DBS3: a parallel database system for shared store
B. Bergsten, Michel Couprie, Mauricio López · 2002
The status of the DBS3 prototype, a parallel relational database system implemented on a shared everything architecture, is described. The following original aspects of its design are examined. First, DBS3 has a compilation approach (compiled C code) which allows a fine grain control of the execution. Second, DBS3 optimizes and parallelizes queries in self-scheduled parallel programs supporting interoperator and intraoperator parallelism, as well as pipeline parallelism. Third, the underlying execution model is based on a distributed store model, allowing an efficient mapping of the produced code onto several classes of parallel architectures: DBS3 on shared everything, EDBS on shared nothing.>
