Scaling In a DDM Instance
Scenarios
This section describes how to scale in a DDM instance as service data volume decreases.
- Scaling in yearly/monthly DDM instances is not supported.
- Scale in your DDM instance during off-peak hours. For pay-per-use instances, nodes are removed after the scale-in request is submitted.
- Make sure that the associated data nodes are normal and not undergoing other operations.
- At least one node should be left for a DDM instance.
- After a read-only group is created, the entry for removing nodes will be moved to the operation column of the group.
Procedure
- In the instance list, locate the DDM instance that you want to scale in and click its name. Click Scale In.
- On the displayed page, view the current instance configuration and specify the number of nodes to be removed.
- Click Next.
- On the displayed page, click Submit if all configurations are correct.
