Abstract

The invention relates to the field of data storage, and discloses a cache breakdown prevention method which comprises the following steps: when query requests are received, screening out homologous query requests from the query requests, sending a first query request in the homologous query requests to a local cache, and locking the remaining query requests in the homologous query requests; screening out a heterogeneous query request from the query requests, and judging whether query data corresponding to the heterogeneous query request exists in the local cache or not; and when the query data corresponding to the heterogeneous query request does not exist in the local cache, sending a first query request in the query requests corresponding to the same to-be-queried data labels in the heterogeneous query request to a background database, and locking the remaining query requests corresponding to the same to-be-queried data labels. The invention further provides a cache breakdown prevention device and equipment and a storage medium. According to the invention, the probability of cache breakdown of the background database can be reduced.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a buffer breakdown prevention method, device, electronic equipment and readable storage medium. Background technique [0002] Under normal circumstances, when a user obtains data, the IO unit first goes to the cache to check whether the data required by the user exists. When there is no data required by the user in the cache, the IO unit enters the database to obtain the data. [0003] When multiple users request data that is not in the cache but in the database at the same time, due to the large number of concurrent users, the read cache does not read the data at the same time, and at the same time go to the database to fetch the data, causing the pressure on the database to increase instantly, resulting in cache breakdown. Cache breakdown causes a lot of pressure on the database, affects the speed at which users can obtain data, and even causes server downtime. Contents o...
