NoDB

A high-performance, in-memory, git-backed OLAP database of nothing.

Because the best database infrastructure is no database infrastructure.

Using NoDB with DuckDB

D attach 'https://github.com/jakthom/nodb/raw/refs/heads/main/catalog' as nodb;

NoDB Roadmap

• NoDB will soon leverage Vortex to achieve high-performance random-access reads and scans of nothing.

• NoDB will soon experimentally support NoLLM, NoML, and NoAI.

• NoDB will natively integrate with NoLake.

• NoDB is currently NoGovernance but plans to support NoSecurity, an increasingly-asked-for feature.

• No DR is on the roadmap (though proprietary and only provided by our NoBYOC offering).
