Previously, deleted rows were archived in batches of max_rows parents + their child rows in a single database transaction. It limited how high a value of max_rows could be specified by the user because of the size of the database transaction it could generate. Symptoms of the behavior were exceeding the maximum configured packet size of the database or timing out due to a deadlock. The behavior has been changed to archive batches of complete parent + child rows trees while limiting each batch when it has reached >= max_rows records. This allows the size of the database transaction to be controlled by the user and enables more rows to be archived per invocation of "nova-manage db archive_deleted_rows" when there are a large number of foreign key related records.
