Changing the Specifications of a Specified Node Type¶
This API is used to modify cluster specifications. The following node types can be changed:
ess: data node
ess-cold: cold data node
ess-client: client node
ess-master: master node
Project ID. For details, see Obtaining a Project ID and Name.
ID of the cluster whose specifications you want to change.
Type of the cluster node you want to modify.
Whether to check replicas. The value can be true or false. The check is enabled by default.
Master and client nodes are not data nodes, so they do not need to check replicas no matter this parameter is set to true or false.
ID of the new flavor. This parameter is obtained by calling the Obtaining the List of Instance Flavors API. The API compares the values of the name attribute and obtains the ID of the flavor higher than the current flavor. Only the node specifications of the same Elasticsearch engine version can be changed.
"needCheckReplica" : false,
"newFlavorId" : "35b060a4-f152-48ce-8773-36559ceb81f2"
