To support the new Inventory Reservations feature and improve our platform's scalability, we're changing how inventory records are processed. It can now take up to 10 seconds for changes to be reflected in the availableQuantity and quantityOnStock fields of the Inventory Entry.

This change applies to Orders placed with both ReserveOnOrder and TrackOnly inventory modes. While direct API updates to inventory resources remain strongly consistent, related background updates to product availability continue to be eventually consistent.
