Case Study: The Rohatyn Group achieves interactive, near-real-time risk analysis and reduces financial risk with Actian Vectorwise

The Rohatyn Group - Customer Case Study

The Rohatyn Group (TRG) is a New York–based hedge fund focused on emerging markets that needed fast, interactive risk analysis across highly volatile positions. Their proprietary in‑memory system supported current-state, tactical queries but could not store the historical volumes required (over 1,000× more data), and traditional relational or OLAP alternatives were either too costly or required specialized tooling.

TRG ran a proof of concept with Actian Vectorwise—flattening data into a single ~300‑column table and loading millions of rows on a low‑cost server—and achieved in‑memory‑like interactive performance on disk without indexing, preaggregation, or extensive tuning. Deployed to production, Vectorwise gave analysts historical access for better risk assessment, easy addition of stress tests without redesign, compatibility with existing SQL tools, and avoided expensive hardware or clustered architectures.
