Column-Level Lineage

Column-level lineage in Coalesce Transform shows how output columns depend on upstream columns inside your pipeline. It helps you assess blast radius when renaming sources or changing transformations.

Transform derives column lineage from Node SQL, Node Type templates, and supported patterns in Node Type V2 annotations. Complex SQL such as nested CTEs may lineage partially until patterns are supported.

Column-level lineage inside Transform complements Field-level lineage in Coalesce Catalog, which spans warehouse and BI assets across integrations.

See Getting Started with Node Type V2 for annotation patterns that improve lineage capture.
