annotating-task-lineage

You can add data lineage to Airflow tasks by manually annotating inlets and outlets with OpenLineage datasets or Airflow assets, enabling lineage tracking for operators without built-in extractors.

Manual lineage annotation using inlets and outlets is a method to explicitly declare data inputs and outputs for Airflow tasks, allowing teams to track data flow from sources to targets.

Yes, you can use OpenLineage datasets or Airflow assets to define inlets and outlets for a simple BashOperator, enabling downstream lineage tracking even without a dedicated extractor.

You need to manually specify inlets and outlets when your Airflow operators do not have built-in OpenLineage extractors and your DAG requires explicit lineage metadata to model data flow.

Yes, manual lineage annotation is applicable to both simple and complex Airflow DAGs, supporting the use of Airflow assets and OpenLineage datasets to comprehensively track data flow.
