# GET /#Action=CreateDBCluster

`GET /#Action=CreateDBCluster`

Creates a new Amazon Neptune DB cluster.

You can use the `ReplicationSourceIdentifier` parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance.

Note that when you create a new cluster using `CreateDBCluster` directly, deletion protection is disabled by default (when you create a new production cluster in the console, deletion protection is enabled by default). You can only delete a DB cluster if its `DeletionProtection` field is set to `false`.

  - `MinCapacity` number, double — The minimum number of Neptune capacity units (NCUs) for a DB instance in a Neptune Serverless cluster. You can specify NCU values in half-step increments, such as 8, 8.5, 9, and so on.
  - `MaxCapacity` number, double — The maximum number of Neptune capacity units (NCUs) for a DB instance in a Neptune Serverless cluster. You can specify NCU values in half-step increments, such as 40, 40.5, 41, and so on.
