Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] Now is the era of data, and ensuring real-time data is a prerequisite for statistics and analysis of business data. In many business scenarios, we may involve data synchronization, which means synchronizing data from a source database to a target database. For example, based on user requirements, in the scenario where the data of multiple housing provident fund management centers needs to be synchronized to the specified target database in real time, the method to realize the data synchronization of housing...

Abstract

The embodiment of the invention discloses a data synchronization method and device, equipment and a storage medium. The method comprises the steps: obtaining incremental data in a past set time interval from a source table in a source database at set time intervals, and writing the incremental data into an intermediate table corresponding to the source table; writing the current time node information and the information of the intermediate table into a control table under the conditions that the incremental data is successfully obtained from the source table and the incremental data is successfully written into the intermediate table; taking the current time node information and the information of the intermediate table as to-be-executed task identifiers, and adding the to-be-executed taskidentifiers into a to-be-executed task queue; writing the incremental data of the intermediate table corresponding to the to-be-executed task in the to-be-executed task queue into a target table corresponding to a target database in sequence. According to the method disclosed in the technical scheme provided by the embodiment of the invention, the data synchronization can be accelerated, the pressure of the source database can be reduced, the real-time performance of the data is improved, and the manual operation cost is reduced.

Description
