Abstract

The invention discloses a method and device for optimizing a distributed cache, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: when a first-level cache reaches the maximum data volume or the current time reaches the cleaning time of the first-level cache, storing part of cache data in the first-level cache into a second-level cache; and modifying the value of the partial cache data in the first-level cache into a key value of the partial cache data in the second-level cache. According to the embodiment, the technical problem of performance reduction caused by a cache degradation strategy under the requirements of large data volume and long time efficiency can be solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for optimizing distributed cache. Background technique [0002] The purpose of caching is mainly in the following two aspects: [0003] 1) Improve performance: a) In most cases, the select statement in SQL is where the biggest performance problem occurs. On the one hand, the select statement has many rich semantics such as join, group, order, like, etc., and these semantics are very performance-consuming; on the other hand, most applications read more and write less, so slow queries are exacerbated b) Remote calls in distributed systems will also reduce system performance, because there is network overhead, which will lead to prolonged overall response time. In order to save such performance overhead, it is very necessary to use cache when the business permits (not requiring too real-time data). [0004] 2) Relieve database pressure: When user req...
