Designing Uber: Geospatial Indexing and Real-Time Matching
A developer outlines Uber's system design, focusing on geospatial indexing with hexagonal grids (H3) for location tracking and real-time driver-rider matching. The post explains how surge pricing acts as a load-shedding mechanism, and emphasizes separating hot, short-lived location data from strongly consistent transactional stores. It highlights trade-offs like denormalization and city-based sharding for scalability.
