Scalable XML Query Processing using Parallel Pushdown Transducers

  title={Scalable XML Query Processing using Parallel Pushdown Transducers},
  author={Peter Ogden and David B. Thomas and Peter R. Pietzuch},
In online social networking, network monitoring and financial applications, there is a need to query high rate streams of XML data, but methods for executing individual XPath queries on streaming XML data have not kept pace with multicore CPUs. For data-parallel processing, a single XML stream is typically split into well-formed fragments, which are then processed independently. Such an approach, however, introduces a sequential bottleneck and suffers from low cache locality, limiting its… CONTINUE READING
