Abstract

The embodiment of the invention relates to the technical field of hot spot data identification, and discloses a heat degree management method based on cached data, a server and a storage medium. The method comprises the following steps: when hitting the data in the cache, judging whether the current access interval of the hitting data is greater than or equal to the preset interval; Wherein, the current access interval is the time interval between the current access time of the data and the previous access time; If the current access interval is greater than or equal to the preset interval, the current decreasing heat degree of the data is calculated according to the preset decreasing heat degree formula; According to the decreasing heat degree of the data, decreasing the heat degree valueof the data to obtain the current heat degree value of the data; Determining a target data queue to which the data belongs according to the current heat value of the data; When the data queue to which the data currently belongs is not the target data queue to which it belongs, the data is transferred to the target data queue to which it belongs. As a result, the hot data can be identified more accurately and the caching efficiency can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of hotspot data identification, and in particular to a cached data-based heat management method, server, and storage medium. Background technique [0002] During the operation of the storage system, data is constantly being cached, and the storage medium in the cache area will gradually become full. Therefore, how to replace the old data with low heat from the cache area to cache new data, so as to ensure the data readability of the entire cache system. The hit rate obtained is a key issue of the cache system. [0003] In the prior art, cache replacement is generally performed based on an LRU (Least Recently Used, least recently used) algorithm. In this cache replacement method, a doubly linked list can be maintained, and the current cache data information can be maintained in the doubly linked list. When new data enters the cache, it will be inserted into the head of the linked list. ...
