On May 23rd 2012 Pentaho and 10gen are jointly announcing a partnership to provide direct integration between Pentaho Business Analytics and MongoDB.
MongoDB is a scalable, high-performance, open source NoSQL database featuring document-oriented storage, auto-sharding for horizontal scalability, rich document-based queries and fast in-place updates. MongoDB is designed with both scalability and developer agility in mind. Instead of storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with dynamic schemas. The goal of MongoDB is to bridge the gap between key-value stores (which are fast and scalable) and relational databases (which have rich functionality).
Working together, Pentaho and 10gen offer the first MongoDB-based big data analytics solution to the market. This solution combines MongoDB with Pentahos visual interfaces for high-performance data input, output and manipulation, as well as data discovery, visualization and predictive analytics. This makes it easy and productive for IT staff, developers, data scientists and business analysts to operationalize, integrate and analyze both big data and traditional data sources.
MongoDB and further BigData and NoSQL connectors are available in all editions of Kettle including Community, Basic, Professional and Enterprise since Version 4.3.
Kettle makes it really easy to extract data from multiple big data and traditional sources, and integrate it into a data mart or warehouse. The visual interfaces for big data will accelerate development and maintenance of MongoDB-based solutions a lot!
