AWS::Redshift::Cluster

Specifies a cluster. A cluster is a fully managed data warehouse that consists of a set of compute nodes.

To create a cluster in Virtual Private Cloud (VPC), you must provide a cluster subnet group name. The cluster subnet group identifies the subnets of your VPC that Amazon Redshift uses when creating the cluster. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:
