Data synchronization method and device, computer equipment, and storage medium

Abstract

The embodiment of the invention discloses a data synchronization method and device, computer equipment, and a storage medium. According to the scheme, when a data synchronization request sent by a client-side account to historical user data of a target business through a terminal is received, multiple pieces of data requested to be synchronized by the terminal are determined, a timestamp corresponding to each piece of data is obtained, then all the timestamps are ranked according to a sequence from the closest to the current moment, a sorting sequence is generated and a plurality of pieces of data are sequentially sent to the terminal according to the sorting sequence, so as to enable the terminal to firstly receive the latest data and provide the latest data for users to use; meanwhile, in the process that the terminal receives the latest data and performs data updating according to the latest data, if the target business generates new data in other terminals, the new data is sent to the terminal, and the terminal completes data updating according to the latest data and then continues to update the data, so that the data synchronization efficiency of terminals can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data synchronization method, device, computer equipment and storage medium. Background technique [0002] With the development of Internet technology, users have more and more terminals. When users use a terminal, it is necessary to synchronize the data generated by the user on the previous terminal to the current terminal to ensure that the user can view the complete data. [0003] The existing data synchronization technology, by recording the created or updated timestamp for each data record, when the terminal needs to synchronize data, sends the timestamp of the last data synchronization to the server, so that the server returns the timestamp after the timestamp according to the timestamp The data. However, the existing data synchronization technology updates data according to the time of innovation or update. When the amount of synchronized data is large, it ta...

AI Technical Summary

Problems solved by technology

However, the existing data synchronization technology updates data according to the time of innovation or update. When the amount of synchronized data is large, it takes a long time to obtain the latest data, and the user experience is poor.

On the other hand, in the process of waiting for the data synchronization of a large amount of data, the data generated by the previous terminal during this period cannot be synchronized in time, and the user needs to perform data synchronization again on the current terminal to obtain this part of the data

At the same time, there is also a lack of corresponding processing mechanism for data abnormalities that occur during the synchronization process, making the synchronization process more cumbersome
