Method and device for releasing access pressure of server-side database

Abstract

The invention discloses a method and device for releasing the access pressure of a server-side database. The method comprises the steps that version information of an application in the server-side database is inquired and copied into a shared memory; an application update inquiry request, containing the name and the version information of the application, from a client side is received; the shared memory is inquired, whether the record of corresponding applications exists in the shared memory or not is judged, whether the applications corresponding to the application update inquiry request need to be updated is determined by comparing the version information of the applications if the record of the corresponding application exists in the shared memory, and the applications which do not need to be updated are filtered out; update relevant information of the applications which need to be updated is inquired in the server-side database and is retuned to the client side. According to the technical scheme, due to the fact that the shared memory is arranged at the front end of the server-side database, the inquiry requests of the applications which do not need to be updated are filtered out through the function of the shared memory, the request that the number of the requests of the server-side database is valid is particularly inquired, and the access pressure of the server-side database is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a method and a device for relieving the database access pressure of a server. Background technique [0002] Currently, application software (also referred to as application in this application) with various functions can be installed on smart terminals (such as mobile phones, PCs, PADs, etc.). Moreover, various applications are constantly launching new versions with better functions and more powerful functions, which need to be upgraded on the smart terminal. [0003] Taking the mobile assistant client installed on the mobile phone as an example, the most requested function is to query the upgrade interface. Specifically: the client will send the application name and application version information in the mobile phone to the server from time to time, and the server will compare the version Information to determine whether the client's application needs ...

But starting multiple Redis instances undoubtedly increases the complexity of the system and also increases the cost of maintenance

We have to care about whether the data content between multiple instances is consistent. At the same time, when the multi-instance solution solves the problem of efficient CPU utilization, it greatly wastes system memory resources.
