Abstract

The present disclosure provides a method for synchronizing data. The method includes: obtaining a first temporary table, which stores modification records for the first data master table within a preset time period; according to the data stored in the first temporary table The modification record of the first data backup table is used for data synchronization; determine whether the first data backup table has successfully completed data synchronization; if it is determined that the first data backup table has not successfully completed data synchronization, then obtain the second temporary table, the second temporary table The operations performed on the first data master table within a preset period of time are stored in it; and the operations recorded in the second temporary table are executed on the first data backup table, so as to realize the data synchronization of the first data backup table. The present disclosure also provides a data synchronization device, an electronic device and a computer-readable storage medium.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a data synchronization method and device. Background technique [0002] In order to achieve data security, data is usually backed up. For example, the primary and secondary databases can be used to back up data. In traditional primary and secondary databases, one is used as the primary database and the other is used as the standby database. On the one hand, this mode will lead to waste of resources, on the other hand, this mode will cause data loss. Contents of the invention [0003] One aspect of the present disclosure provides a data synchronization method for data synchronization between a first database and a second database, the first database stores data through a first data master table, and the second database stores data through a second data master table The master table stores data, and the first database backs up data for the second data master table t...
