Cache data management method and device, storage medium and electronic equipment

Abstract

The invention discloses a cache data management method and device, a storage medium and electronic equipment, and relates to a cache management technology. According to the specific scheme, the methodcomprises the steps of obtaining an instruction and interpreting an instruction type; when the instruction type is a data query instruction, obtaining a data address and a category identifier of theto-be-queried data; judging whether to-be-queried data exists in the cache region or not according to the data address and the category identifier, acquiring the to-be-queried data according to the data address when the to-be-queried data does not exist, writing the to-be-queried data and the query operation information into the cache region by taking the category identifier as an index, and sending the to-be-queried data; when the instruction type is a data updating instruction, obtaining a type identifier of to-be-checked data cleared by the data updating instruction; and clearing the to-be-queried data taking the category identifier as the index in the cache region and the query operation information. The influence on the data query function can be avoided, and the maintenance efficiency and query efficiency of the stored data are improved.

Description

technical field

[0001] The present application relates to cache management technology, in particular to a cache data management method, device, storage medium and electronic equipment. Background technique

[0002] When querying or maintaining stored data, it usually occurs that multiple maintenance parties query or maintain the same set of data respectively. The query will not change the stored data, but when the stored data is maintained, or the maintenance authority between the maintainer and the stored data is modified, the stored data needs to be updated.

[0003] In the prior art, the buffer area for storing data is usually based on a hash (Hash) structure. Once the stored data needs to be updated, all the data in the buffer area will be cleared in order to ensure the consistency of the associated data. However, in practical applications, the maintenance and update of stored data may be very frequent. When multiple maintainers frequently maintain and update stored dat...
