摘要

为了解决数据库中经典的选择性估计问题，最近在[3]中提出了一种完全不同的方法PlanBouquet，其中完全放弃了估计过程，取而代之的是校准的发现机制。这种新结构的有益结果是，首次获得了对最坏情况性能的可证明保证，从而促进了健壮的查询处理。

Platform-independent robust query processing

To address the classical selectivity estimation problem in databases, a radically different approach called PlanBouquet was recently proposed in [3], wherein the estimation process is completely abandoned and replaced with a calibrated discovery mechanism. The beneficial outcome of this new construction is that, for the first time, provable guarantees are obtained on worst-case performance, thereby facilitating robust query processing.
