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

Abstract

The invention discloses a data synchronization method. Based on a server, data mapping between client data and server data is established in advance; when data synchronization transmission is carriedout, after the client change data of the client is obtained, the server to-be-changed data corresponding to the client change data can be determined according to the pre-established data mapping, so that the change of the server to-be-changed data can be completed according to the client change data. Through the pre-established data mapping of the client data and the server data, the data can be transmitted in a small data block mode without being packaged with the data associated with the data, the data transmission process in the data synchronization task can occupy smaller bandwidth, the stability and fluency in the data synchronization process are improved, and compared with the prior art, the data synchronization method and device are more suitable for data processing requirements ofhigh-level services. The invention further discloses a data synchronization device, data synchronization equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data synchronization method, a data synchronization device, a data synchronization device and a storage medium. Background technique [0002] Data synchronization is a common data processing task in a system or a device. In the existing basic methods, mechanisms such as semaphores and message queues are usually used to transfer data between different processes. A semaphore (Semaphore), sometimes called a semaphore, is a facility used in a multi-threaded environment. It can be used to ensure that two or more critical code segments are not called concurrently. Before entering a critical code segment, A thread must acquire a semaphore, and once the critical code section is complete, the thread must release the semaphore, and other threads that want to enter the critical code section must wait until the first thread releases the semaphore. A "message queue" is a container...

Problems solved by technology

[0003] In existing data synchronization tasks, data transmission is often based on the above two principles, but these basic methods can be easily used in small business areas, but for enterprise-level businesses, only by using these basic methods It can't meet the needs of the business at all, and it will make the logic more complicated and increase more maintenance costs

The reason is that when transmitting data by means of semaphores, in order to ensure the integrity of the data information, it is often necessary to package the changed data and the data associated with the changed data and send them to the receiving end.
