// Creates a new Amazon Aurora DB cluster or Multi-AZ DB cluster. If you create an
// Aurora DB cluster, the request creates an empty cluster. You must explicitly
// create the writer instance for your DB cluster using the CreateDBInstance (https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_CreateDBInstance.html)
// operation. If you create a Multi-AZ DB cluster, the request creates a writer and
// two reader DB instances for you, each in a different Availability Zone. You can
// use the ReplicationSourceIdentifier parameter to create an Amazon Aurora DB
// cluster as a read replica of another DB cluster or Amazon RDS for MySQL or
// PostgreSQL DB instance. For more information about Amazon Aurora, see What is
// Amazon Aurora? (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/CHAP_AuroraOverview.html)

// ReplicationSourceIdentifier parameter to create a Multi-AZ DB cluster read
// replica with an RDS for MySQL or PostgreSQL DB instance as the source. For more
// information about Multi-AZ DB clusters, see Multi-AZ DB cluster deployments (https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/multi-az-db-clusters-concepts.html)
