Managing OpenSearch node groups
In OpenSearch clusters, you cannot add, update, or delete individual nodes. Instead, you can manage node groups:
- Getting a list of node groups in a cluster
- Adding a node group to a cluster
- Updating a node group configuration
- Deleting a node group
Warning
In each cluster, the first node group has the type Dashboards

group in the cluster.
