Problems solved by technology

At the same time, an efficient and reliable data caching system is also needed for the rapid response of Internet applications. An application with a slow response will definitely not be favored by users.
[0003] In the prior art, design methods based on Multi-Paxos algorithm are often used, but because such algorithms are difficult to understand, engineers are prone to make mistakes when writing programs, resulting in system instability; and another design method based on Raft algorithm is in Unsatisfactory in terms of read speed and fault handling speed

Embodiment Construction

[0027] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0028] A schematic diagram of an embodiment of the distributed storage system of the present invention is as follows figure 1 shown. Wherein, master server 101 can process data and store data, and send data to sub-master server and slave server; The election result of the server is switched to the master server, and the system can include multiple sub-master servers; the slave servers 121 and 122 can store data from the master server, provide users with unreliable data, and when the master server is down A new master server is elected, and multiple slave servers can be included in the system.

[0029] In such a system, the main server, sub-master server, and slave server structure are used for distributed storage, and various servers provide data services for users, which improves access efficiency; the sub-master se...

Abstract

The invention provides a distributed storage system and method, and relates to the field of large data storage. The distributed storage system comprises a main server, a secondary main server and a slave server, the main server is used for processing and storing data and transmitting the data to the secondary main server and the slave server, the secondary main server is used for storing the data from the main server and switched to the main server according to election results of the slave server when the main server is down, the slave server is used for storing the data from the main server and providing unreliable data for a user, and a new main server is elected from the secondary main server when the main server is down. According to the system, various servers provide data services for the user, access efficiency is improved, the secondary main server is timely switched into the main server, failure solution efficiency is improved, and stability and reliability of the system are improved.

Description

technical field [0001] The invention relates to the field of big data storage, in particular to a distributed storage system and method. Background technique [0002] With the continuous development of social networks, mobile Internet, and e-commerce technologies, Internet companies operating on the basis of networks are becoming more and more popular. While people use the Internet frequently, they also create a lot of content. These contents are data. Every Internet company basically has a mature and stable distributed system on the back end for data storage, calculation and analysis, and to extract data value. At the same time, an efficient and reliable data caching system is needed for the rapid response of Internet applications. An application with a slow response will definitely not be favored by users. [0003] In the prior art, design methods based on Multi-Paxos algorithm are often used, but because such algorithms are difficult to understand, engineers are prone t...
