Cache updating method and equipment

Abstract

The invention discloses a cache updating method. The method comprises the following steps of monitoring a binary binlog log file corresponding to a database in a target relational database management system; judging whether the log file has a target log file, wherein the target log file is a log file with a new content; if yes, parsing the target log file and parsing a data sheet which changes along with the change of the target log file under the condition that the target log file at least includes log writing, log deletion and log update statements; and updating a cache content according to the data sheet. The invention also discloses to cache updating equipment. When the storage data is generated, the cache updating equipment can parse the related data sheet from the log of the database, so that the cache update is carried out according to a data packet, and thus a cache update process can be maintained without the extra code.

Description

technical field [0001] The present invention relates to the technical field of mobile cache update, in particular to a cache update method and device. Background technique [0002] Caching technology can be used to solve the problem of the discrepancy between CPU speed and memory speed in server products, and can also improve the response speed to user requests. At present, the general data caching scheme is to save the data in the original database to the server, but when the data in the database changes, the corresponding data in the cache needs to be updated synchronously. [0003] The solutions adopted in the existing technology include: regularly update the cache, there will be a problem that the data update cannot be communicated to the user in time, but it is not suitable for Internet products with high real-time requirements; the background page operation data can also be used to update, there are new needs Or when the requirements change, it is necessary to write c...
