globalClusterIdentifier

If you are configuring an Aurora global database cluster and want your Aurora DB cluster to be a secondary member in the global database cluster, specify the global cluster ID of the global database cluster. To define the primary database cluster of the global cluster, use the AWS::RDS::GlobalCluster resource. If you aren't configuring a global database cluster, don't specify this property. To remove the DB cluster from a global database cluster, specify an empty value for the `GlobalClusterIdentifier` property. For information about Aurora global databases, see Working with Amazon Aurora Global Databases in the Amazon Aurora User Guide. Valid for: Aurora DB clusters only
