Abstract

We present BrackitMR, a framework that executes XQuery programs over distributed data using MapReduce. The main goal is to provide flexible MapReduce-based data processing with minimal performance penalties. Based on the Brackit query engine, a generic query compilation and optimization infrastructure, our system allows for a transparent integration of multiple data sources, such as XML, JSON, and CSV files, as well as relational databases, NoSQL stores, and lower-level record APIs such as BerkeleyDB.
