Abstract

The invention discloses a data synchronization method and device, and relates to the technical field of computer networks, wherein the method comprises the following steps of: reading data from a source database; packaging the read data into a data block; storing the data block in a data block pool, and sending a broadcast notification to multiple threads; and, reading the data block from the data block pool and writing the data block in a destination database by an idle thread receiving the broadcast notification. In the data synchronization method and device disclosed by the invention, due to the parallel processing mode of the multiple threads, the data writing speed is greatly increased; the problem that the data writing consumption time is too long due to the fact that the data writing speed is far lower than the data reading speed can be solved; and the data synchronization efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a data synchronization method and device. Background technique [0002] A database based on distributed file storage is generally written in a specific language and aims to provide scalable high-performance data storage solutions for WEB applications. Due to the limited processing capacity of a single database, in the distributed file storage database solution, based on the source database, multiple target databases are established according to business or function, thereby reducing the access pressure on the source database. When a data table in the source database changes, it is necessary to ensure that the data table in the target database concerned with the data table changes consistently with the data table in the source database. Therefore, a synchronization device is needed to realize the synchronization between the target database and the source database. Synch...
