Abstract

The invention discloses a data synchronization method and device, a computer device and a storage medium, and belongs to the technical field of databases. The method comprises: receiving a first change log from any database instance, the first change log comprising a first version value, the first version value is used for indicating a time point when the database instance executes change operation on data, and a data table corresponding to the first change log is determined from a home terminal database instance; and performing data synchronization on the data table according to the first version value. Due to the fact that the time sequence of data change can be determined according to the first version value, when the first change logs from the multiple database instances are received,synchronous processing is conducted on the data according to the first version value in each first change log, and the situation of data inconsistency can be avoided.

Description

technical field [0001] The present application relates to the technical field of databases, in particular to a data synchronization method, device, computer equipment and storage medium. Background technique [0002] With the increase of Internet data business, the application of MySQL database is more and more extensive. The MySQL database (hereinafter referred to as the database) provides a multi-copy master-slave replication mode. Common master-slave replication modes include one master and one slave, one master and multiple slaves, multi-master replication, multi-source replication, etc., so that multiple copies Provide high availability and read-write separation service capabilities. [0003] In implementation, for databases in the master-slave replication mode, users can use the master database instance to perform write operations on the copy of the master database used, and the master database instance will synchronize the data of the write operation to other slave d...
