Скачать или смотреть Database Sharding Explained: Scale Apps to Millions of Users

Ever wondered how massive applications handle millions of concurrent users without crashing? The answer often lies in a powerful architectural pattern known as Database Sharding. In this video, we break down the "Scaling Wall" and explore exactly how horizontal partitioning works to distribute data across multiple servers.

We will cover the core mechanics of sharding, including shard keys and routing logic, and compare horizontal scaling against vertical scaling. While sharding offers massive scalability and high availability, it comes with hidden complexities like hotspots and operational overhead. Find out if this complex solution is right for your system or if you should stick to simpler methods like caching and read replicas.
