在数据库系统的自动化物理设计调优方面已经做了大量的工作。现有的解决方案需要离线调用调优工具,并且依赖于DBA手动识别代表性的工作负载。在这项工作中,我们提出了一种替代方法的物理设计问题。具体来说,我们设计的算法是永远的,并不断修改当前的物理设计的查询工作量的变化作出反应。我们的技术具有低开销,并考虑到存储约束,更新语句,并创建临时物理结构的成本。
There has been considerable work on automated physical design tuning for database systems. Existing solutions require offline invocations of the tuning tool and depend on DBAs identifying representative workloads manually. In this work, we propose an alternative approach to the physical design problem. Specifically we design algorithms that are always-on and continuously modify the current physical design reacting to changes in the query workload. Our techniques have low overhead and take into account storage constraints, update statements, and the cost to create temporary physical structures.
