Scale in a cluster following these steps: Log in to the Stream Compute Service console, identify the target cluster from the cluster list in Compute resources, and select Adjust configuration on the cluster details page. Adjust Target CUs to your desired value, confirm the fees, select I have read and agree to Configuration Adjustment Costs of Pay-As-You-Go Clusters, and click Confirm. After you confirm the order, the cluster scale-in starts. During scale-in, existing jobs on the cluster may be affected and thus restarted. For scale-in refunds, see Configuration Adjustments.
Note
The total number of CUs cannot be smaller than the number of CUs in use or than 12.
When setting Target CUs, you need to set it to the total number of CUs after scale-in, but not the number of CUs to remove.
