摘要

在Internet上交换的大部分数据将很快用XML编码,从而允许复杂的过滤和基于内容的路由。我们已经构建了一个名为YFilter的过滤引擎,它根据同时涉及路径表达式和谓词的XQuery或XPath查询过滤流XML文档。与之前的工作不同,YFilter使用了一种新颖的基于nfa的执行模型。我们介绍了YFilter的结构和算法,并展示了它在各种工作负载下的效率和可扩展性。

YFilter: efficient and scalable filtering of XML documents
Much of the data exchanged over the Internet will soon be encoded in XML, allowing for sophisticated filtering and content-based routing. We have built a filtering engine called YFilter, which filters streaming XML documents according to XQuery or XPath queries that involve both path expressions and predicates. Unlike previous work, YFilter uses a novel NFA-based execution model. We present the structures and algorithms underlying YFilter, and show its efficiency and scalability under various workloads.
