Apache VXQuer will be a standards compliant XML Query processor implemented in Java. The focus is on the evaluation of queries on large amounts of XML data. Specifically the goal is to evaluate queries on large collections of relatively small XML documents. To achieve this queries will be evaluated on a cluster of shared nothing machines. However there are no XQuery processors available today that are capable of processing these datasets in parallel and making the contained information accessible.

VXQuery - Query XML Data

Bagri is a Document Database built on top of distributed cache solution like Hazelcast or Coherence. The system allows to process semi-structured schema-less documents and perform distributed queries on them in real-time. It scales horizontally very well with use of data sharding, when all documents are distributed evenly between distributed cache partitions.

Started as a Native XML DB initially, the system has grown to process any kind of documents with self-describing data format (JSON, for instance) via pluggable parsers API. As a schema-free solution Bagri does not require any meta-data change when processing document formats evolve. An internal XQuery engine used for data querying and transformation provides exceeding flexibility in data processing tasks based on solid foundation of XQuery standards. The XQuery language is still evolving rapidly in answer to market demands which makes it the best candidate for all-in-one tool for processing of any volumes of semi-structured data.
