Description
Modifies the settings for a cluster. For example, you can add another security or parameter group, update the preferred maintenance window, or change the master user password. Resetting a cluster password or modifying the security groups associated with a cluster do not need a reboot. However, modifying a parameter group requires a reboot for parameters to take effect. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide.
You can also change node type and the number of nodes to scale up or down the cluster. When resizing a cluster, you must specify both the number of nodes and the node type even if one of the parameters does not change.

-ClusterType <String>
The new cluster type.When you submit your cluster resize request, your existing cluster goes into a read-only mode. After Amazon Redshift provisions a new cluster based on your resize requirements, there will be outage for a period while the old cluster is deleted and your connection is switched to the new cluster. You can use DescribeResize to track the progress of the resize request. Valid Values:

| Position? | Named |
| Accept pipeline input? | False |
-ClusterVersion <String>
The new version number of the Amazon Redshift engine to upgrade to.For major version upgrades, if a non-default cluster parameter group is currently in use, a new cluster parameter group in the cluster parameter group family for the new version must be specified. The new cluster parameter group can be the default for that cluster parameter group family. For more information about parameters and parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Cluster Management Guide.Example:

| Position? | Named |
| Accept pipeline input? | False |
-Encrypted <Boolean>
Indicates whether the cluster is encrypted. If the cluster is encrypted and you provide a value for the
KmsKeyId parameter, we will encrypt the cluster with the provided KmsKeyId. If you don't provide a KmsKeyId, we will encrypt with the default key. In the China region we will use legacy encryption if you specify that the cluster is encrypted. | Required? | False |

Common Credential and Region Parameters
-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key
if the corresponding session token is supplied to the -SessionToken parameter.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information,

| Position? | Named |
| Accept pipeline input? | False |
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)
If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.
If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.
As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing
credential information. The profile is expected to be found in the secure credential
file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also
specify the name of a profile stored in the .ini-format credential file used with
the AWS CLI and other AWS SDKs.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile.
Contains the network credentials to be supplied during authentication with the
configured identity provider's endpoint. This parameter is not required if the
user's default network identity can or should be used during authentication.
| Required? | False |
| Position? | Named |
| Accept pipeline input? | False |
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key
if the corresponding session token is supplied to the -SessionToken parameter.

-EndpointUrl <String>
The endpoint to make the call against.
Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
| Required? | False |
| Position? | Named |
