Add Nodes to a Cluster
You can extend a cluster by adding permanent Hadoop nodes, edge nodes, and cluster compute nodes.
See About Oracle Big Data Cloud Service Nodes for information about the different kinds of nodes.
Adding Permanent Nodes To a Cluster
You can add additional permanent nodes to a cluster after it was created and started. Permanent nodes include permanent Hadoop nodes and edge nodes.
To add permanent nodes to a cluster:
When successful, the new status appears on the Service Overview page for the cluster..
Adding and Removing Cluster Compute Nodes (Bursting)
You can add and remove cluster compute nodes at any time. This is sometimes called “bursting.”
Cluster compute nodes have processing resources (OCPUs) and memory
only, with no storage. That makes it possible to add them temporarily, when your
processing needs increase, and delete them when you no longer need them.
You don’t have to contact an Oracle representative and you don’t have
to purchase additional. entitlements. You’re charged only for the number of nodes you
allocate and only for the time they exist in the cluster. See About Oracle Big Data Cloud Service Nodes.
