Changes the size of the cluster. You can change the cluster’s type, or change the number or type of nodes. The default behavior is to use the elastic resize method. With an elastic resize, your cluster is available for read and write operations more quickly than with the classic resize method.
Elastic resize operations have the following restrictions:
You can only resize clusters of the following types:
dc1.large (if your cluster is in a VPC)
dc1.8xlarge (if your cluster is in a VPC)
dc2.large
dc2.8xlarge
ds2.xlarge
ds2.8xlarge
ra3.xlplus
ra3.4xlarge
ra3.16xlarge
The type of nodes that you add must match the node type for the cluster.

--cluster-identifier
(string)
The unique identifier for the cluster to resize.
--cluster-type
(string)
The new cluster type for the specified cluster.
--node-type
(string)
The new node type for the nodes you are adding. If not specified, the cluster’s current node type is used.
--number-of-nodes
(integer)
The new number of nodes for the cluster. If not specified, the cluster’s current number of nodes is used.
--classic
| --no-classic
(boolean)
A boolean value indicating whether the resize operation is using the classic resize process. If you don’t provide this parameter or set the value to
false
, the resize type is elastic.
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
