Problems solved by technology

[0005] 3. High volume of visits: The reading service system needs to provide query services for a large number of systems, terminals or applications. Therefore, the reading service system has a very high number of visits; in addition, the reading service is an underlying service, and the performance requires a response time within 5ms;
[0010] 2. As the storage scale of the Redis cluster used by the read service system becomes larger and larger, its maintenance becomes more and more difficult

Abstract

The invention discloses a data storage method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps of: counting a queried frequency of target data in a three-level cache of a cache system, and taking the target data of which the queried frequency exceeds a preset value as hot data; And storing the hot data into a secondary cache of a cache system. According to the embodiment, the maintenance difficulty of the cache system of the reading service system is reduced; Query efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for storing data. Background technique [0002] The read service system is a data cache system that can provide data query services for other systems, terminals or applications. The read service system has the following characteristics: [0003] 1. Large amount of data: Usually, the reading service system needs to provide billions of data query services, and these data require PB-level storage space; [0004] 2. Rapid growth of data volume: With the continuous development of the business of the reading service system, the growth rate of data volume is fast; [0005] 3. High volume of visits: The reading service system needs to provide query services for a large number of systems, terminals or applications, so the reading service system has a very high number of visits; in addition, the reading service is an underlying service, and the performance re...
