Change the node specifications for any engine in a Lindorm instance—upgrade when capacity falls short, or downgrade when resources are over-provisioned.
Prerequisites
Before you begin, ensure that you have:
-
A Lindorm instance with a status of Running. See Create an instance.
Usage notes
-
Service impact: A specification change may cause brief service jitter. During the change, the instance status shows Changing Specifications. Reads and writes remain available, but you cannot perform other management operations such as enabling services or changing nodes. Schedule the change during off-peak hours to minimize impact.
-
Before downgrading: Confirm that the target specifications can handle your actual workload. Consider multiple factors beyond read/write volumes. If you need help with the evaluation, submit a ticket.
