Abstract

The invention discloses a data synchronization method, which comprises the following steps: obtaining to-be-synchronized data in a source database, and generating a first data change message for the to-be-synchronized data; determining a message theme of the first data change message according to a database table to which the to-be-synchronized data belongs in the source database; Pushing the first data change message into a first message queue which only comprises one partition and corresponds to the message theme according to the message theme; when a trigger condition is met, distributing the first data change message in the first message queue to a first partition of a second message queue according to a preset partition strategy; wherein the second message queue is used for the data synchronization unit to obtain the data change message and synchronize the to-be-synchronized data to the target database according to the data change message. The problem of how to more accurately andquickly synchronize the change data of the source database to the target database is solved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data synchronization method, device and a data synchronization system. Background technique [0002] For industries with huge data scale and diversified business needs, the use of micro-service system to build a data processing system can adapt to the rapidly growing business needs and user volume. An existing data processing system constructed using a micro-service architecture includes a main system and multiple subsystems, wherein the main system processes the basic data based on the main system database used to store the basic data, and stores the main system database As the source database; each subsystem provides business services based on its own independent database, and the subsystem database is used as the target database; after the basic data of the source database changes, it needs to be synchronized to each target database in time to maintain data...
