不确定数据流上的并行Skyline查询算法
Parallel Skyline Computation over Uncertain Data Streams
摘要
Abstract
Skyline query processing over uncertain data streams has attracted considerable attention recently. The traditional centralized stream processing algorithms can hardly process Skyline query of massive data. On the other side, cloud computing provides great opportunities for distributed and parallel Skyline query processing with its massive computing resources and effective storage management manners. Motivated by the above facts, this paper proposes a parallel Skyline over uncertain data streams algorithm (PSUDS) by partitioning the sliding window. This algorithm is able to parallelize the Skyline processing over uncertain data streams to solve the performance problems within the traditional centralized stream processing algorithms. Massive experiments demonstrate that the proposed algorithm has good parallel scalability.关键词
