| description | The invention discloses a single-source multi-node data synchronization method and system, and relates to the field of data synchronization. The method comprises the following steps: establishing a change data table through a trigger, inserting a plurality of change data into the change data table, respectively reading the plurality of change data through a plurality of nodes, and selecting to-be-synchronized data in the change data for synchronization. According to the method, multiple change data in the change data table are read through multiple nodes; and to-be-synchronized data in the change data are selected for synchronization, so that trigger data of only one data source is generated. Therefore, the data can be synchronized to any node, the timeliness of data synchronization is considered, and junk data generated by a database and the pressure of the database are reduced.
