Creating parameter groups is independent of creating clusters. You can associate a cluster with a parameter group when you create the cluster. You can also associate an existing cluster with a parameter group after the cluster is created by using ModifyCluster.
Parameters in the parameter group define specific behavior that applies to the databases you create on the cluster. For more information about managing parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Management Guide.
