Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The invention provides a database access method, referring to figure 1 , in the first embodiment of the database access method of the present invention, the database access method includes:

[0039] Step S10, when receiving the database access request sent by the user terminal, the database proxy node judges whether it is currently within the high-load period of the database server corresponding to the database access request, if not, proceed to step S20, and if yes, proceed to Step S30 is executed;

[0040] refer to figure 2 , is an example diagram of the database topology structure applied by the database access method of the present invention, such as figure 2 As shown in , the database proxy node provides proxy services for multiple database servers at the backend. For any database server at the backen...

Abstract

The invention discloses a database access method, which is applied to a database proxy node. A proxy service is provided for a plurality of database servers at a back end through the database proxy node. The method comprises the following steps: specific to any database server at the back end, if the database proxy node receives a database access request directing to the database server within a high-load time interval of the database server, determining a type of an SQL (Structured Query Language) sentence carried by the database access request firstly, and directly acquiring and transmitting business data directed by the SQL sentence to a source user terminal of the database access request if the carried SQL sentence is a DQL (Data Query Language) sentence; and if the carried SQL sentence is a DML (Data Manipulation Language) sentence, sending the database access request to the database server to execute the database access request when the high-load time interval of the database server is exceeded. The invention also discloses a database proxy node. Through adoption of the database access method and the database proxy node, the working stability of the database servers can be improved.

Description

[0001] technology neighborhood [0002] The invention relates to the technical field of the Internet, in particular to a database access method and a database proxy node. Background technique [0003] With the rapid development of Internet technology, a variety of professional and comprehensive user-centered websites with personalized operations, rich content, and active interactions have emerged, such as various e-commerce websites and microblog websites that have emerged recently. . The above-mentioned user center websites all provide content support through the back-end database server. When a large number of access requests are concurrent in a short period of time, the database server is often unable to execute all access requests in time due to performance limitations, resulting in delayed response, or even downtime and stop services. The problem of low job stability. Contents of the invention [0004] The main purpose of the present invention is to provide a database...
