Distributed Relational Database Service - DRDS - Custom configurations of compute nodes and data nodes
Supported instances: PolarDB-X 2.0 instances. Feature description: In the default mode, the ratio of the number of compute nodes and the number of data nodes in an instance is 1:1. PolarDB-X 2.0 supports the custom configuration feature for compute nodes and data nodes. When you create a PolarDB-X 2.0 instance, you can specify the specification of compute nodes, the specification of data nodes, the number of compute nodes, and the number of data nodes based on your business requirements. The custom configuration feature can help you reduce costs.
