基于NoSQL系统的组合索引技术研究
Study of Multiterm Indexing Techniques Based on NoSQL System
摘要
Abstract
The purpose of distributed NoSQL systems is to provide high availability for large-scale of data,but they are short of the inher-ent support for complex queries that often required by overlying applications. The traditional solutions based on inverted lists for single terms perform are poorly in large-scale distributed settings. Hence, research the shortcoming that document database does not support multiple key when dealing with dynamic set of documents as the primary index,then propose an improved multiterm indexing technique. By storing the inverted lists of combinations of terms,a query-driven mechanism adaptively stores the popular term combinations derived the recent query history. This approach reduces the overall bandwidth consumption,only marginal overhead in terms of additional,but few required storage resources,obviously improving the NoSQL system’ s capacity and response time.关键词
