Database Seamless Scalability

Lab Description

TiDB uses a distributed architecture design that separates computing (SQL layer) from storage (TiKV layer), making it easy to scale horizontally. You can add more nodes to a TiDB cluster or remove existing nodes to change its capacity and performance without causing significant downtime or interruption to your application. This lab show you how to scale in/out the SQL layer and the storage layer. In addition, this lab also discusses the best practice to achieve application zero downtime when scaling in the SQL layer.
