Case Study: Tokyo Stock Exchange achieves millisecond performance analysis with Splunk

Tokyo Stock Exchange processes 80,000 transactions per second with Splunk

The Tokyo Stock Exchange (TSE) needed to ensure world-class reliability for its high-speed "arrowhead" trading system but faced challenges with inefficient, manual data analysis that took days to complete. The exchange lacked real-time visibility into its transactions. To address this, TSE turned to the vendor Splunk and implemented the Splunk platform for data analytics.

Splunk provided a solution that automated data analysis, giving TSE millisecond-level visibility into system performance and the ability to monitor 80,000 transactions per second. The results were significantly faster analysis, tens of times quicker than the previous method, leading to improved operational efficiency and cost-effectiveness. By using Splunk, TSE gained a complete, real-time picture of its system health, enabling proactive problem resolution and measurable return on investment.
