Problems solved by technology

[0004] The inventor found that based on the existing cache file management method, if there are a large number of media resource files invalid within any detection period, the cache server will simultaneously initiate a large number of access requests to the back-end resource server, instantly increasing the number of back-end resources. The load pressure of the resource server may even affect the stable operation of the distributed storage system

Abstract

The cache file management method and device and the server are applied to the technical field of computers, after an access request of a target media resource file is obtained, whether the target media resource file is cached in the server or not is judged, under the condition that the target media resource file is cached, the storage duration of the target media resource file is obtained, and the storage duration of the target media resource file is stored. And determining any duration in a preset duration range as a failure duration threshold value corresponding to the target media asset file, if the storage duration of the target media asset file is greater than or equal to the failure duration threshold value, updating the target media asset file, and feeding back the updated target media asset file. According to the method, whether the target media resource file needs to be updated or not is triggered according to the access request of the target media resource file, update detection is passively carried out on the media resource file, further, the failure duration threshold value of the media resource file is randomly determined within the preset duration range, the failure time of each media resource file is dispersed to a certain extent, and the user experience is improved. Therefore, the instant increase of the load pressure of the back-end resource server is avoided.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a cache file management method, device and server. Background technique [0002] When a user accesses the distributed storage system through the client to obtain a certain media asset file in the system, the client does not directly access the back-end resource server in the distributed storage system, but first accesses the resources set between the client and the back-end For the cache server between resource servers, if the cache server has the media asset file cached in it, the cache server will directly respond to the client’s access request and feed back the corresponding media asset file to the client; on the contrary, if the cache server does not cache the media asset file For the media asset file, the cache server needs to feed back the obtained media asset file to the client after obtaining the corresponding media asset file from the backend resource serve...
