Hotspot data caching method based on Redis

The invention discloses a hotspot data caching method based on Redis. The hotspot data caching method comprises the following steps: step 1, acquiring all data query requests from a client within unit time; counting the occurrence frequency of each data query request in the period of time, and sorting all the data query requests according to the frequency from high to low; 2, taking N data query requests which are ranked first N, and querying data records corresponding to the N data query requests in a database; storing the N queried data records in a Redis cache. According to the invention, a large amount of hotspot data can be quickly stored in the Redis cache. 本发明公开了基于Redis的热点数据缓存方法，包括以下步骤：步骤一、获取单位时间内的所有来自客户端的数据查询请求；对该段时间内每个数据查询请求出现的频次进行统计，并按频次由高到低对所有的数据查询请求进行排序；步骤二、取排序前N的N个数据查询请求，在数据库中查询该N个数据查询请求对应的数据记录；查询到的N条数据记录存储至Redis缓存中。本发明其能够快速的在Redis缓存中存储大量的热点数据。
