Add to ORKGIn this paper, we investigate two scheduling approaches for multicomputer-based parallel database systems: The competition.based technique allows queries to compete freely for computing resources, while the planning-based scheme relies on a centralized scheduler to plan the execution of all queries. Our studies show that competition-based though provides impressive performance, the planning-based is consistently the better approach
