The business layer The scope of changes is wide, and the risk of abnormalities is relatively large

Abstract

The embodiment of the invention provides a database data synchronization method and device, and the method comprises the steps: determining a corresponding data synchronization task and task triggering time corresponding to the data synchronization task according to the feature information of a target data table in a source database; synchronizing the target data table to a target database according to the task triggering time and the data synchronization task. According to the method and device, data synchronization operation of the main and standby databases can be conveniently, effectivelyand accurately realized.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a database data synchronization method and device. Background technique [0002] Multi-park hot standby deployment of traditional relational databases is the core foundation for many enterprise stock applications to achieve high-availability architecture, involving data synchronization mechanisms between parks. [0003] Existing real-time synchronization tools for commercial or open source databases have relatively high cost of use and threshold for operation and maintenance. Instead of using third-party tools, implementing multi-active databases through homologous multi-write transformation is very costly for stock applications. The business layer The range of changes is wide, and the risk of abnormalities is relatively large. Contents of the invention [0004] Aiming at the problems in the prior art, the present application provides a database data synchronization me...
