Abstract :
Many techniques for query scheduling in a parallel database system schedule a single query at a time. The scheduling of queries for parallel database systems by dividing the workload into batches is investigated. Scheduling algorithms that exploit the common operations within the queries in a batch are proposed. The performance of the proposed algorithms is studied using a simple analytical model and a detailed simulation model. It is shown that batch scheduling can provide significant savings compared to single query scheduling for a variety of system and workload parameters
