The configurations of an instance group is displayed in the List of RDS instances and DTS instance List sections.
List of RDS instances
This section shows the basic information about the primary and secondary instances in the instance group, including their running status, region, zone, role, and creation time. You can view and manage the instances in this section.
You can click the ID of an instance to view the instance details.
You can click Add Secondary Instance in the upper-right corner of this section to add a secondary instance to the instance group, or click Remove in the Actions column corresponding to a secondary instance to remove it from the instance group. For more information, see Add or remove a secondary instance.
DTS instance List
This section shows the details of all DTS synchronization tasks of the instance group, including their synchronization direction, region, running status, latency, and creation time. You can view and manage the synchronization tasks between the primary and secondary instances in this section.
You can click Details of a synchronization task to view its detailed information.
When you remove the secondary instance from an instance group, the DTS data synchronization task associated with the secondary instance is automatically released. You do not need to manually release the task.
