TL;DR — Ticket Booking System

Design a ticket booking system like Ticketmaster for events such as concerts, sports, and theater. When a popular event goes on sale, millions of users simultaneously try to book from a limited inventory of seats. The system must handle this thundering herd problem while ensuring no seat is double-booked and the booking process is fair. Key features: Browse events with filtering by date, venue, genre. View interactive seat map with real-time availability.
