INCREMENTAL DATA SYNCHRONIZATION METHOD, READABLE STORAGE MEDIUM, TERMINAL DEVICE, AND APPARATUS

摘要

The present application relates to the technical field of computers, and in particular, to an incremental data synchronization method, a computer-readable storage medium, a terminal device, and an apparatus. The method comprises: separately obtaining first incremental data from each service subsystem, the first incremental data being user data actually added to each service subsystem within a preset first period of time; aggregating the obtained first incremental data to obtain second incremental data, the second incremental data being user data that should be added to each service subsystem within the first period of time; separately comparing the first incremental data with the second incremental data to obtain a missing incremental record of each service subsystem; and separately adding the missing incremental record to the corresponding service subsystem to complete synchronization of the incremental data of each service subsystem. By means of the present application, consistency between incremental data between service subsystems is ensured.
