Design a hotel reservation system
Problem: Design a Hotel Reservation System
Design an online hotel reservation system that enables customers to perform the following core actions:
- Search for available hotels.
- View various room types offered by a hotel.
- Create a reservation for selected rooms.
- Complete the checkout process, integrating with a third-party asynchronous payment provider.
The system design should specifically address and deep dive into these critical areas:
1. Availability Search
Given a specific hotel, a desired check-in date, a check-out date, the party size, and the quantity of rooms required, the system must accurately return only those room types that are available for every single night within the requested date range.
2. Checkout and Payment Timeout Handling
During the checkout process, the system must robustly distinguish and correctly handle two distinct timeout scenarios related to the third-party asynchronous payment provider:
- User Abandonment: The user initiates checkout but never completes the payment, leading to the checkout session timing out.
- Delayed Payment Confirmation: The user successfully completes payment with the third-party provider, but the asynchronous payment confirmation response arrives after the system's configured timeout period.
Candidates are expected to discuss functional requirements, define appropriate APIs, design data models, consider consistency guarantees, implement concurrency control mechanisms, detail timeout handling strategies, and address overall system scalability.

Core dilemma
Balancing real-time, accurate room availability (requiring strong consistency and robust concurrency control) with the eventual consistency and reliability challenges introduced by asynchronous third-party payments and distributed systems, all while preventing overbooking and ensuring a smooth user experience.
