Скачать или смотреть I Solved BookMyShow Seat Clash! Full LLD + Lock Expiry + Why Redis is Must

In this video, I’ve broken down the BookMyShow seat booking system from scratch.

You’ll see how the booking flow works, how to handle concurrent seat selections, and why we need Redis for distributed locking.

We start with understanding the problem, then gather complete requirements, and design a proper UML class diagram covering entities like Seat, Show, Booking, and LockManager.

You’ll learn how to:

1. Prevent 2 users from booking the same seat
2. Handle lock ownership and expiry
3. Build a custom in-memory lock manager
4. Use Factory + Strategy design patterns for payments

This is the most complete and intuitive LLD explanation of BookMyShow on YouTube.

If you're preparing for system design interviews or just want to go deep into how real-world booking platforms work, this is for you.
