Embodiment
[0042] Example: such as figure 1 As shown, a data synchronization system between heterogeneous databases is composed of a configurator, an engine, a historical data synchronization module, a log collection module, a log analysis module, and a data loading module.
[0043] The configurator is divided into two configurations: data resource configuration and service configuration. Data resource configuration can configure the information of the source database and the target database; service configuration is to configure a service to synchronize the data in the specified table in the source database to the specified table in the target database. The information of data resource configuration is used in service configuration. The configuration file after the service configuration is completed will be used by other modules of the system.
[0044] The engine is responsible for starting and stopping historical data synchronization, log collection, log parsing, and data loading.
