// Creates an Amazon Forecast dataset. The information about the dataset that you
// provide helps Forecast understand how to consume the data for model training.
// This includes the following:
//
// * DataFrequency - How frequently your historical
// time-series data is collected.
//
// * Domain and DatasetType - Each dataset has an
// associated dataset domain and a type within the domain. Amazon Forecast provides
// a list of predefined domains and types within each domain. For each unique
// dataset domain and type within the domain, Amazon Forecast requires your data to
// include a minimum set of predefined fields.
//
// * Schema - A schema specifies the
// fields in the dataset, including the field name and data type.
//
// After creating a
// dataset, you import your training data into it and add the dataset to a dataset
// group. You use the dataset group to create a predictor. For more information,
// see Importing datasets
// (https://docs.aws.amazon.com/forecast/latest/dg/howitworks-datasets-groups.html).
// To get a list of all your datasets, use the ListDatasets
// (https://docs.aws.amazon.com/forecast/latest/dg/API_ListDatasets.html)
// operation. For example Forecast datasets, see the Amazon Forecast Sample GitHub
// repository (https://github.com/aws-samples/amazon-forecast-samples). The Status
// of a dataset must be ACTIVE before you can import training data. Use the
// DescribeDataset
// (https://docs.aws.amazon.com/forecast/latest/dg/API_DescribeDataset.html)
// operation to get the status.

type CreateDatasetInput struct {

	// A name for the dataset.
	//
	// This member is required.
	DatasetName *string

	// The dataset type. Valid values depend on the chosen Domain.
	//
	// This member is required.
	DatasetType types.DatasetType

	// The domain associated with the dataset. When you add a dataset to a dataset
	// group, this value and the value specified for the Domain parameter of the
	// CreateDatasetGroup
	// (https://docs.aws.amazon.com/forecast/latest/dg/API_CreateDatasetGroup.html)
	// operation must match. The Domain and DatasetType that you choose determine the
	// fields that must be present in the training data that you import to the dataset.
	// For example, if you choose the RETAIL domain and TARGET_TIME_SERIES as the
	// DatasetType, Amazon Forecast requires item_id, timestamp, and demand fields to
	// be present in your data. For more information, see Importing datasets
	// (https://docs.aws.amazon.com/forecast/latest/dg/howitworks-datasets-groups.html).
	//
	// This member is required.
	Domain types.Domain

	// The schema for the dataset. The schema attributes and their order must match the
	// fields in your data. The dataset Domain and DatasetType that you choose
	// determine the minimum required fields in your training data. For information
	// about the required fields for a specific dataset domain and type, see Dataset
	// Domains and Dataset Types
	// (https://docs.aws.amazon.com/forecast/latest/dg/howitworks-domains-ds-types.html).
	//
	// This member is required.
	Schema *types.Schema

	// The frequency of data collection. This parameter is required for
	// RELATED_TIME_SERIES datasets. Valid intervals are an integer followed by Y
	// (Year), M (Month), W (Week), D (Day), H (Hour), and min (Minute). For example,
	// "1D" indicates every day and "15min" indicates every 15 minutes. You cannot
	// specify a value that would overlap with the next larger frequency. That means,
	// for example, you cannot specify a frequency of 60 minutes, because that is
	// equivalent to 1 hour. The valid values for each frequency are the following:
	//
	// *
	// Minute - 1-59
	//
	// * Hour - 1-23
	//
	// * Day - 1-6
	//
	// * Week - 1-4
	//
	// * Month - 1-11
	//
	// * Year
	// - 1
	//
	// Thus, if you want every other week forecasts, specify "2W". Or, if you want
	// quarterly forecasts, you specify "3M".
	DataFrequency *string

	// An Key Management Service (KMS) key and the Identity and Access Management (IAM)
	// role that Amazon Forecast can assume to access the key.
	EncryptionConfig *types.EncryptionConfig

	// The optional metadata that you apply to the dataset to help you categorize and
	// organize them. Each tag consists of a key and an optional value, both of which
	// you define. The following basic restrictions apply to tags:
	//
	// * Maximum number of
	// tags per resource - 50.
	//
	// * For each resource, each tag key must be unique, and
	// each tag key can have only one value.
	//
	// * Maximum key length - 128 Unicode
	// characters in UTF-8.
	//
	// * Maximum value length - 256 Unicode characters in
	// UTF-8.
	//
	// * If your tagging schema is used across multiple services and resources,
	// remember that other services may have restrictions on allowed characters.
	// Generally allowed characters are: letters, numbers, and spaces representable in
	// UTF-8, and the following characters: + - = . _ : / @.
	//
	// * Tag keys and values are
	// case sensitive.
	//
	// * Do not use aws:, AWS:, or any upper or lowercase combination
	// of such as a prefix for keys as it is reserved for Amazon Web Services use. You
	// cannot edit or delete tag keys with this prefix. Values can have this prefix. If
	// a tag value has aws as its prefix but the key does not, then Forecast considers
	// it to be a user tag and will count against the limit of 50 tags. Tags with only
	// the key prefix of aws do not count against your tags per resource limit.
