Delete lineage

Production-ready lineage delete API with enhanced capabilities and improved performance.

Available since: RELEASE 2025.3.3

This API introduces support for an optional dataflow_key parameter and is the recommended method for deleting lineage information.

The request allows deletion of a lineage edge between a source object and a target object.

• If dataflow_key is not provided, the API deletes the lineage edge between the source and target regardless of any associated dataflows.

• If dataflow_key is provided, the API deletes the edge only if it is associated with the specified dataflow and no others.

• If the edge is also associated with a different dataflow, the request is rejected with a validation error.
