Welcome to the Big Data space in the Pentaho Community wiki. This space is the community home and collection point for all things Big Data within the Pentaho ecosystem. It is the place to find documentation, how-to's, best practices, use-cases and other information about employing Pentaho technology as part of your overall Big Data Strategy. It is also where you can share your own information and experiences. We look forward to your participation and contribution!

Expectations - If you are unfamiliar with open source, this article is a good place to start. The open source community thrives on participation and cooperation. There are several communication channels available where people can help you, but they are not obligated to do so. You are responsible for your own success which will require time, effort and a small amount technical ability. If you prefer to have a relationship with a known vendor who will answer questions over the phone, help you during your evaluation and support you in production; please visit


Pentaho's Big Data story revolves around Pentaho Data Integration AKA Kettle. Kettle is a powerful Extraction, Transformation and Loading (ETL) engine that uses a metadata-driven approach. The kettle engine provides data services for and is embedded in many of the applications within the Pentaho BI suite.  As such, it comes in many forms and packages:

  • Spoon (Sometimes referred to as Kettle) - The Kettle desktop visual design tool used to create and edit ETL transformations and jobs.  Spoon also has perspectives for running and debugging, visualizing and generating data models that can be used by the rest of the Pentaho Suite.
  • Pentaho Hadoop Distribution (PHD) - This is the kettle engine packaged for distribution to a hadoop cluster.  The PHD allows kettle Transforms to be run as a map task, reduce task or combiner and take advantage of the power of the hadoop cluster.  This distribution will eventually become unnecessary as Kettle is modified to use the hadoop distributed cache to locate the resources it needs to execute within the cluster.
  • Pentaho Report Designer (PRD) - The Kettle Engine is embedded in the Pentaho Report Designer which enables PRD to generate reports from a Kettle transform without having to stage the data.  It also gives PRD access to all of the database connectors within Kettle including the NoSQL databases. 
  • Pentaho BI Platform - The Kettle Engine is embedded in the BI Platform which enables reports created with PRD that rely on transforms to be published to the web.
  • Pentaho Data Integration Server (DI Server) - Standalone server 

Kettle comes with a graphical, drag and drop design environment for designing and running Kettle Jobs and Transformations.

This is a closed wiki space

The only people with access are Pentaho Employees and BAD team

This is a first shot at getting an open source collaboration space for Big Data. It will eventually be open but is currently a work in progress and a place to put the use cases, demo's etc. I completely pulled the structure and initial content from my arse and am not in love with any of it. It is a round lump of clay, waiting to be molded by the brilliant minds of the Big Ass Data Team.
