Create custom OpenLineage extractors for Airflow operators. Use when the user needs lineage from unsupported or third-party operators, wants column-level lineage, or needs complex extraction logic beyond what inlets/outlets provide.

# Creating OpenLineage Extractors
This skill guides you through creating custom OpenLineage extractors to capture lineage from Airflow operators that don't have built-in support.
> **Reference:** See the [OpenLineage provider developer guide](https://airflow.apache.org/docs/apache-airflow-providers-openlineage/stable/guides/developer.html) for the latest patterns and list of supported operators/hooks.
## When to Use Each Approach
| Scenario | Approach |
|----------|----------|
| Operator you own/maintain | **OpenLineage Methods** (recommended, simplest) |
| Third-party operator you can't modify | Custom Extractor |
| Need column-level lineage | OpenLineage Methods or Custom Extractor |
| Complex extraction logic | OpenLineage Methods or Custom Extractor |
