Effective and Robust Pruning for Top-Down Join Enumeration Algorithms

Finding the optimal execution order of join operations is a crucial task of today's cost-based query optimizers. There are two approaches to identify the best plan: bottom-up and top-down join enumeration. For both optimization strategies efficient algorithms have been published. However, only...
