Problems solved by technology

[0005] If there is no data to be accessed in the database itself, it will cause cache penetration problems;
[0006] The cache is occupied too much, causing waste;
[0007] Reading and querying data only based on the hash value will cause misjudgment

Abstract

The invention discloses a data caching method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: determining whether a node of data to be accessed exists in a cache or not; when the nodes of the data do not exist in the cache, obtaining the data from a database, establishing the nodes of the data in the historical queueof the cache, and storing the data into the nodes; and when the node of the data exists in the cache, updating the storage position of the node of the data according to the current moment. Accordingto the embodiment, the access time efficiency of the data and the hit rate of reading the data can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, electronic equipment and computer-readable medium for caching data. Background technique [0002] The cache is the buffer for data exchange. When a piece of hardware wants to access data, it will first search for the required data from the cache. If it is found, it will be executed directly, and if it cannot be found, it will access the database. Since the running speed of the cache is faster than that of the database, the function of the cache is to improve the timeliness of data access and reduce the access pressure of the database. If there is no data to be accessed in the database, the next time the data is accessed, the cache will be bypassed and the database will continue to be accessed, resulting in cache penetration. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in ...
