分布式环境下的频繁数据缓存策略
FREQUENT DATA CACHING STRATEGIES IN DISTRIBUTED ENVIRONMENT
摘要
Abstract
Using distributed caching technology can provide high performance and high availability data query in large data environment.The frequent data caching strategies for lightweight applications have the advantages of high efficiency and easy extension.Especially, it is beneficial to improve the query optimization for lightweight distributed database system.Therefore, this research studies the data caching strategies for the recent frequent query data by analyzing the characteristics of user behavior and user query.It can predict the high hit rate of the cache data and improve the efficiency of data query.Firstly, the definition of the frequency of the query was analyzed and given.Secondly, we refined the operation of the user''s query according to the influence of the time factor for the cache data.And we dealt with the different cache hits in query process through the data query frequency.Then, we integrated the cached data between nodes.Finally, the experimental results showed that the data caching strategy has a high data hit rate.It also can improve the efficiency of data query.According to the actual needs, the implementation can use different combination of cache attributes, and possesses a good scalability.关键词
