After creating a Serverless cluster instance, you can modify the cluster's architecture and computing power configuration, and enable/disable automatic suspension by adjusting the configuration in the console.
Prerequisites
A Serverless cluster has been created.
The cluster status is started.
Modify the cluster's architecture
A Serverless cluster supports two architectures: single-node and cluster editions. The single-node edition has only one read/write instance. After purchase, you can switch to the cluster edition by adding read-only instances through configuration adjustments in the console. The cluster edition includes one read/write instance and 1 - 8 optional read-only instances. After purchase, you can switch back to the single-node edition through configuration adjustments in the console. The corresponding operations are as follows:
