Scaling Out a Cluster

You can scale out a cluster by adding nodes to increase capacity and handle increasing workloads.

To scale out a cluster:
  1. Open the Oracle Data Hub Cloud Service Console.
  2. Click the name of the cluster you want to scale out.
    An overview page with cluster details is displayed.
  3. From the Menu icon menu for the cluster at the top of the page, select Scale Out.
    The Scale Out window is displayed.
  4. Scale out the cluster as desired:
    • Number of Cassandra Nodes to Add: Number of nodes you want to add, between 0 and 20.
  5. Click Scale Out.
    Nodes are added. During this process the cluster goes into Maintenance mode and, once the scale-out operation is complete, becomes operational again.
