	// Specifies the type of KDB database that is being created. The following types
	// are available:
	//   - HDB – A Historical Database. The data is only accessible with read-only
	//   permissions from one of the FinSpace managed kdb databases mounted to the
	//   cluster.
	//   - RDB – A Realtime Database. This type of database captures all the data from
	//   a ticker plant and stores it in memory until the end of day, after which it
	//   writes all of its data to a disk and reloads the HDB. This cluster type requires
	//   local storage for temporary storage of data during the savedown process. If you
	//   specify this field in your request, you must provide the
	//   savedownStorageConfiguration parameter.
	//   - GATEWAY – A gateway cluster allows you to access data across processes in
	//   kdb systems. It allows you to create your own routing logic using the
	//   initialization scripts and custom code. This type of cluster does not require a
	//   writable local storage.

	// The details of the custom code that you want to use inside a cluster when

	// The version of FinSpace managed kdb to run.
	ReleaseLabel *string

	// The size and type of the temporary storage that is used to hold data during the
	// savedown process. This parameter is required when you choose clusterType as
	// RDB. All the data written to this storage space is lost when the cluster node is

	SavedownStorageConfiguration *types.KxSavedownStorageConfiguration

	// The status of cluster creation.
	//   - PENDING – The cluster is pending creation.

	//   - DELETED – The cluster has been deleted.
	//   - DELETE_FAILED – The cluster failed to delete.
