SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Annotate Airflow tasks with data lineage using inlets and outlets to add metadata when operators do not have built-in OpenLineage extractors.

Core Features & Use Cases

Manual lineage annotation using inlets and outlets for operators without extractors.
Supports OpenLineage Datasets and Airflow Assets / Datasets to model inputs and outputs.
Use Case: Add lineage to a simple BashOperator by declaring inputs and outputs, enabling downstream lineage tracking.

Quick Start

Use the annotating-task-lineage skill to add manual lineage to a task by defining inlets and outlets in the operator.

FAQPage Schema

How do I add data lineage to Airflow tasks when the operator lacks a built-in OpenLineage extractor?▼

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.

What is manual lineage annotation using inlets and outlets in Airflow?▼

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.

Can I use OpenLineage datasets to track lineage for a simple BashOperator in Airflow?▼

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.

When do I need to manually specify inlets and outlets for Airflow lineage tracking?▼

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.

Does manual lineage annotation work with complex Airflow DAGs that use Airflow assets?▼

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.
