According to a recent LinkedIn post from ClickHouse, Cloudflare is highlighted as running some of its heaviest internet analytics workloads on ClickHouse technology. The post notes that Cloudflare, which serves roughly one-fifth of the world’s websites, has reportedly relied on ClickHouse for nearly a decade.
The LinkedIn post also references a prior meetup where Cloudflare demonstrated a single query scanning 96 trillion events in under two seconds, and expanding to 1.61 quadrillion events for a full day while maintaining sub-two-second response times. The scenario further described a simulated disconnect of all North American traffic, with European clusters across more than 300 data centers absorbing the load within a similar error margin.
For investors, the post suggests that ClickHouse is deeply embedded in mission-critical analytics at a major internet infrastructure provider, supporting extremely high-volume, low-latency workloads. This kind of reference deployment may strengthen ClickHouse’s perceived technical credibility and could support customer acquisition, pricing power, and long-term demand for its analytics platform.
The mention that Cloudflare recently agreed to help OpenAI index the open web in real time, combined with its existing analytics on ClickHouse, implies potential indirect exposure to growing AI-driven traffic and data needs. If such large-scale, latency-sensitive use cases continue to expand, ClickHouse could benefit from increasing infrastructure spend on high-performance analytical databases, enhancing its competitive position in the data and analytics market.
