LockerSync: Universal Third-Party Delivery Network
Design a centralized management system for a network of 100,000 smart lockers installed in various retail stores. These lockers are 'agnostic' and can be rented by any courier (FedEx, DHL, local shops) to drop off packages. The system must ensure a locker is never double-booked and can function even if a specific locker's internet connection is intermittent.
