Build A High-Availability System With PolarDB-X
This experiment demonstrates how to build a highly available distributed database by using a PolarDB-X cluster with Alibaba Cloud Elastic Compute Service (ECS). In the experiment, you will simulate a node failure by killing a pod to test the automatic recovery of PolarDB-X. PolarDB-X is a cloud-native distributed database that allows storage of massive amounts of data and high-concurrency, complex queries. With a shared-nothing architecture that separates storage from compute, the enterprise-level cloud-native database supports horizontal scaling, distributed transactions, and hybrid loads, and provides high availability. It is highly compatible with MySQL and its ecosystems.
