Overview

Managing data nodes is managing RDS for MySQL or GaussDB(for MySQL) instances that are associated with your DDM instance. You can view the instance status, storage, class, and read weight, configure read weights, and create read replicas on the data node management page.

You can set read weights for multiple data nodes in the list at the same time. If a data node has no read replicas, you cannot set read weights for its primary RDS instance.

If your DDM instance is associated with multiple data nodes, you can set a read weight for the first data node and then click Synchronize to synchronize the settings of the first node to other nodes with the same read replicas. If each data node has different read replicas, set the weights manually.
