Data synchronization method and device, computer equipment and storage medium

Abstract

The invention provides a data synchronization method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a data table marked as irregular synchronization in to-be-synchronized data tables; performing incremental synchronization on the irregularly synchronized data table based on a first update period preset according to historical data; if the incrementsynchronization is invalid, performing incremental synchronization on the irregularly synchronized data table based on a second update period obtained by historical data calculation. According to theinvention, the irregularly synchronized data tables in the database are synchronized in a targeted manner; according to the method, reasonable management of the irregularly synchronized data table synchronization period in the database table is achieved, the synchronization performance and efficiency of the database are improved, the situation that the operation burden of a server is increased due to the fact that the irregularly synchronized data table is frequently synchronized is avoided, and meanwhile the real-time performance of database data is guaranteed.

Description

Technical field [0001] The present invention relates to the field of mobile communications, and in particular to a method, device, computer equipment and storage medium for data synchronization. Background technique [0002] Before the incremental synchronization of the database, the entire amount of data needs to be copied, and the synchronization time point of the entire amount of data and whether the data has been changed are automatically determined to determine whether to perform incremental synchronization. Although compared to full synchronization, incremental synchronization is very beneficial for saving storage space, but incremental synchronization is temporarily unable to achieve targeted synchronization based on the characteristics of data tables in the database. [0003] Specifically, the prior art cannot synchronize data in time with respect to the update cycle of the data table, resulting in the period of incremental synchronization being inconsistent with the update...

Although incremental synchronization is beneficial for saving storage space compared to full synchronization, incremental synchronization cannot achieve targeted synchronization based on the characteristics of the data tables in the database

[0003] Specifically, the existing technology cannot synchronize data in time according to the update cycle of the data table, resulting in the inconsistency between the cycle of incremental synchronization and the update cycle of the data table. However, if the cycle of incremental synchronization is too short, it will increase the operating burden of the server and increase the If the volume synchronization period is too long, it will be difficult to ensure the timely update of the database
