Paperback. Condition: New. Print on Demand. This book addresses query processing in a database machine consisting of 11 nodes connected by high-bandwidth networks, theorizing that symmetric parallel architecture is ideal for high-speed relational query processing. Each node comprises a processor, random access memory, and a slower but much larger memory. To approach optimal speedup on this hardware architecture, relations are partitioned roughly evenly among the processors. The author explores optimizing multi-join queries under this data distribution strategy, where optimization entails minimizing the number of times relations are redistributed during a query. They find that this optimization problem, while NP-complete for general queries, is linear for a subclass of tree queries. This book will intrigue database engineers seeking to accelerate relational query processing, and computer scientists engaged in database theory and algorithm design.
