Autoscaling adds one or more workers to get the combined CPU usage of all workers below 60%. If the CPU usage continues to climb and exceeds 60%, the process repeats until the specified maximum number of workers is reached. The upscaling process takes approximately four minutes to make the first adjustment.
Clusters automatically scale down to the minimum number of workers when the combined CPU usage of all workers drops below 60%. Autoscaling removes one or more workers until CPU usage approaches 60%. The downscaling process takes approximately 15 minutes to make the first adjustment.
To configure autoscaling, you must have the privileges to create and edit a cluster. By default, the accountadmin role has the privileges to configure autoscaling.
You can configure autoscaling when creating a new cluster or when editing an existing cluster.
In the navigation, click Admin > Clusters.
Click Create cluster. See Create a cluster for details.
