Data at Scale
Data at Scale is a one-day, single-track conference in Amsterdam on best practices in large-scale data processing. One day, in person, no product pitches; real engineering on real data.
Bring together database, backend, and systems engineers who actually run big workloads to share what works, what breaks at scale, and what they've learned.
Who this is for
Database, backend, and systems engineers running production data systems
Engineers and researchers working with billions of rows or terabytes-plus
Technology enthusiasts who want a serious-but-friendly day on data systems at scale
What to expect
One 45-minute opening keynote by Alexey Milovidov, original author of ClickHouse
Standard talks (around 25 minutes + Q&A) on real-world large-data work
Lightning talks (5–10 minutes) with sharp takes and fast demos
Modest exhibition and demo area for hands-on time with tools and teams
Evening reception in The Courtyard (weather permitting), running until 19:00
The schedule is intentionally single-track so everyone sees every talk.
Speakers
Talks are selected from an open CFP, with the keynote by Alexey Milovidov. The full lineup will be announced in late June. https://sessionize.com/data-at-scale-amsterdam/
Submit a talk
The CFP is open until 20 June 2026. We're looking for talks based on real-world analysis of large datasets, where the engineer who did the work shares what they measured, what broke, what they fixed, what they learned. Vendors and competitors welcome on the same terms as everyone else.
