Across-room multiple-active distributed database management system and across-room multiple-active distributed database management method

Abstract

The invention relates to an across-room multiple-active distributed database management system and an across-room multiple-active distributed database management method. The system comprises a database middleware session proxy cluster, a database storage instance cluster and a middleware bidirectional data synchronization control component cluster. The database middleware session proxy cluster is distributed in different rooms. The database storage instance cluster includes regional clusters arranged in corresponding rooms, and the regional clusters are connected with the database middleware session proxy cluster and the middleware bidirectional data synchronization control component cluster. The middleware bidirectional data synchronization control component cluster synchronizes the data information of the regional clusters in different rooms to ensure the data consistency of the regional clusters. If the database middleware session proxy cluster detects a downtime fault occurring to the regional cluster in the room corresponding to service session data after receiving the service session data input by a user, the service session data is read or written in the regional clusters of other rooms. Normal reading / writing of service session data is not affected by failure of a regional cluster, and the reliability of data reading / writing operation is improved.

Description

technical field [0001] The invention relates to the technical field of distributed databases, in particular to a multi-active distributed database management system and method across computer rooms. Background technique [0002] In the context of big data, distributed databases have become an important means to solve the bottleneck of big data, and how to achieve high availability of distributed databases is crucial to the applicability of distributed databases. With the advent of the "Internet +" era, the amount of data to be processed by the Internet industry is increasing day by day, and the number of concurrent user visits is also increasing rapidly. In order to ensure online services, service providers will give priority to deploying the same system in remote computer rooms. It plays a role of diversion when a large number of users access concurrently. [0003] The traditional cross-computer room distributed database system is to build computer rooms in different areas...

AI Technical Summary

Problems solved by technology

When the database server cluster in a computer room fails, it needs to be powered off for maintenance, and data storage and access services can only be provided after troubleshooting. The traditional cross-computer room distributed database system has the disadvantage of low reliability of data read and write operations.
