// CreateDatasetGroupRequest returns a request value for making API operation for
// Amazon Personalize.
//
// Creates an empty dataset group. A dataset group contains related datasets
// that supply data for training a model. A dataset group can contain at most
// three datasets, one for each type of dataset:
//
//    * Interactions
//
//    * Items
//
//    * Users
//
// To train a model (create a solution), a dataset group that contains an Interactions
// dataset is required. Call CreateDataset to add a dataset to the group.
//
// A dataset group can be in one of the following states:
//
//    * CREATE PENDING > CREATE IN_PROGRESS > ACTIVE -or- CREATE FAILED
//
//    * DELETE PENDING
//
// To get the status of the dataset group, call DescribeDatasetGroup. If the
// status shows as CREATE FAILED, the response includes a failureReason key,
// which describes why the creation failed.
//
// You must wait until the status of the dataset group is ACTIVE before adding
// a dataset to the group.
//
// You can specify an AWS Key Management Service (KMS) key to encrypt the datasets
// in the group. If you specify a KMS key, you must also include an AWS Identity
// and Access Management (IAM) role that has permission to access the key.
//
// APIs that require a dataset group ARN in the request
