batchAddClusterNodes   
  abstract suspend fun batchAddClusterNodes(input: BatchAddClusterNodesRequest): BatchAddClusterNodesResponse
Adds nodes to a HyperPod cluster by incrementing the target count for one or more instance groups. This operation returns a unique NodeLogicalId for each node being added, which can be used to track the provisioning status of the node. This API provides a safer alternative to UpdateCluster for scaling operations by avoiding unintended configuration changes.
This API is only supported for clusters using Continuous as the NodeProvisioningMode.
