                "full"
                    A boolean. When set to true, means clean everything possible.

                    A boolean value indicating whether or not to fix the
                    transactions in the database as well.

                "check_nodes"
                    A boolean, when set to true means check the nodes.

                    A boolean, when set to true informs the cleaner to gracefully
                    stop its current activities if any cleaning is taking place.
