An empty order is an Order containing no CommerceItems (an empty shopping cart). When the ShoppingCart’s current Order is first fetched, the system tries to find an existing order. If it fails to find one, it creates a new empty transient order. If the persistOrders property of the ShoppingCart component is set to true, the order is persisted. In some cases, for example if a site typically handles many anonymous visitors, it may not be desirable to persist all empty orders to the database.
To prevent empty orders from being persisted, set the persistEmptyOrders property of the ShoppingCart component to false. It is possible to turn off empty order persistence for anonymous visitors only (a common requirement), or for logged-in visitors only (less common). To do so, set the persistOrdersForAnonymousUsers and persistEmptyOrders properties as appropriate.
