N2 - Twig query processing is one of the core operations of XML queries. Centralized holistic twig algorithms suffer great efficiency losses when large-scale XML documents are partitioned and stored in the cloud. Previous work on distributed twig query processing have some limitations, e.g., utter dependence on priori knowledge of query patterns, iteration of MapReduce jobs, etc. In this paper, our arbitrary XML partitioning and storage strategy require no knowledge of query pattern; twig queries can be efficiently processed in a single-round MapReduce job with good scalability. Extensive experiments are conducted to verify the efficiency and scalability of our algorithms.
