Abstract

The embodiment of the invention relates to the technical field of databases, in particular to a database synchronization method and a database synchronization device, which are used for improving the initialization efficiency in a data synchronization process of a target database. According to the database synchronization method and the database synchronization device, a total data request message is sent to a source snapshotting server by a target server, determined total data information is sent to the target server by the source snapshotting server, so that a total data snapshotting document is obtained by the target server according to the total data information, and the total data snapshotting document is led into the target database, and thus, the initialization process of the target database is finished, thereby realizing automatic initialization control in the data synchronization process of the target database and improving the initialization efficiency in the data synchronization process of the target database.

Description

technical field

[0001] The embodiment of the present invention relates to the technical field of databases, in particular to a database synchronization method and device. Background technique

[0002] E-commerce is becoming more and more popular, and the data volume of real-time transaction systems is also increasing day by day. However, the processing capacity of a single database is limited. Therefore, it is necessary to establish multiple target databases based on the source database according to business or function, so as to reduce the access pressure on the source database. When a data table in the source database changes, it is necessary to ensure that the data table in the target database concerned with the data table changes consistently with the data table in the source database. Therefore, a synchronization device is needed to realize the synchronization between the target database and the source database. Synchronization of data between source databases. [0003...
