Infobright, a open source data warehousing start up addresses the performance issues that usually come along with a data warehouse by implementing a highly compressed column-oriented store. The data is stored in columns instead of rows. This allows for reduced I/O because of the compression ratios obtained on the columns. Data is stored as 65K blocks or nodes containing a meta data store about the relationships between columns.
Some of the key customers of Infobright are RBC Royal Bank and Xerox. They claim their product would be ideal for data warehouses ranging from 500GB to 30TB. Their compression ratios are close to 40:1 according to their community blogs. The most attractive feature about them was the compatibility with the existing Business Intelligence tools like Business Objects and Pentaho.
I wasn't very convinced with the concurrency offered by them. It supports 50-100 users with 5-10 concurrent queries. I will watch for the progress of this new exciting player in the already crowded BI market.
