Example Embodiment
[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples cited are not intended to limit the present invention.
[0033] The present invention provides a real-time synchronization system based on data, which includes a control module, a change capture module, a message queue module, a data synchronization module and a Schema management module,
[0034] The control module defines and starts the synchronization task,
[0035] The change capture module captures the changed data of the source database and encodes the data as a synchronization message according to the synchronization message Schema template, and sends the synchronization message to the message queue module,
[0036] The data synchronization module pulls unconsumed synchronization messages in the message queue module, parses and verifies the syn...
