    Finally, a semantic layer that actually works for LLMs without requiring us to rewrite our entire database schema.

    Connected this to our PostgreSQL and BigQuery instances. It translates natural language questions into highly accurate semantic queries.

    Built on DataFusion, so the query planning is incredibly fast. We paired it with a Docker-based deployment in just a few minutes.

    Does this support dynamic schema updates or do we need to restart the engine every time a table changes?
