Rocky: Rust SQL engine with branches, replay, and column lineage
Summary
Rocky is a Rust-based control plane for warehouse pipelines featuring branches, replay, and column-level lineage with compile-time safety and per-model cost attribution. The project demonstrates AI-assisted model generation loops and compile-time data contracts, plus POCs for schema drift detection and column-level lineage, aimed at maintaining data quality while enabling branch experiments in environments like Databricks or Snowflake.
