Abstract

The invention provides a data caching method and device, which are used for solving the problem of low data caching efficiency in the prior art. The method comprises the steps of obtaining a first reading cost used for indicating a time length required for reading one piece of data from a disk, and a second reading cost used for indicating a time length required for reading one piece of data froma preset memory; obtaining a first space occupation amount and an access frequency of each disk file in a plurality of disk files stored on a disk; wherein the first space occupation amount is used for representing the size of the storage space occupied by the hotspot data in the disk file; determining the access cost of each disk file according to the first reading cost, the second reading cost,the first space occupation amount of each disk file and the access frequency; and determining a to-be-cached disk file in the plurality of disk files according to the first space occupation amount andthe access cost of each disk file, and caching the hotspot data in the to-be-cached disk file to a preset memory.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data caching method and device. Background technique [0002] A large number of systems or devices generally store data on disks. However, with the development of the Internet era, data is increasing rapidly. The traditional way of accessing disks to obtain data has been difficult to meet the processing speed requirements of users for systems or devices. [0003] At present, in order to meet the user's demand for processing speed, the developer usually extracts some data from the disk and caches it in the memory manually. However, this method has high requirements for the developer, and requires the developer to analyze the value of the data and understand the space of the memory. The size is more error-prone, which is not conducive to improving the efficiency of data caching. Contents of the invention [0004] The invention provides a data caching method and device to solve t...
