| description | Generate column-level lineage for a specific task |
Generates column-level lineage for a specific transform task, showing how each output column traces back to its source columns through SQL transformations. This provides fine-grained data provenance information.

--task <value>: Task name in the form domain.task (required)--output <value>: Output JSON file path (default: console output)--accessToken <value>: Access token for authentication (e.g. GCP)--reportFormat <value>: Report output format: console, json, or htmlAnalyzes the SQL query for a task and traces each output column back to its source columns. For example, given:
-- metadata/transform/kpi/revenue_summary.sql
SELECT
o.order_id,
o.timestamp AS order_date,
SUM(ol.quantity * ol.sale_price) AS total_revenue
FROM
starbake.orders o
JOIN starbake.order_lines ol ON o.order_id = ol.order_id
GROUP BY
o.order_id, o.timestamp
The column lineage output would show:
order_id ← starbake.orders.order_idorder_date ← starbake.orders.timestamptotal_revenue ← starbake.order_lines.quantity, starbake.order_lines.sale_pricestarlake col-lineage --task kpi.revenue_summary
