Overview
Column lineage traces how individual fields flow from source to sink — through SQL queries, dbt models, and Spark transformations. Use it to answer which upstream column does this metric come from? or if I drop this column, what breaks?
Column lineage is captured automatically when your producers emit OpenLineage with column-level facets. Most modern dbt and Spark integrations include this out of the box.
