Jev in production › SQL and data pipelines
Registers Jev's noul, choice, score and ask as async SQL functions on an Apache DataFusion SessionContext, so a query answers typed questions for every row through TypeSafe, OpenRouter or a compatible endpoint.

TypeSafe built Jev to hand software a decision instead of a paragraph: how likely something is, which option it is, or where it sits on a scale you wrote. jev-datafusion runs those decisions inside DataFusion, so you can do it at petabyte scale. That unlocks work that never fit in a single prompt. Score every open ticket. Route a year of email. Ask five questions of every meeting note and join the answers to the rest of the warehouse. A few of those queries are in Examples.
