# DescribeNodeConfigurationOptions
<a name="API_DescribeNodeConfigurationOptions"></a>

Returns properties of possible node configurations such as node type, number of nodes, and disk usage for the specified action type.

## Request Parameters
<a name="API_DescribeNodeConfigurationOptions_RequestParameters"></a>

 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 ** ActionType **   
The action type to evaluate for possible node configurations. Specify "restore-cluster" to get configuration combinations based on an existing snapshot. Specify "recommend-node-config" to get configuration recommendations based on an existing cluster or snapshot. Specify "resize-cluster" to get configuration combinations for elastic resize based on an existing cluster.   
Type: String  
Valid Values: `restore-cluster | recommend-node-config | resize-cluster`   
Required: Yes

 ** ClusterIdentifier **   
The identifier of the cluster to evaluate for possible node configurations.  
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

 **Filter.NodeConfigurationOptionsFilter.N**   
A set of name, operator, and value items to filter the results.  
Type: Array of [NodeConfigurationOptionsFilter](API_NodeConfigurationOptionsFilter.md) objects  
Required: No

 ** Marker **   
An optional parameter that specifies the starting point to return a set of response records. When the results of a [DescribeNodeConfigurationOptions](#API_DescribeNodeConfigurationOptions) request exceed the value specified in `MaxRecords`, AWS returns a value in the `Marker` field of the response. You can retrieve the next set of response records by providing the returned marker value in the `Marker` parameter and retrying the request.   
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

 ** MaxRecords **   
The maximum number of response records to return in each call. If the number of remaining response records exceeds the specified `MaxRecords` value, a value is returned in a `marker` field of the response. You can retrieve the next set of records by retrying the command with the returned marker value.   
Default: `500`   
Constraints: minimum 100, maximum 500.  
Type: Integer  
Required: No

 ** OwnerAccount **   
The AWS account used to create or copy the snapshot. Required if you are restoring a snapshot you do not own, optional if you own the snapshot.  
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

 ** SnapshotArn **   
The Amazon Resource Name (ARN) of the snapshot associated with the message to describe node configuration.  
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

 ** SnapshotIdentifier **   
The identifier of the snapshot to evaluate for possible node configurations.  
Type: String  
Length Constraints: Maximum length of 2147483647.  
Required: No

## Response Elements
<a name="API_DescribeNodeConfigurationOptions_ResponseElements"></a>

The following elements are returned by the service.

 ** Marker **   
A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned marker value in the `Marker` parameter and retrying the command. If the `Marker` field is empty, all response records have been retrieved for the request.   
Type: String  
Length Constraints: Maximum length of 2147483647.

 **NodeConfigurationOptionList.NodeConfigurationOption.N**   
A list of valid node configurations.  
Type: Array of [NodeConfigurationOption](API_NodeConfigurationOption.md) objects

## Errors
<a name="API_DescribeNodeConfigurationOptions_Errors"></a>

HTTP Status Code: 400

 ** ClusterNotFound **   
The `ClusterIdentifier` parameter does not refer to an existing cluster.   
HTTP Status Code: 404

 ** ClusterSnapshotNotFound **
