Key Challenge

Customer Challenge

The customer had vast amounts of big financial data stored in a large kdb+ data warehouse. Although the existing warehouse was optimally designed, they still needed a rolling subset of data to be immediately available at all times.

From large historical reference data tables to high-frequency real-time pricing data, users wanted instant access. Providing big data fast is what kdb+ is built for – but we needed to take it a step further to give an edge to their algo trading and quant analysis.


Power of kdb+

Version1’s kdb+ specialists coupled the power of kdb+ with high-performing hardware to build a customized central caching solution. Working with the customer’s requirements of speed and scalability, a bespoke gateway layer contained in-memory mappings to trade and reference data.

This was implemented across all asset classes, from municipal bonds to FX – eliminating latency problems. Given the volatility of such a system, robust failover safeguards ensured the system ran smoothly for its thousands of daily users.

Real Differences...


As a result of this engagement, the following benefits were delivered to the customer:

  • A customized central caching system which significantly speeds up data retrieval
  • Readily scalable solution that can be dynamically applied to address any platform’s needs
  • More reactive and efficient algo trading applications
