On applying hash filters to improving the execution of multi-join queries
收藏 引用
VLDB Journal 1997年 第2期6卷 121-131页
作者: Chen, Ming-Syan Hsiao, Hui-I Yu, Philip S. Electrical Engineering Department National Taiwan University Taipei Taiwan IBM T.J. Watson Research Center Yorktown NY 10598 P.O.Box 704 United States
In this paper, we explore an approach of inter-leaving a bushy execution tree with hash filters to improve the execution of multi-join queries. Similar to semi-joins in distributed query processing, hash filters can b... 详细信息
