Pentaho Corp continues to update its open source business intelligence platform; this time released a new version of its Mondrian online analytical processing (OLAP) module.
Mondrian 2.3 comes with advanced caching techniques for enhanced scalability. Pentaho officials claim the tool is now suitable for active (i.e. low latency) data warehouse environments that run mixed workloads.
Pentaho has also added new query trap and abort capabilities that guard against runaway queries grinding BI performance to a halt.
The new Mondrian software also comes with expanded support for additional open source databases like Ingres and LucidDB. The latter is part of the Eigenbase project.
Pentaho has also updated Mondrian’s Cube Designer component to speed up the creation of OLAP (multidimensional) schemas, including snowflake variants.
Mondrian, which was set up in 2001, was acquired by Orlando, Florida-based Pentaho in November 2005 and has been integrated into the Pentaho BI Suite as Analysis Services. The company has been aggressively upgrading the software since, adding more administration and richer end-user features including a graphical cube designer and optimized SQL querying.
Subscription-based support and indemnification for Mondrian is available from Pentaho. The 2.3 and Cube Designer 0.7.2 modules can be downloaded from the company’s website.
Pentaho was founded in 2002 by former executives of leading commercial software firms like IBM, Hyperion Solutions, Cognos, Oracle and SAS. The company is effectively stewarding the development of a LAMP-like BI stack that pulls together a set of interoperable open source BI tools into a comprehensive integrated BI stack.
Pentaho also owns other open source projects like JFreeReport (enterprise reporting), Kettle (ETL), and Weka (data mining) that integrate to form the backbone of its BI Suite.
