Fine-grained Non-blocking Join Algorithm Based on XJoin
基于XJoin的细粒度无阻塞连接算法

Wide-area distribution raises significant performance problems for traditional query processing techniques as data access becomes less predictable due to link congestion,load imbalances,and temporary outages.Non-blocking joi-ning query execution is a promising approach to coping with unpredictability in unreliable network and hiding intermi-ttent delays in data arrival by reactively scheduling background processing.Classical non-blocking two-way joining technique such as XJoin fail to deliver acceptable per...
