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 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 | | Simple table-level lineage | Inlets/Outlets (simplest, but lowest priority) | Important: Always prefer OpenLineage methods over custom extractors when possible. Extractors are harder to write, easier to diverge from operator behavior after changes, and harder to debug.
