Cache data query method and device, equipment and storage medium

Abstract

The invention relates to the field of data caching, and discloses a cache data query method and device, equipment and a storage medium. The method comprises the following steps: collecting data query information uploaded by a client, and constructing a data query key value corresponding to an intermediate database; performing cache anti-breakdown detection on the intermediate database by adopting a database protection method, and judging whether the intermediate database passes detection or not; if the detection is passed, traversing an intermediate database by adopting a data query key value, and judging whether to-be-cached data corresponding to the data query key value is stored in the intermediate database or not; if the to-be-cached data is not stored in the data query key value, obtaining the to-be-cached data corresponding to the data query key value from the original database, and storing the to-be-cached data to an intermediate database; and caching the to-be-cached data in the intermediate database to the cache region to obtain cached data, and sending the cached data to the client. According to the method, the cache data are queried in a data query key value mode, the coupling degree of cache and service logic is reduced, and the operation efficiency of a system is improved.

Description

technical field [0001] The present invention relates to the field of data cache, in particular to a cache data query method, device, equipment and storage medium. Background technique [0002] With the rapid development and popularization of the Internet in recent years, the data visits of some large websites or APPs are also increasing day by day. The number of visits Internet users may have to a website in a certain period of time or during a special event period There will be a sudden increase, which will cause huge access pressure on the background database, and even the problem of data return error, which will lead to the collapse of the website in severe cases. While ensuring high service availability and high-quality user experience, how to reduce request latency and improve system data throughput has always been the focus of the industry. Caching technology effectively reduces the load on the business side and becomes one of the most effective technologies to solve ...
