Type: *string



Type: *bool

If true, major version upgrades can be applied during the maintenance window to the Amazon Redshift engine that is running on the cluster.

When a new major version of the Amazon Redshift engine is released, you can request that the service automatically apply upgrades during the maintenance window to the Amazon Redshift engine that is running on your cluster.

Default: true


Type: *int64

The number of days that automated snapshots are retained. If the value is 0, automated snapshots are disabled. Even if automated snapshots are disabled, you can still create manual snapshots when you want with CreateClusterSnapshot.

Default: 1

Constraints: Must be a value from 0 to 35.


Type: *string

The EC2 Availability Zone (AZ) in which you want Amazon Redshift to provision the cluster. For example, if you have several EC2 instances running in a specific Availability Zone, then you might want the cluster to be provisioned in the same zone in order to decrease network latency.

Default: A random, system-chosen Availability Zone in the region that is specified by the endpoint.

Example: us-east-1d

Constraint: The specified Availability Zone must be in the same region as the current endpoint.


Type: *string

A unique identifier for the cluster. You use this identifier to refer to the cluster for any subsequent cluster operations such as deleting or modifying. The identifier also appears in the Amazon Redshift console.


  • Must contain from 1 to 63 alphanumeric characters or hyphens.

  • Alphabetic characters must be lowercase.

  • First character must be a letter.

  • Cannot end with a hyphen or contain two consecutive hyphens.

Type: *string

The version of the Amazon Redshift engine software that you want to deploy on the cluster.

The version selected runs on all the nodes in the cluster.

Constraints: Only version 1.0 is currently available.

Example: 1.0


Type: *string

The name of the first database to be created when the cluster is created.

To create additional databases after the cluster is created, connect to the cluster with a SQL client and use SQL commands to create a database. For more information, go to Create a Database ( in the Amazon Redshift Database Developer Guide.

Default: dev


  • Must contain 1 to 64 alphanumeric characters.

  • Must contain only lowercase letters.


Type: *string

The Elastic IP (EIP) address for the cluster.

Constraints: The cluster must be provisioned in EC2-VPC and publicly-accessible through an Internet gateway. For more information about provisioning clusters in EC2-VPC, go to Supported Platforms to Launch Your Cluster ( in the Amazon Redshift Cluster Management Guide.


Type: *bool

If true, the data in the cluster is encrypted at rest.

Default: false


Type: *bool

An option that specifies whether to create the cluster with enhanced VPC routing enabled. To create a cluster that uses enhanced VPC routing, the cluster must be in a VPC. For more information, see Enhanced VPC Routing ( in the Amazon Redshift Cluster Management Guide.

If this option is true, enhanced VPC routing is enabled.

Default: false


Type: *string

Specifies the name of the HSM client certificate the Amazon Redshift cluster uses to retrieve the data encryption keys stored in an HSM.


Type: *string

Specifies the name of the HSM configuration that contains the information the Amazon Redshift cluster can use to retrieve and store keys in an HSM.


Type: []*string

A list of AWS Identity and Access Management (IAM) roles that can be used by the cluster to access other AWS services. You must supply the IAM roles in their Amazon Resource Name (ARN) format. You can supply up to 10 IAM roles in a single request.

A cluster can have up to 10 IAM roles associated with it at any time.


Type: *string

The AWS Key Management Service (KMS) key ID of the encryption key that you want to use to encrypt data in the cluster.


Type: *string

An optional parameter for the name of the maintenance track for the cluster. If you don't provide a maintenance track name, the cluster is assigned to the current track.


Type: *int64

The default number of days to retain a manual snapshot. If the value is -1, the snapshot is retained indefinitely. This setting doesn't change the retention period of existing snapshots.

The value must be either -1 or an integer between 1 and 3,653.


Type: *string

The password associated with the master user account for the cluster that is being created.

Type: *int64

The number of compute nodes in the cluster. This parameter is required when the ClusterType parameter is specified as multi-node.

For information about determining how many nodes you need, go to Working with Clusters ( in the Amazon Redshift Cluster Management Guide.

If you don't specify this parameter, you get a single-node cluster. When requesting a multi-node cluster, you must specify the number of nodes that you want in the cluster.

Default: 1

Constraints: Value must be at least 1 and no more than 100.
