The document contains performance information for a data warehouse
environment. An application scenarion from the telecommunication
industry was used for the performance characterization. All references
to the customer have been removed. The information can be used to
position Red Brick in a data warehouse environment in terms of load and
query performance in a high-end environment. Configuration guidelines
addressing performance and availability are also provided.
The paper is for "Internal Use Only". We are only allowed to distribute
the paper within Digital and Red Brick.
