        Indicates the database engine version.

      • DatabaseName (string) –

        The default database name within the new global cluster.

      • StorageEncrypted (boolean) –

        The storage encryption setting for the global cluster.

      • DeletionProtection (boolean) –

        The deletion protection setting for the new global cluster.

      • GlobalClusterMembers (list) –

        The list of cluster IDs for secondary clusters within the global cluster. Currently limited to one item.

        • (dict) –

          A data structure with information about any primary and secondary clusters associated with an Amazon DocumentDB global clusters.

          • DBClusterArn (string) –

            The Amazon Resource Name (ARN) for each Amazon DocumentDB cluster.

          • Readers (list) –

            The Amazon Resource Name (ARN) for each read-only secondary cluster associated with the Aurora global cluster.

            • (string) –

          • IsWriter (boolean) –

            Specifies whether the Amazon DocumentDB cluster is the primary cluster (that is, has read-write capability) for the Amazon DocumentDB global cluster with which it is associated.
