Abstract

A data synchronization method, device and server of a database system, the data synchronization method of the database system comprising: reading a transaction scope consisting of logical change records (LCRs) of a source database; distributing the LCRs corresponding to the same data sheet of the transaction scope to the same thread of multiple threads, the multiple threads being configured to execute the LCRs, such that data synchronization tasks of some or all of different data sheets can be processed concurrently, thus improving data synchronization efficiency of the database system.

Description

technical field

[0001] The present invention relates to the communication field, in particular, to a data synchronization method, device and server of a database system. Background technique

[0002] Since Dr. E.F. Codd proposed the original theoretical model in 1970, the relational database has become one of the essential infrastructures in all information systems, and its importance is second only to the operating system. Today, no large-scale system can be separated from the database. and exist.

[0003] In practical applications, due to the complexity of business logic and the modular design of functions, often multiple sets of databases will be deployed in an information system, and these multiple sets of databases need to cooperate and share data, which requires Ability to synchronize data.

[0004] In order to achieve this goal, all mainstream database vendors have launched their own data synchronization technologies, such as Oracle's Streams and Sybase's Replicatio...
