Xadoop is the attempt to place XQuery as an alternative language for Hadoop next to PigLatin, Hive etc. In contrast to the other languages, XQuery offers the advantage of being a functional standardized language for semi-structured data. The main research challenge is the automatic parallelization of XQuery code (including scripting), as well as the transfer of data between the different tasks and index management.

There exists already an non-insignificant interest in the project from banks and a startup working in the area of Hadooop. We are currently using EC2 to test our infrastructure for larger deployments and are planning to release a first demo-release soon.
