Data storage system and method, computing device and computer storage medium

Abstract

The invention discloses a data storage system and method, a computing device and a computer storage medium, the system comprises at least two business servers, the at least two business servers comprise data storage modules, and each data storage module comprises a master node data storage module and a slave node data storage module; the master node data storage module is suitable for transmittinga data log to the slave node data storage module; the slave node data storage module is suitable for carrying out legality verification according to the identity information of the master node data storage module carried by the data log, and carrying out data synchronization processing according to the data log after the legality verification is passed; and the master node data storage module isfurther suitable for returning a synchronization success response to the corresponding service server when more than half of the slave node data storage modules complete data synchronization processing. According to the method, the consistency of data storage can be guaranteed, and the reliability, no loss and high performance of the data are effectively guaranteed.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data storage system, method, computing equipment and computer storage medium. Background technique [0002] In the Internet era, users rely more and more on networks and applications. Users store their own data on the servers they visit, such as user IDs, user names, and personal permissions; the servers themselves also save the data necessary to maintain their own operations. For example, startup ports, routing rules, flow control data, third-party addresses, etc., all of which put forward higher requirements for the timeliness, reliability, and consistency of server storage. [0003] In the prior art, server data storage mainly includes server memory storage, server local file storage, and third-party database storage. [0004] However, the inventor found that the prior art has at least the following deficiencies in the process of realizing the present invention: i...

Problems solved by technology

[0004] However, the inventor found that the prior art has at least the following deficiencies in the process of realizing the present invention: in the server memory storage solution, data is mainly stored in the server memory. If the server is shut down or restarted, the cached data will be lost. It will cause very serious problems, such as user data cannot be retrieved again, and memory is limited relative to physical storage, and memory overflow problems are prone to occur

The local file storage of the server is mainly to store the request data in the local file. This solution is a high-performance system architecture, which will use load balancing, such as F5 and Nginx. A request will be distributed to different servers for execution. If the user first The first request to server A performs an operation to save the data, and the second request to server B to obtain the data will result in the inability to obtain the data, and server inconsistency will occur

Third-party database storage. Third-party databases are generally deployed at a single point. The cluster deployment scheme is very complicated, which increases the complexity of the entire system. In addition, remote network communication between the third-party database and the server is required, which has great impact on performance requirements. Not suitable for high service
