Period to wait for a connection to the master node. If no response is received
before the timeout expires, the request fails and returns an error. Defaults to

Descriptionedit
This API creates or update the desired nodes. External orchestrators can use this API to let Elasticsearch know about the cluster topology, including future changes such as adding or removing nodes. Using this information, the system is able to take better decisions.
Examplesedit
In this example, a new version for the desired nodes with history Ywkh3INLQcuPT49f6kcppA is created.
This API only accepts monotonically increasing versions.
PUT /_internal/desired_nodes/Ywkh3INLQcuPT49f6kcppA/100
{
"nodes" : [
{
"settings" : {
"node.name" : "instance-000187",
"node.external_id": "instance-000187",
"node.roles" : ["data_hot", "master"],
"node.attr.data" : "hot",
"node.attr.logical_availability_zone" : "zone-0"
},
"processors" : 8,
"memory" : "58gb",
"storage" : "1700gb",
"node_version" : "{version}"
}
]
}
The API returns the following result:

"replaced_existing_history_id": false
