Database Zero Downtime Online Upgrade With TiProxy

Lab Description

This hands-on lab showcases TiDB's seamless online rolling upgrade capability, avoiding disruptions to client applications — a common issue with traditional database upgrades. TiDB's cloud-native, loosely coupled architecture allows component-by-component, instance-by-instance upgrades. TiProxy enhances this by decoupling client sessions from stateless TiDB servers. During TiDB server reboots for upgrades, TiProxy seamlessly migrates sessions to active instances, ensuring uninterrupted client operations throughout the upgrade process.
