Multi-Core, Main-Memory joins: Sort vs. Hash Revisited
收藏 引用
PROCEEDINGS OF THE VLDB ENDOWMENT 2013年 第1期7卷 85-96页
作者: Balkesen, Cagri Alonso, Gustavo Teubner, Jens Oezsu, M. Tamer ETH Syst Grp Zurich Switzerland TU Dortmund Univ Dortmund Germany Univ Waterloo Waterloo ON Canada
In this paper we experimentally study the performance of main-memory, parallel, multi-core join algorithms, focusing on sort-merge and (radix-) hash join. The relative performance of these two join approaches have bee... 详细信息

FUTURE GENERATION COMPUTER SYSTEMS-THE INTERNATIONAL JOURNAL OF ESCIENCE 2009年 第5期25卷 577-585页
作者: Shao, Qihong Sun, Peng Chen, Yi Arizona State Univ Dept Comp Sci & Engn Tempe AZ 85281 USA
Existing workflow management systems assume that scientists have a well-specified workflow design before the execution. In reality, a lot of scientific discoveries are made as a result of a dynamic process, where scie... 详细信息

SELECT-PARTITIONED join - AN IMPROVED PARTITION-BASED join algorithm
收藏 引用
INFORMATION SYSTEMS 1991年 第2期16卷 199-209页
作者: HO, C JONG, SP MYUNGHWAN, K CORNELL UNIV SCH ELECT ENGN ITHACA NY 14853 USA
We propose a new partition-based join algorithm, called select-partitioned join, which performs better than the sort-merge and hash-partitioned join. The proposed select-partitioned join algorithm consists of three ma... 详细信息

HYBRID join - AN IMPROVED SORT-BASED join algorithm
收藏 引用
INFORMATION PROCESSING LETTERS 1989年 第2期32卷 51-56页
作者: CHOI, HK KIM, M Dep. Electr. Eng. Korea Adv. Inst. Sci. and Technol. P.O. Box 150 Cheongryang Seoul 130-650 Rep. Korea
This paper proposes an algorithm that improves the sort-based join method. Unlike the sort-based join, it employs both sorting and partitioning for avoiding two complete sorts of both relations, thus it will be referr... 详细信息

INFORMATION PROCESSING LETTERS 1985年 第1期21卷 11-16页
作者: NEGRI, M PELAGATTI, G Dipartimento di Elettronica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano Italy
A join operation consists of selecting from the set of all pairs of records of 2 files those pairs that possess some matching property. Because the join operation is so important in database applications, several alg... 详细信息
