ClickHouse

Next week, we will be hosting the flagship ClickHouse Conference in the Amsterdam Zoo! Register to see the latest advancements in the database area and to meet with ClickHouse engineers on October 28th.

Speed is no longer technical, it’s structural. ⚡️ Only 11 days left until Big Data & AI World Spain , where more than 400 companies and industry leaders will share how data and AI are redefining business performance. In an AI-driven world, traditional databases simply can’t keep up. AI demands faster ingestion, sub-second queries, and massive scalability at an affordable cost. That’s why the world’s leading AI companies; Anthropic, Meta, LangChain, Vercel, Cursor, and Sierra; rely on ClickHouse as the foundation of their infrastructure. Its open-source, column-oriented engine for real-time OLAP analytics can process hundreds of millions of rows per second per server, enabling instant decisions on massive datasets. In today’s #AIeconomy, infrastructure has become the new competitive edge. At the Data & AI Theatre of Big Data & AI World Spain, Gonçalo Pina (GTM Lead, SEMEA – ClickHouse) and Miguel Garcia Lorenzo (VP of Engineering – Factorial) will lead the session “When Speed Matters: ClickHouse, the World’s Fastest Analytical Database Powering Factorial’s AI-Driven Analytics.” They’ll show how ClickHouse Cloud enables lightning-fast decision-making, and how Factorial leverages it to drive its analytics strategy built on speed, simplicity, and efficiency. 💡 In the era of AI, speed isn’t a technical luxury, it’s the foundation of strategy. #BigDataAIWorld #TechShowMadrid #ClickHouse #Factorial #RealTimeAnalytics #DataPerformance #AI #GenAI #BigData #DataInfrastructure #Madrid

💙 So grateful to see stories like this from our community! Nemanja L. at profiq wrote a really thoughtful piece about his team's ClickHouse certification journey. What we love most is how he frames certification as more than just a credential - it's about building genuine problem-solving skills and creating trust with customers. The fact that Nemanja took the time to share detailed exam tips and learning strategies? That's the kind of community spirit that makes our ecosystem stronger. Key takeaways from his certification journey: ✅ Complete ALL the labs in the 10-module training ✅ Practice with real datasets using certification objectives as your guide ✅ Master complex SQL queries, CTEs, and JOINs ✅ Learn to navigate the docs efficiently during the 2-hour exam Appreciate when community members take the time to share their learning journey and practical advice like this. Thank you, Nemanja, for being part of what makes the ClickHouse community special! 🙏 https://lnkd.in/ekWdfmMh

Throwback: Feature stores - What are they good for? Quite a lot, actually! ⚡ Looking back at our blog post that broke down: 🔸The basics of feature stores 🔸Why you might (or might not) need one 🔸How ClickHouse could simplify your ML data architecture Plus we announced our integration with Featureform back then. Still relevant today - give it a read! https://lnkd.in/dMebxyvH

Can lakehouses and open table formats handle the real time telemetry of observability? Open table formats like Apache Iceberg and Delta Lake on object storage are reshaping how we think about warehousing and analytics, but are they ready for the demands of observability? In this post, we take a look at: • 🌊 Where Iceberg, Delta, and Parquet shine for o11y • ⚙️ Where they fall short for logs, traces, and metrics • 💡 How innovations like Parquet VARIANT, clustering, and new file formats are changing the game and pointing to a bright future The answer: its a little complicated but looking promising 🤞

I always wondered who’s faster. Superman or Flash? And for the first time, I had my answer. Last week at AWS Cloud Days, I met the ClickHouse team. They weren’t talking about capes or costumes. They were talking about speed, real speed. ClickHouse is built for people who move fast. For observability. For ML and GenAI. For business intelligence, financial services, fraud, and cybersecurity. It’s the kind of database that doesn’t just process queries. It finishes them before you blink. What impressed me most was how seamlessly it runs on Amazon Web Services (AWS) Cloud. No heavy lifting. No complex setup. Just instant scale and performance that actually feels superhuman. Because in the AI era, the real heroes aren’t the ones who fly. They’re the ones who deliver answers in milliseconds. 👏 Credit to the team Christoph Wurm, Arno van Driel Tyler Hannan for showing what true speed looks like, and how it powers the next wave of intelligent systems. #TechWithGokul #AWSCloud #ClickHouse #DataEngineering

Logs ici. Métriques là. Traces ailleurs. Votre observabilité est éparpillée et vous comparez encore les dashboards vous-même ? Je présenterai un webinar exclusif le 29 octobre 2025 pour montrer comment ClickStack (ClickHouse + HyperDX + OpenTelemetry) unifie logs, métriques et traces dans une seule plateforme open source. 🎥 Webinar Zoom 🔗 Inscrivez-vous ici : https://lnkd.in/e6d_Bd6h . . . . . #Observability #ClickHouse #ClickStack #OpenTelemetry #HyperDX #DataEngineering #DevOps #SRE #Logs #Metrics #Traces #Cloud #OpenSource #Innovation
