摘要

在数据管理上下文中,健壮性通常与针对故障、恢复、冗余、灾难准备等的弹性相关。另一方面,健壮的查询处理是关于性能和可伸缩性的健壮性。它不仅仅是进度报告或可预测性。一个可预测的失败或明显表现不佳的系统可能比一个不可预测的系统要好,但它不是健壮的。

Robust query processing
In the context of data management, robustness is usually associated with resilience against failure, recovery, redundancy, disaster preparedness, etc. Robust query processing, on the other hand, is about robustness of performance and of scalability. It is more than progress reporting or predictability. A system that fails predictably or obviously performs poorly may be better than an unpredictable one, but it is not robust.
