Abstract

The invention provides a cache updating method and device. The method comprises the following steps of: S1, receiving an access request sent by a client, wherein the access request comprises a to-be-accessed data identifier and corresponding data table identification information; S2, searching a data result corresponding to the to-be-accessed data identifier and version information of the data result from a local data cache, and searching version information corresponding to the data table identification information from a local version cache; and S3, judging whether the version information searched from the local data cache is consistent with the version information searched from the local version cache or not, and determining an updating manner of the local data cache according to the judging result. Through the cache updating method and device, the automatic updating the local cache data is realized through the trigger of the user access request, so that the local cache data is consistent with the data in a server database.

Description

technical field [0001] The present invention relates to data cache technology, and more specifically, to a cache update method and device. Background technique [0002] At present, cache (caching refers to a key-value data storage scheme stored in memory, such as MEMCACHE or REDIS, etc.) is widely used in WEB applications. In order to provide a stable and efficient user experience, many high-traffic WEB applications will consider storing data in local caches. This method is much faster than reading data directly from the background server database, so that fewer servers can be used to support higher traffic. [0003] As the data in the background server database is continuously updated, the data in the local cache also needs to be updated. Currently, the usual update method is to manually update the local cache according to the update cycle. [0004] The method of updating the local cache according to the update cycle is not targeted for the data that users need to access,...
