Since a couple of years, the NoSQL movement has developed a variety of open-source document stores. Most of them focus on high availability, horizontal scalability, and are designed to run on commodity hardware. These products have gained great traction in the industry to store large amounts of flexible data (mostly JSON). In the meantime, XQuery has evolved to a standardized, full-fledged programming language for XML with native support for complex queries, indexes, updates, full-text search, and scripting. Moreover, JSON has recently been added as a first-level datatype into the language. As of today, it is without doubt the most robust and productive technology to process flexible data.
The aim of this talk is to showcase the benefits that can be achieved by integrating the Zorba XQuery Processor with MongoDB. We will introduce the 28msec platform that seamlessly stores, indexes, and manages flexible data entirely in XQuery. The data itself is stored in MongoDB. The platform leverages MongoDB’s indexes, sharding, and consistency guarantees to scale-out horizontally. The talk will conclude by showing a benchmark of the platform and discuss perspectives of the outlined approach.
