Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
needCheckReplica |
No |
Boolean |
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. |
newFlavorId |
Yes |
String |
ID of the new flavor. This parameter is obtained by calling the [Obtaining the Instance Specifications List] (ListFlavors.xml) 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. |
