Embodiment Construction

[0023] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0024] In order to reduce the network communication time consumption in the stage of reading and writing cached data, achieve faster data reading and writing operations, and avoid developers from judging whether the cache hits or not, this solution designs the distributed cache module as a dynamic link library. In this way, the business process and the distributed cache are compiled into the same process, so that the business can realize the read and write operations of the cache only by reading and writing the local memory, and realize the judgment of whether the data to be accessed is hit in the cache, thereby improving the read and write efficiency and development efficiency.

Abstract

The invention discloses a distributed cache implementation method. Each distributed cache is independently compiled into a dynamic link library and set into different application servers. The implementation method comprises the steps of compiling the upper layer service in the application service and a cache library provided in a dynamic link library way in the server into a same process; performing reading / writing / deleting operations by the upper layer service through calling the dynamic link library compiled in the same process; in the reading operation, enabling the dynamic link library which is in the same process with the upper layer service to receive reading parameters sent from the upper layer service, reading the corresponding data from the cache library or a relational database according to the reading parameters, and submitting the data to the upper layer service; and in the writing operation, enabling the dynamic link library which is in the same process with the upper layer service to receive writing parameters sent from the upper layer service, and writing the corresponding data into the cache library or the relational according to the writing parameters. By adoption of the application, the cache reading and writing efficiency can be improved.

Description

technical field [0001] The present application relates to computer technology, in particular to a method for implementing a distributed cache. Background technique [0002] With the popularization and development of the Internet, the application server needs to cope with the rapidly increasing number of user requests. In order to reduce the pressure on the database server and improve the response speed of the business to user requests, it is necessary to cache the data frequently used by users, that is, temporarily store user data It exists in memory, and its direct purpose is to improve the response speed of data. The working ideas of the existing distributed cache system represented by memcached and redis are as follows: figure 1 As shown, the distributed cache is located on an independent machine node. When the business process accesses data, for the read operation, it first needs to access the distributed cache through the network IO. If the data to be accessed is in th...
