Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

CreationTime

When the dataset was created.

Type: Timestamp

DataFrequency

The frequency of data collection.

Valid intervals are Y (Year), M (Month), W (Week), D (Day), H (Hour), 30min (30 minutes), 15min (15 minutes), 10min (10 minutes), 5min (5 minutes), and 1min (1 minute). For example, "M" indicates every month and "30min" indicates every 30 minutes.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 5.

Pattern: ^Y|M|W|D|H|30min|15min|10min|5min|1min$

DatasetArn

The Amazon Resource Name (ARN) of the dataset.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:([a-z\d-]+):forecast:.*:.*:.+

DatasetName

The name of the dataset.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 63.

Pattern: ^[a-zA-Z][a-zA-Z0-9_]*

DatasetType

The dataset type.

Type: String

Valid Values: TARGET_TIME_SERIES | RELATED_TIME_SERIES | ITEM_METADATA

Domain

The domain associated with the dataset.

Type: String

EncryptionConfig

The AWS Key Management Service (KMS) key and the AWS Identity and Access Management (IAM) role that Amazon Forecast can assume to access the key.

Type: EncryptionConfig object

LastModificationTime

When you create a dataset, LastModificationTime is the same as CreationTime. While data is being imported to the dataset, LastModificationTime is the current time of the DescribeDataset call. After a CreateDatasetImportJob operation has finished, LastModificationTime is when the import job completed or failed.

Type: Timestamp

Schema

An array of SchemaAttribute objects that specify the dataset fields. Each SchemaAttribute specifies the name and data type of a field.

Type: Schema object

Status

The status of the dataset. States include:

ACTIVE
CREATE_PENDING, CREATE_IN_PROGRESS, CREATE_FAILED
DELETE_PENDING, DELETE_IN_PROGRESS, DELETE_FAILED
UPDATE_PENDING, UPDATE_IN_PROGRESS, UPDATE_FAILED

The UPDATE states apply while data is imported to the dataset from a call to the CreateDatasetImportJob operation and reflect the status of the dataset import job. For example, when the import job status is CREATE_IN_PROGRESS, the status of the dataset is UPDATE_IN_PROGRESS.

Note

The Status of the dataset must be ACTIVE before you can import training data.

Type: String

Length Constraints: Maximum length of 256.
