AI Technical Summary

Problems solved by technology

The relational database itself does not support distributed expansion, and the maximum processing capacity of a single database node is limited. When the relational database reaches a certain scale, concurrency problems such as deadlocks are very prone to occur, resulting in a serious decline in its read and write performance

Abstract

The embodiment of the invention provides a database routing method which is applied to a database. The database comprises multiple database nodes. A database routing device is introduced to the method to provide route scheduling of the database, and the method comprises the steps that the database routing device receives a data routing information query request sent by an application, wherein the data routing information query request contains data types; the database routing device determines database nodes corresponding to the data types according to the data types; the database routing device sends data routing information query response to the application, wherein the data routing information query response contains identifier information of the database nodes. The database routing method performs route scheduling of the database by introducing the database routing device so that the relational database can be expanded in a distributed mode. Accordingly, the reading-writing performance of the database is ensured under the situation of increase of a large amount of data.

Description

technical field [0001] The present application relates to a database system, in particular to a database routing method, device and database system. Background technique [0002] A relational database refers to a database that uses a relational model to organize data. The relational model was first proposed by IBM researcher Dr. E.F. Codd in 1970. In the following decades, the concept of the relational model was fully developed and gradually became the mainstream model of database architecture. Simply put, the relational model refers to the two-dimensional table model, and a relational database is a data organization composed of two-dimensional tables and the connections between them. The current mainstream relational databases include Oracle, DB2, MySQL, Inspur K-DB, etc. [0003] With the development of business and the increase of data volume, when the number of users and visits of an application system are increasing day by day, the traditional relational database has ...
