Distributed Multi-Tenant Inventory Reservation
Design a reservation system for a global e-commerce platform that hosts 'Flash Sales' for various brands. The system must prevent over-selling of items with limited stock (e.g., 100 units) when millions of users attempt to purchase simultaneously. It must support temporary 'carts' where items are held for 10 minutes before being released back to the pool.
