Asynchronous data synchronization method and system

The invention discloses an asynchronous data synchronization method and system, which are applied to the field of distributed technology, and the method comprises the following steps: generating a message fingerprint corresponding to a published message, and forming a standard information message corresponding to the message fingerprint; synchronously persisting the message detail data of the published message to a message warehouse; the standard information message is sent to a message receiving device, the standard information message needs to be analyzed by the message receiving device, and an analyzed message fingerprint is obtained; the message fingerprint is sent to the message subscription device, the message subscription device verifies the message fingerprint analyzed by the message receiving device according to the received message fingerprint after receiving a message detail data reading application sent by the message receiving device, reads the message detail data in the message warehouse after v
