+Lineage Backend
+---------------
+
+It's possible to push the lineage metrics to a custom backend by providing an
instance of a LinageBackend in the config:
+
+.. code-block:: ini
+
+ [lineage]
+ backend = my.lineage.CustomBackend
+
+The backend should inherit from ``airflow.lineage.LineageBackend``.
+
+.. code-block:: python
+
+ from airflow.lineage.backend import LineageBackend
+
+ class ExampleBackend(LineageBackend):
+ def send_lineage(self, operator=None, inlets=None, outlets=None,
context=None):
Review comment:

def send_lineage(self, operator, inlets=None, outlets=None,
context=None):
