2021 arXiv   pre-print
The Join operator, as one of the most expensive and commonly used operators in database systems, plays a substantial role in Database Management System (DBMS) performance.  ...  We explore the impact of the number of partitions on the performance of HHJ and propose a lower bound and a default value for the number of partitions.  ...  In Proceedings of the 1996 ACM SIGMOD International Conference on Management of Data, Montreal, Quebec, Canada, June 4-6, 1996, H.
