An Integration Approach for XML Query Parallelization on Multi-Thread Systems
Authors: , ,
Abstract: The key function parts of an XML query system include XML parsing, XPath and XQuery evaluation. Each part has its specific parallel opportunity and approach. And the efficiency of each part directly affects the overall effect of XML query parallelization. Therefore it is necessary to coordinate each part in a real query application to achieve the best overall parallel performance. In this paper, we propose a novel integration approach for parallelizing XML query. Our integration approach is based on the workflow of XQuery parallelization, where both parallel XML parsing and parallel XPath evaluation are seamlessly integrated. The approach can realize automatic parallelization of XML query and make full use of multi-thread computing resources for parallel processing. Experimental results indicate that our approach can effectively improve the overall performance of XML query application through parallel computing on multi-thread systems.
