Design a Rental Marketplace Backend
Design the backend system for a large-scale vacation-rental marketplace, similar to platforms like Airbnb.
Core System Requirements
The system must support the following functionalities:
- Home Page Experience: Display popular destinations and personalized listing recommendations to users.
- Advanced Search: Enable users to search across millions of listings using various criteria, including location, travel dates, guest count, price range, and amenities.
- Accurate Availability & Booking: Provide precise availability checks for listings and facilitate the creation of new bookings.
Performance and Scale Requirements
- Handle high traffic volumes.
- Ensure low-latency reads.
- Operate at a global scale.
Discussion Points
The design discussion should cover the following key areas:
- APIs and Data Models: Define the core APIs and data models for essential entities such as listings, calendars, bookings, users, and recommendations.
- Search Indexing: Detail the mechanics of search indexing, including geo-spatial search capabilities, filtering mechanisms, ranking algorithms, and pagination strategies.
- Availability Management: Explain how to maintain fresh availability information within search results while simultaneously preventing double-booking scenarios under concurrent requests.
- Storage and Infrastructure: Discuss appropriate storage choices, caching strategies, data partitioning, replication techniques, and failure handling mechanisms.
- Machine Learning Integration: Describe how machine learning services can be integrated for home page recommendations and search ranking, ensuring the core system remains available even if ML services experience failures.
