Scaling Out a Cluster
Function
This API is used to add instances (Elasticsearch instances only) to a cluster. This API can only scale out clusters that only have common nodes. You cannot use this API to scale out a cluster that has master, client, or cold data nodes. For details about how to configure the number and storage capacity of instances in a cluster, see the API for Adding Instances and Expanding Instance Storage Capacity.
