[0003] However, the existing caching methods usually directly use some specific caching algorithms (such as LRU (Least Recently Used, least recently used) algorithm, LFU (Least Frequently Used, least frequently used page replacement) algorithm, etc.) for caching. The caching method is relatively simple, and the flexibility of caching is low under high concurrency conditions

The application discloses a caching method and device. A specific implementation of the method includes: extracting a plurality of historical data query requests that respectively include query statements and query times; analyzing the extracted query times to determine a plurality of hot spots; For each hotspot time period, count the query statements in the historical data query requests whose query time belongs to the hotspot time period, and determine the hotspot query statement matching the hotspot time period; extract the hot query statement corresponding to the determined hotspot query statement Query results, at the beginning of each hot spot time period, store the query results corresponding to the hot query statements that match the time period in the cache server, and delete the query results in the cache server at the end of the hot spot time period The query results. This embodiment improves the flexibility of caching.
Description
technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a caching method and device. Background technique [0002] With the development of computer technology, the performance of full-text search tools is becoming more and more abundant. In order to improve retrieval efficiency and flexibility, it is usually necessary to cache some retrieval result data. [0003] However, the existing caching methods usually directly use some specific caching algorithms (such as LRU (Least Recently Used, least recently used) algorithm, LFU (Least Frequently Used, least frequently used page replacement) algorithm, etc.) for caching. The caching method is relatively simple, and the flexibility of caching is low under high concurrency conditions. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide an improved caching method and dev...
