Abstract

Embodiments of the invention provide a cache expiration time setting method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a first page view of a first type of data stored in the electronic equipment in a first preset time period and a cache hit rate corresponding to the first page view; according to the first page view and the cache hit rate, determining the number of times that the first type of data is read in the permanent memory memory in the first preset time period; and setting the cache expiration time of the target data of the firsttype according to the read times. According to the invention, the cache expiration time can be set according to the number of times that the data is read in the permanent memory; the cache expirationtime is matched with the number of times that the data is read in the permanent memory, so that fine management of the cache data is realized, the reading pressure of the permanent memory is reduced,and the cache space is saved.

Description

technical field [0001] The present application relates to the field of data caching, in particular to a method, device, electronic device and storage medium for setting cache expiration time. Background technique [0002] Nonvolatile memory such as hard disks can store large amounts of data, but reading data from nonvolatile memory is slow. In order to improve the data reading speed, the prior art stores part of the data through a cache capable of high-speed data reading and writing. When it is necessary to read certain data, first try to read the data in the cache, if not, then read the data from the permanent memory storage. Since the storage space of the cache is small, it is necessary to delete data that has not been read for a long time from the cache in time so as to save other data. The existing cache will manage the data stored in the cache by setting a cache expiration time (such as 1 minute), and when a certain data is not read within the cache expiration time, t...
