Scale out 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 and pay successfully, the cluster scale-out starts. During the scale-out, existing jobs on the cluster are not affected, and you can also create new jobs on it. After scale-out is complete, added CUs will be available for use. For scale-out fees, see Configuration Adjustments.
Note
Considering the performance of underlying machines, you can add up to 300 CUs at a time, and a single cluster can have a maximum of 800 CUs by default. If you need to raise the limit, contact us.
