Bordawekar等人在2009年提出了一种实用且有前途的并行XML查询的方法，该方法可以在现有的XML数据库引擎上实现并行化。虽然他们通过实验证明了这种方法的加速效果，但他们的实践已经过时了，因为软件环境已经随着XQuery处理能力的变化而发生了很大的变化。在这项工作中，我们实现了他们的方法在两种方式上的最先进的XML数据库引擎和实验证明，我们的实现可以带来显着的商品服务器上的加速。
A practical and promising approach to parallelizing XPath queries was proposed by Bordawekar et al. in 2009, which enables parallelization on top of existing XML database engines. Although they experimentally demonstrated the speedup by their approach, their practice has already been out of date because the software environment has largely changed with the capability of XQuery processing. In this work, we implement their approach in two ways on top of a state-of-the-art XML database engine and experimentally demonstrate that our implementations can bring significant speedup on a commodity server.
