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.

Browsing a dataset’s columns

Open a dataset from the lake or from a run and the context panel lists its Columns with their types. Click a column to see its lineage. This works for any dataset with a schema, including BigQuery, Postgres, and Snowflake tables.
