4.2.2 Editing a HeatWave Cluster

Use the Console to edit the HeatWave cluster. You can change the display name, description, the shape of the nodes, or the number of nodes for the HeatWave Cluster.

1. In the HeatWave Console, select the Resources tab, and then the HeatWave Clusters tab.
2. In the list of HeatWave Clusters, find the HeatWave Cluster you want to edit, and do one of the following:
   • Click the row of the HeatWave Cluster to highlight it, and click Edit HeatWave Cluster from the Actions menu.
   • Click the name of the HeatWave Cluster to open the Details page and click Edit HeatWave Cluster from the Actions menu.
3. On the Edit HeatWave Cluster panel, update the following information as needed:
   • Basic information
     • Display Name: Change the name of the HeatWave Cluster as needed.
     • Description: Change the description of the HeatWave Cluster as needed.
   • HeatWave Cluster Configuration: You can select either of the following options by the toggle buttons:
     • Manually configure cluster. Configure the cluster then by filling in the following information.
       • Shape: Select a HeatWave node shape. For information about supported shapes, see Supported Shapes.

         Note:

         If you intend to use HeatWave AutoML functionality, the HeatWave.256GB node shape is recommended. The HeatWave.16GB node shape may not have enough memory for training on large data sets. If you see error messages about this (such as ML003024), use the larger shape instead.
       • Cluster Size: Change the number of HeatWave nodes as needed. The minimum number is 1, and the maximum number depends on the following conditions:

         • For the Heatwave.16GB node shape: 16.
         • For the HeatWave.256GB node shape:
           • If HeatWave Lakehouse is not enabled: 128.
           • If HeatWave Lakehouse is enabled: 512.
     • Automatically configure cluster. Configure the cluster by clicking Estimate memory size to estimate the required cluster size using HeatWave Autopilot. See more details in Estimating Cluster Size with HeatWave Autopilot.
   • Check the HeatWave Cluster configuration in the Summary section. Go back to the steps above to make changes if needed.
4. Click Save.

Note:

The HeatWave Cluster will be offline while the configuration is being changed.
