Embodiment Construction

[0026] This application is applied to large-scale web applications (such as portal websites) with high concurrency. This application adopts the strategy of separating read and write, and asynchronously pre-writes the cache content within a period of time before the cache expires, thereby ensuring the high availability and high hit rate of the cache; at the same time, reducing the impact of write operations on the cache layer Pressure to protect the security of back-end data sources.

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] According to an embodiment of the present application, a cache management method for a cache server is provided.

Abstract

The invention discloses a buffer management method and buffer management system for a buffer server. The buffer management method comprises the steps of writing data of buffer items into a buffer, calculating a timestamp of a next pre-refreshing time of the data of the buffer items according to the set failure time and lead time of the data of the buffer items, pushing the data of the buffer items to a message queue, and carrying out asynchronous buffering and refreshing operation on the data of the buffer items in the message queue according the timestamp of the next pre-refreshing time of the data of the buffer items. By means of the buffer management method and buffer management system for the buffer server, the safety of a rear end data source can be effectively protected.

Description

technical field [0001] The present application relates to the communication field, and in particular to a cache management method and a cache management system for a cache server. Background technique [0002] At present, the Internet has developed into a global network that is used in various industries and transmits massive multimedia and dynamic information. People can not only read dynamically generated information through the Internet, but also use highly interactive services such as e-commerce, instant messaging, and online games. [0003] With the ever-expanding scale of the Internet and the growing user base, new requirements are put forward for the construction of Internet websites. For the portal website, the first problem to be solved is the problem of speed. When the data reaches more than one million levels, and it is frequently visited by millions of users, the response speed of the system will be very slow. [0004] Caching technology is a key technology to ...
