Embodiment 1

[0049] like figure 2 As shown, it is a flowchart of a cache elimination method proposed in the first embodiment of the present application. It can be understood that the flowchart in this embodiment of the method is not used to limit the sequence of executing steps. According to needs, some steps in the flowchart can also be added or deleted.

[0050] The method includes the following steps:

[0051] S200, set a first queue and a second queue.

[0052] In this embodiment, the first queue is used to maintain cached data and a unique code (Key) corresponding to each of the data, and the second queue is used to maintain the code and the per-second data of each of the data. query rate. Cache data locally or in the service (the first queue), which can quickly respond to requests.

[0053] see image 3 As shown, it is a schematic diagram of the first queue and the second queue. The first queue and the second queue are both LRU queues. When inserting (Insert), data will be pl...

Embodiment 2

[0072] like Figure 5 As shown, a schematic diagram of a hardware architecture of an electronic device 2 is provided for the third embodiment of the present application. In this embodiment, the electronic device 2 may include, but is not limited to, a memory 21 , a processor 22 , and a network interface 23 that can be communicatively connected to each other through a system bus. It should be pointed out that, Figure 5 Only the electronic device 2 is shown with components 21-23, but it should be understood that implementation of all shown components is not a requirement and that more or fewer components may be implemented instead.

[0073] The memory 21 includes at least one type of readable storage medium, and the readable storage medium includes flash memory, hard disk, multimedia card, card-type memory (for example, SD or DX memory, etc.), random access memory (RAM), static Random Access Memory (SRAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only M...

Embodiment 3

[0077] like Image 6 As shown, a schematic block diagram of a cache elimination system 60 is provided for the third embodiment of the present application. The cache elimination system 60 may be divided into one or more program modules, and the one or more program modules are stored in a storage medium and executed by one or more processors to complete the embodiments of the present application. The program modules referred to in the embodiments of the present application refer to a series of computer program instruction segments capable of accomplishing specific functions. The following description will specifically introduce the functions of each program module in this embodiment.

[0078] In this embodiment, the cache elimination system 60 includes:

[0079] The setting module 600 is used for setting the first queue and the second queue.

[0080] In this embodiment, the first queue is used to maintain the cached data and the unique code corresponding to each of the data, a...

Abstract

The present application discloses a cache elimination method, which includes: setting a first queue and a second queue, wherein the first queue is used to maintain cached data and a unique code corresponding to each of the data, the second queue The queue is used to maintain the code and the query rate per second of each of the data; receive the code of the data to be queried; initiate a query operation to the first queue according to the code, and if the code is not queried The first queue and the second queue are updated during encoding, and the cold data in the first queue is eliminated. The present application also discloses a cache elimination system, an electronic device and a computer-readable storage medium. In this way, hot data sets, warm data sets and cold data sets in the queue can be effectively distinguished, the accuracy of elimination can be improved, and cached data of historical access records can be eliminated without a large number of data accesses.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a cache elimination method, system, electronic device, and computer-readable storage medium. Background technique [0002] The cache elimination algorithm is an elimination algorithm to make full use of cached data. In order to maximize the page hit rate, most operating systems widely use the LRU (Least Recently Used, least recently used) elimination algorithm. The LRU elimination algorithm maintains a queue. The Insert (insert) operation will put the data at the head of the queue, and the elimination will start from the tail of the queue, and the Key (the unique ID number of the data resource) obtained by the Lookup (query) operation will also be updated. , transfer the Key to the head of the queue. The K in the LRU-K elimination algorithm represents the threshold of the number of recent uses, which is an elimination algorithm that only enters the LRU qu...
