Application cache data processing method, device, equipment and system

Abstract

The embodiment of the invention discloses an application cache data processing method, device, equipment and system. The method comprises the following steps: determining a cache space, and dividing the cache space into a hot spot area and a preparation area; receiving a target cache data loading request, and loading the target cache data to the preparation area; judging whether the access information corresponding to the target cache data meets a first access condition or not, wherein the first access condition comprises that the access frequency reaches a preset frequency and the access timeis within a preset range; and when it is determined that the first access condition is met, moving the target cache data to the hot spot area. With application of the embodiment of the invention, theproblems of low hit rate and pollution of the cache due to the fact that the cache is directly moved to the head position of the application cache area can be effectively avoided so that the system performance can be effectively improved.

Description

technical field [0001] The embodiments of this specification belong to the technical field of application cache management, and in particular relate to a method, device, device, and system for processing application cache data. Background technique [0002] In system applications, there are often some data that require fast response and data that may be accessed frequently. Since the application memory is located in the process memory space, its access time is extremely short, so it can meet the above application scenarios. In order to effectively improve system performance, a certain area is usually allocated in the application memory for data caching. However, due to the scarcity of the memory itself, and the main responsibility of the application memory is to support the operation of the application itself, the application cache is usually extremely scarce. [0003] Existing application cache management methods usually use an LRU (Least Recently Used, least recently use...

Problems solved by technology

In this way, the sporadic and periodic data read into the cache and the high-frequency access data that really needs to be cached cannot be effectively distinguished, but are directly read into the head position of the cache, so that while occupying the cache space, the real Part of the hot data is eliminated, resulting in cache pollution and a sharp drop in hit rate
