YouTube started with a single MySQL database and eventually grew to support billions of users. This session walks through the real scalability challenges they faced and explains how Vitess helped solve them.

We’ll cover practical, real-world problems like replication bottlenecks, sharding complexity, stale reads, and protecting the database from overload, along with the architectural tradeoffs behind each approach.

What We’ll Cover

✅ Why traditional MySQL leader-follower replication hit limits

✅ How caching and binlog streaming temporarily helped

✅ The core problems of sharding at scale

✅ How Vitess abstracts sharding, improves performance, and protects MySQL

Pre-Requisites / Pre-Read (Recommended, Not Mandatory)

Basic understanding of relational databases (MySQL)
Familiarity with read/write queries
