Problems solved by technology

However, due to the limited resources of the server (such as memory resources, CPU (Central Processing Unit, central processing unit) resources, etc.), the process of "calculating the personalized data matching the request based on the personalized recommendation algorithm" is another one. It is a very resource-consuming process, and the server has other tasks to perform. Therefore, the resources of the server may be exhausted, which affects the stability and avail

Abstract

The present invention provides a data transmission method and device. The method comprises the steps of: after a request message from a client is received, if a server meets a degradation condition, selecting data generated by snapshoot from an assigned storage position; returning the selected data to the client; if the server does not meet the degradation condition, obtaining data matching with the request message; and returning the obtained data to the client. According to the technical scheme of the invention, the data transmission method and device ensure user experience and avoid problemsthat service is overtime, is abnormal and cannot be used. The data transmission method and device can avoid that resources of a server are exhausted and avoid the problem that the server is completely out of use. After the server is recovered, data can be recalculated based on a personal recommendation algorithm, and the degradation process and the automatic recovery process do not need manual intervention so as not to cause large data delay.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data transmission method and device. Background technique [0002] With the increasing development of Internet technology, more and more application scenarios need to use personalized recommendation technology to recommend personalized data to users. For different users, the personalized data recommended is different. Even when a user refreshes the page multiple times, the personalized data recommended to the user will also change. For example, the server uses personalized recommendation technology to recommend items of interest to the user on the home page of the client. [0003] Every time the server receives a request from the client, it will calculate the personalized data matching the request based on the personalized recommendation algorithm, and recommend the personalized data to the client. However, due to the limited resources of the server (such a...
