Click-a-thon 2026: Build with the fastest database on the planet
🚀 ClickHouse's first in-person developer hackathon in India is here.

If you've ever wanted to push the limits of real-time analytics, ship something ambitious with a small team, and get your work in front of the wider data community, this is the room to be in.
