SP2Bench:一个SPARQL性能基准

SP2Bench: A SPARQL Performance Benchmark

Michael Schmidt, Thomas Hornung, Georg Lausen, Christoph Pinkel

摘要:

最近,用于RDF的SPARQL查询语言已经达到了W3C推荐标准。为了响应这个新兴的标准,数据库社区目前正在探索RDF数据的有效存储技术和SPARQL查询的评估策略。要对这些方法进行有意义的分析和比较,就必须有一个全面和普遍的基准平台。为此,我们开发了SP^2Bench,这是一个公开可用的、特定于语言的SPARQL性能基准。SP^2Bench是DBLP场景中的解决方案,它包括一个用于创建任意大的类DBLP文档的数据生成器和一组精心设计的基准查询。生成的文档反映了原始DBLP数据集中遇到的关键特征和社交世界分布,而查询则在此数据之上实现了有意义的请求,涵盖了各种SPARQL操作符星座和RDF访问模式。作为概念验证,我们将SP^2Bench应用于现有引擎,并讨论其优势和劣势,这些优势和劣势直接来自基准测试结果。

英文摘要:

Recently, the SPARQL query language for RDF has reached the W3C recommendation status. In response to this emerging standard, the database community is currently exploring efficient storage techniques for RDF data and evaluation strategies for SPARQL queries. A meaningful analysis and comparison of these approaches necessitates a comprehensive and universal benchmark platform. To this end, we have developed SP^2Bench, a publicly available, language-specific SPARQL performance benchmark. SP^2Bench is settled in the DBLP scenario and comprises both a data generator for creating arbitrarily large DBLP-like documents and a set of carefully designed benchmark queries. The generated documents mirror key characteristics and social-world distributions encountered in the original DBLP data set, while the queries implement meaningful requests on top of this data, covering a variety of SPARQL operator constellations and RDF access patterns. As a proof of concept, we apply SP^2Bench to existing engines and discuss their strengths and weaknesses that follow immediately from the benchmark results.
