Abstract

The invention discloses a data synchronization method, device and system. The method comprises the steps of receiving a first request of client equipment, wherein the first request carries a channel identification ID reflecting a channel type; determining a channel type corresponding to the channel ID according to the channel ID, the channel type including one of a first channel supporting transmission of full data, a second channel supporting transmission of incremental data, and a third channel supporting transmission of full data and incremental data; and determining a data reading mode according to the channel type, reading data from a preset database according to the data reading mode, and sending the read data to the client device. The technical problem that different types of data cannot be synchronized through the same data channel service in the prior art is solved.

Description

Technical field [0001] This application relates to the field of computer technology, and in particular to a data synchronization method, device and system. Background technique [0002] At present, data synchronization is usually achieved between databases through full data synchronization, incremental data synchronization, and full incremental data synchronization. Due to the full data synchronization and incremental data synchronization, there are some aspects of data reading methods and data formats. Therefore, various existing database products often adopt different implementation schemes in the process of realizing full data synchronization and incremental data synchronization. [0003] For example, for full data synchronization, you need to use the full data channel, for incremental data synchronization, you need to use the incremental data channel, and for the full and incremental synchronization scenario, you need to record the current time or the position of the incrementa...
