Upstream Lineage: Sources

Trace the origins of data and answer "Where does this data come from?"

Lineage Investigation

Step 1: Identify the Target Type

Determine what we are tracing:

• Table
• Column
• DAG

Step 2: Find the Producing DAG

1. List DAGs: use list_active_dags and list_paused_dags
2. Read DAG source: use get_dag_source_code
3. If a run exists, use analyse_dag_latest_run to see tasks and logs
