摘要：
the index selection problem (isp) is one of the central issues in database tuning. given a workload, a dataset, a set of index candidates, and some constraints on indexes to be built (e.g., maximum storage budget or maximum index number), isp aims to select a subset of index candidates to maximise the performance of the workload while meeting the constraints. proposed solutions for isp range from sophisticated multi-step algorithms to approaches that adopt the learning methods. in this talk, we divide these methods into two categories, traditional methods, and learning-based methods. we revisit three typical traditional methods and four recent learning-based solutions.
