Problems solved by technology

[0003] The K-DB database in the prior art uses the KSC (K-DB Standby Cluster) architecture that provides core functions such as high availability, data protection, and disaster recovery for the database. Separately synchronize specified table-level, table field-level, or user-level data, and KSC requires that the version and machine configuration of the source and target databases are the same, and requires the use of third-party data synchronization software that is charged and not necessarily adapted. Waste database memory space, data synchronization efficiency is low

Abstract

The invention discloses a method for K-DB database data synchronization. The K-DB database data synchronization method comprises the following steps: a source end database maps the changed target datato a redo log; the target redo log corresponding to the target data is extracted; the target redo log is sent to target end database, the target end database obtains the target data according to thetarget redo log and synchronizes the target data to the second data table. According to the technical scheme provided by the method for K-DB database data synchronization, the version and the machineconfiguration of the source end database and the target end database are not limited, the third-party synchronization software is not needed, only the changed target data is needed, and the memory space of the target end database is saved, and the data synchronization efficiency is improved. The invention also discloses a K-DB database data synchronization device, a system and a storage medium, and has the corresponding technical effect.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular to a K-DB database data synchronization method, device, equipment and a readable storage medium. Background technique [0002] With the development of information technology, enterprises rely more and more on information management. The data information of various business applications is mainly stored in the database, and enterprises have higher and higher requirements for the continuity of these data access. In order to avoid various losses caused by data interruption and ensure data security, real-time data synchronization has become an important method for database management data. [0003] The K-DB database in the prior art uses the KSC (K-DB Standby Cluster) architecture that provides core functions such as high availability, data protection, and disaster recovery for the database. Separately synchronize specified table-level, table field-level, or user-level dat...
