Data processing method, device and system, electronic equipment and computer storage medium

Abstract

The embodiment of the invention provides a data processing method, device and system, electronic equipment and a computer storage medium. The data processing method comprises the steps that receivingend equipment to be subjected to data synchronization receives a database log sent by sending end equipment, wherein the database log carries state information used for indicating the state of the database log; the receiving end equipment acquires the state information in the database log, and carries out disk falling operation on the database log and modifies the state information of the databaselog into state information of a preset state so as to determine that the database log with the modified state information is not sent back to the sending end equipment according to the state information of the preset state. According to the embodiment of the invention, the problem of data loopback caused by bidirectional data synchronization at different positions by using a system for providingservices for multiple activities in different places is avoided, and the generation of invalid traffic is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a data processing method, device, system, electronic equipment, and computer storage medium. Background technique [0002] Multi-Master is an advanced service in the field of database and storage. It provides read and write capabilities through database services or storage services deployed in multiple geographical locations, and the bottom layer synchronizes data with each other. For example, a database service is deployed in A, and it can also be deployed in B, C, D, etc., and the database service deployed in these locations can provide the business with local (local) read and write capabilities. [0003] Taking the database service deployed at A and B as an example, both A and B provide businesses with the ability to read and write the database service locally. If there is a data change in A, through the data synchronization service between A ...

Problems solved by technology

Therefore, on the one hand, for the sender, it is necessary to record a large number of database instance ids and comparison logic; on the other hand, the sender needs to record the information of each database instance, resulting in the aggregation of a large amount of data traffic; on the other hand, The database instance id cannot be changed

[0006] In short, the data synchronization method of the existing remote multi-active system will lead to a large amount of invalid data and invalid traffic for database services or storage services between different geographical locations (for example, between A and B), and there is a lack of database instances Processing flexibility
