Pipelining in query execution
Annita N. Wilschut, Peter M. G. Apers · 2002
It is shown that the use of an adjusted algorithm can improve the performance of a nested query execution containing join operations. Apart from the equijoin, the union, Cartesian product, Theta -join, and intersection operations can be implemented in a pipelining way. The difference, however, cannot be implemented in this way. The proposed algorithms are implemented in PRISMA/DB.>
