Innovations in real-time trade execution: database speed, latency and resilience

Vailraj, Karthickram (2025) Innovations in real-time trade execution: database speed, latency and resilience. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 673-682. ISSN 2582-8266

This comprehensive article examines the technological foundations that enable real-time trade execution in modern financial markets, where performance is measured in microseconds and nanoseconds. The article delves into the sophisticated database architectures that support high-frequency trading environments, highlighting how memory-first designs, zero-copy data streaming, and concurrent write optimization techniques have revolutionized execution speed and market structure. It analyzes how these database innovations directly impact profitability through reduced latency and increased throughput while maintaining the strict consistency guarantees essential for financial transactions. The article extends to distributed replication technologies that enable synchronized order books across geographically dispersed trading venues, creating new capabilities for cross-market strategies. The article further examines emerging technologies including quantum computing applications, photonic interconnects, and computational storage that represent the next frontier in trading infrastructure. Throughout, the article emphasizes the symbiotic relationship between database technology innovation and market evolution, where technological capabilities continuously reshape trading strategies and market structures.
