Abstract

The present invention discloses a method for data synchronization. The method includes: receiving a request message for synchronizing incremental data sent by a first node, wherein the request message carries a first log serial number, and the first log The serial number is used to characterize the timing of different data in the first node; judge whether the first log serial number is connected to the second log serial number corresponding to the latest data at the current moment of the second node; determine whether the first log serial number continues For the second log serial number, according to the first identification information of the first node that generated the first log serial number, and the time when the first node became the master node successfully matches the corresponding set conditions, based on The request message receives incremental data actively synchronized by the first node. The invention also discloses a data synchronization device and a storage medium.

Description

technical field [0001] The invention relates to data synchronization technology in the field of distributed databases, in particular to a data synchronization method, device and storage medium. Background technique [0002] At present, in the distributed database system, when the primary node fails to provide services normally, the incremental data generated by the primary node needs to be manually synchronized to the database of the standby node, and then re-modify the configuration file and start the application to load business data. In this way, the operation of synchronizing business data between the master node and the standby node is cumbersome, resulting in the standby node being unable to quickly take over the business of the master node, and then the phenomenon of business data out-of-sync between the master node and the standby node occurs, which greatly reduces the distributed database. The reliability of the system is so high that it cannot provide high-performa...
