Problems solved by technology

[0004] However, in the existing cache technology, when the data in the cache is replaced according to LRU, any data accessed in the computer system is cached according to LRU, and the cache performs the same cache operation on any type of data in the computer system , which makes the data of important IO processes in the computer system, such as system file data, have a low hit rate during access, making the execution efficiency of the computer system poor

Embodiment Construction

[0054] figure 1 It is a schematic flowchart of a data cache processing method provided in Embodiment 1 of the present invention. This embodiment can be applied to a computer system, and is used to cache data in the computer system, specifically, as figure 1 As shown, the method of this embodiment may include the following steps:

[0055] Step 101, obtaining the data type of the data to be cached;

[0056] Step 102. Obtain the priority of the data to be cached according to the data type and a preset priority mapping table, wherein the preset priority mapping table includes the data type and the priority corresponding to the data type;

[0057] Step 103, based on the priority of the data to be cached, store the data to be cached in the cache according to the priority, and update the cache queue of the cache;

[0058] Wherein, the cache queues of the cache include cache queues corresponding to each priority, and the cache queues corresponding to each priority correspond to the...

Abstract

The present invention provides a data caching processing method, an apparatus and a system. The method comprises: obtaining a data type of data to be cached; obtaining a priority of the data to be cached according to the data type and a predefined priority mapping table, wherein the predefined priority mapping table comprises the data type and the priority corresponding to the data type; and storing the data to be cached to a cache according to the priority of the data to be cached, and updating a cache queue of the cache. A technical scheme in embodiments of the present invention can perform caching processing on the data to be cached based on the priority of the data type, enable the data with a high priority to remain in the cache for a long period, and thus improve a hit rate in the cache upon high-priority data access.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular, to a data cache processing method, device and system. Background technique [0002] Cache technology is a common technology for data access in computer systems. When a computer system accesses data, it can place the most recently accessed data in the cache. In this way, when the computer system needs to re-access data, it can be stored through the cache. Read data, improve data read and write efficiency. [0003] When the existing cache technology processes the cached data, it usually adopts the least recently used (Least Recently Used, LRU) cache replacement algorithm to process the cached data in the cache, that is, when the computer system accesses the data, the most recently accessed data is kept in the In the cache, the data that has not been accessed for the longest time is replaced out of the cache to ensure that the data cached in the cache is the most recen...
