+Execute database maintenance tasks
+----------------------------------
+Cleanup stale records from nova database to make it smaller.
+This is helpful before any upgrade activity.
+It is safe to execute it generally without maintenance window same as online db_sync.
+
+Enable this pillar:
+
+.. code-block:: yaml
+
+   nova:
+     controller:
+       db_purge:
+         enabled: True
+
+Execute state nova.db.db_cleanup to purge stale records:
+
+.. code-block:: bash
+
+   salt -C 'I@nova:controller:role:primary' state.apply nova.db.db_cleanup -l debug
+
+Starting from rocky release it is possible to pass days parameter.
+If you skip setting it, all records would be archived/purged:
+
+.. code-block:: yaml
+
+   nova:
+     controller:
+       db_purge:
+         enabled: True
+         days: 45
+
+Control pre-rocky releases parameters:
+
+.. code-block:: yaml
+
+   nova:
+     controller:
+       db_purge:
+         enabled: True
+         max_rows: 1000
+         verbose: True
+
+Control rocky+ releases parameters:
+'days' and 'all' parameters are mutually exclusive.
+
+.. code-block:: yaml
+
+   nova:
+     controller:
+       db_purge:
+         enabled: True
+         all: True
+         verbose: True
+         all_cells: True
