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 method and a device for storing data, and relates to the technical field of computers. A specific implementation of the method includes: counting the query frequency of the target data in the third-level cache of the cache system, and using the target data whose query frequency exceeds a preset value as hot data; storing the hot data to the second level of the cache system cache. This embodiment reduces the difficulty of maintaining the cache system of the read service system; and improves query efficiency.

Description

technical field [0001] The present invention relates to the field of computer technology, and 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 read 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 read service system, the growth of data volume is rapid; [0005] 3. High traffic volume: The read service system needs to provide query services for a large number of systems, terminals or applications, so the traffic volume of the read service system is extremely high; in addition, the read service is an underlying service, and the performance requires a r...
