Adding Nodes¶
Scenarios¶
This section describes how to add nodes to a DB instance to suit your service requirements. You can also delete a node as required. For details, see Deleting Nodes.
Precautions¶
Adding nodes may lead to the decrease of operations per second (OPS). You are advised to perform this operation during off-peak hours.
You can only add nodes when the instance status is Available or Checking restoration.
A DB instance cannot be deleted when one or more nodes are being added.
Procedure¶
On the Instance Management page, click the DB instance you wish to add nodes for.
In the Node Information area on the Basic Information page, click Add Node.
Specify Add Nodes and click Next.
By default, the specifications of new nodes are the same as the DB instance and cannot be modified.
Up to 200 nodes can be added to a GaussDB(for Cassandra) instance.
On the displayed page, confirm the node configuration details.
If you need to modify your settings, click Previous to go back to the page where you specify details.
If you do not need to modify your settings, click Submit to add the nodes.
View the result of adding nodes.
The status of the DB instance in the instance list is Adding node.
After the nodes are added, the DB instance status becomes Available.
Click the DB instance name. In the Node Information area on the Basic Information page, view the information about the new nodes.
