📅 Two people, same apartment, same dates, same second—yet Airbnb avoids double bookings. When? During booking. Where? On Airbnb’s platform. How? By holding reservations in a pending state and processing payment asynchronously. If payment fails, the reservation hold expires, preventing double bookings and chaos. Why? Inventory is a state machine under pressure, not just data. This approach differentiates scalable systems from those that break. #SystemDesign #SaaSArchitecture #Airbnb #Scalability
