对数据仓库进行基准测试

Benchmarking data warehouses

Jérôme Darmont, Fadila Bentayeb, Omar Boussaïd

摘要:

数据仓库体系结构的选择和优化技术对决策支持查询性能至关重要。为了方便这些选择,必须评估所设计的数据仓库的性能,通常使用基准。这些工具既可以帮助系统用户比较不同系统的性能,也可以帮助系统工程师测试各种设计选择的效果。虽然事务处理性能委员会的标准基准解决了第一个问题,但它们的可调性不足以解决第二个问题,并且无法对不同的数据仓库模式进行建模。相比之下,我们的数据仓库工程基准(DWEB)允许生成各种特定的合成数据仓库和工作负载。DWEB是作为一个Java自由软件实现的,它可以与大多数现有的关系数据库管理系统接口。DWEB的完整规格,以及我们进行的实验,以说明如何使用我们的基准测试,在本文中提供。

英文摘要:

Data warehouse architectural choices and optimization techniques are critical to decision support query performance. To facilitate these choices, the performance of the designed data warehouse must be assessed, usually with benchmarks. These tools can either help system users comparing the performances of different systems, or help system engineers testing the effect of various design choices. While the Transaction Processing Performance Council's standard benchmarks address the first point, they are not tunable enough to address the second one and fail to model different data warehouse schemas. By contrast, our Data Warehouse Engineering Benchmark (DWEB) allows generating various ad-hoc synthetic data warehouses and workloads. DWEB is implemented as a Java free software that can be interfaced with most existing relational database management systems. The full specifications of DWEB, as well as experiments we performed to illustrate how our benchmark may be used, are provided in this paper.
