Double-cache method, device and equipment based on asynchronous decorator and storage medium

Abstract

The invention relates to the field of cloud technology, and discloses a double-cache method, device and equipment based on an asynchronous decorator and a storage medium, which are used for extractingcache data through the asynchronous decorator and improving the cache efficiency. The method comprises the steps of: acquiring a data extraction instruction, and generating a target task layer asynchronous decorator according to the data extraction instruction; obtaining a first target data key-value pair according to the target task layer asynchronous decorator and a preset construction rule; obtaining first target data in a first cache space through the target task layer asynchronous decorator, and judging whether the first target data is a null value or not through the target task layer asynchronous decorator; obtaining second target data in a second cache space if the first target data is the null value, and judging whether the second target data is a null value or not; and obtainingtarget data from the database according to a second target data key-value pair if the second target data is the null value, and sending the target data to a preset terminal.

Description

technical field [0001] The present invention relates to the field of cloud technology, in particular to a double buffering method, device, equipment and storage medium based on asynchronous decorators. Background technique [0002] With the development of technology, caching has become a technique widely used in computers to improve performance. In the context of web applications, caching is used to persist pages or data between HTTP requests and use them multiple times without having to create new ones. Its purpose: to save application processing time and resources. [0003] Tornado is the open source version of the Web server and its common tools. Tornado is significantly different from the current mainstream Web server framework. Tornado is a non-blocking server, and the speed is quite fast. Based on Tornado's asynchronous function, Tornado can process thousands of files per second. connections, so Tornado is an ideal framework for real-time Web services. [0004] Howe...
