分布式数据库事务分类策略研究
Study of Transaction Classification Strategy in Distributed Database
摘要
Abstract
In view of the problem that the distributed database system needs to specify the execution site for transactions in advance,this paper proposes a transaction classification deployment strategy of distributed database by analyzing the distributed database query cost model.The similar transactions which are clustered by hierarchical clustering algorithm are deployed to the same site.Query matrix and similarity matrix are constructed for query transaction in the clustering process.Experimental results show that under the conditions that each slice has the same redundancy,test table data are more than 1 million and the number of concurrent people is 100,the distributed database system based on this strategy has shorter concurrent query time and faster system response rate than centralized database system.关键词
