SUCCESS STORY VectorWise at Rohatyn Group The Rohatyn Group (TRG) is a hedge fund headquartered in New York focusing on emerging markets. THE CHALLENGE Information about positions, pricing and risk is critical to investment decision making. For tactical decision making TRG provided analysts immediate access to the information they need inCustomer a format that they can use through a self-service data access environment. TRG maintain extensiveRohatyn Group data about the current state of all their market positions in a multi-dimensional data structure managed by a proprietary in-memory database. This enabled analysts to interactively answer theirIndustry questions about the current state of their investments.Financial Services The combination of market volatility and a desire to do more strategic analysis drove the needChallenge to understand how the positions had performed over time. While the existing solution provided• Risk management the interactive analysis TRG were looking for, it did not have the historical data. They wanted the required in the highly user tools to remain the same and the query responses to be interactive, but they needed to do the volatile market of analysis on more than 1000 times the data. hedge funds.Solution ALTERNATIVESVectorWise was deployed to The proprietary in-memory database clearly would not be able to hold the volume of data requiredprocess data from multiple to analyze market positions over time, so TRG started to look for alternatives.systems so that hedge fundmanagers could evaluate their Existing relational database technology was ruled out because solutions could not provide thepositions in near real time. interactivity the analysts wanted without spending a fortune on hardware, database tuning, or both.Benefits A third option TRG evaluated was the use of a specialized OLAP engine. While the engine wouldAbility to mitigate financial risk probably be able to provide the interactivity the analysts wanted, the implementation would require specialized OLAP skills and the existing ad hoc data access tools would not be able to interact directly with the OLAP environment. SOLUTION TRG learned about VectorWise during its Technology Preview Program in the Spring of 2010. Warren Master, CTO of TRG, read about the underlying technology and decided to give VectorWise a try. The result: incredibly fast performance out of the box. Warren’s first experience made him decide to run a full proof of concept on a low-cost server: a $999 server with only 2 CPU cores and 2 GB of memory! For the VectorWise POC TRG could have mapped the existing data structures to a star schema with 20 dimensional tables and a fact table. Instead TRG decided to flatten all of the data into a single table with almost 300 columns. They loaded millions of rows of historical data into
