CreateFeatureGroup - Amazon SageMaker Service
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with AWS services in China.

CreateFeatureGroup

Create a new FeatureGroup. A FeatureGroup is a group of Features defined in the FeatureStore to describe a Record.

The FeatureGroup defines the schema and features contained in the FeatureGroup. A FeatureGroup definition is composed of a list of Features, a RecordIdentifierFeatureName, an EventTimeFeatureName and configurations for its OnlineStore and OfflineStore. Check AWS service quotas to see the FeatureGroups quota for your AWS account.

Important

You must include at least one of OnlineStoreConfig and OfflineStoreConfig to create a FeatureGroup.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Description

A free-form description of a FeatureGroup.

Type: String

Length Constraints: Maximum length of 128.

Required: No

EventTimeFeatureName

The name of the feature that stores the EventTime of a Record in a FeatureGroup.

An EventTime is a point in time when a new event occurs that corresponds to the creation or update of a Record in a FeatureGroup. All Records in the FeatureGroup must have a corresponding EventTime.

An EventTime can be a String or Fractional.

  • Fractional: EventTime feature values must be a Unix timestamp in seconds.

  • String: EventTime feature values must be an ISO-8601 string in the format. The following formats are supported yyyy-MM-dd'T'HH:mm:ssZ and yyyy-MM-dd'T'HH:mm:ss.SSSZ where yyyy, MM, and dd represent the year, month, and day respectively and HH, mm, ss, and if applicable, SSS represent the hour, month, second and milliseconds respsectively. 'T' and Z are constants.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[a-zA-Z0-9]([-_]*[a-zA-Z0-9]){0,63}

Required: Yes

FeatureDefinitions

A list of Feature names and types. Name and Type is compulsory per Feature.

Valid feature FeatureTypes are Integral, Fractional and String.

FeatureNames cannot be any of the following: is_deleted, write_time, api_invocation_time

You can create up to 2,500 FeatureDefinitions per FeatureGroup.

Type: Array of FeatureDefinition objects

Array Members: Minimum number of 1 item. Maximum number of 2500 items.

Required: Yes

FeatureGroupName

The name of the FeatureGroup. The name must be unique within an AWS Region in an AWS account. The name:

  • Must start and end with an alphanumeric character.

  • Can only contain alphanumeric character and hyphens. Spaces are not allowed.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[a-zA-Z0-9](-*[a-zA-Z0-9]){0,63}

Required: Yes

OfflineStoreConfig

Use this to configure an OfflineFeatureStore. This parameter allows you to specify:

  • The Amazon Simple Storage Service (Amazon S3) location of an OfflineStore.

  • A configuration for an AWS Glue or AWS Hive data cataolgue.

  • An KMS encryption key to encrypt the Amazon S3 location used for OfflineStore.

To learn more about this parameter, see OfflineStoreConfig.

Type: OfflineStoreConfig object

Required: No

OnlineStoreConfig

You can turn the OnlineStore on or off by specifying True for the EnableOnlineStore flag in OnlineStoreConfig; the default value is False.

You can also include an AWS KMS key ID (KMSKeyId) for at-rest encryption of the OnlineStore.

Type: OnlineStoreConfig object

Required: No

RecordIdentifierFeatureName

The name of the Feature whose value uniquely identifies a Record defined in the FeatureStore. Only the latest record per identifier value will be stored in the OnlineStore. RecordIdentifierFeatureName must be one of feature definitions' names.

You use the RecordIdentifierFeatureName to access data in a FeatureStore.

This name:

  • Must start and end with an alphanumeric character.

  • Can only contains alphanumeric characters, hyphens, underscores. Spaces are not allowed.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: ^[a-zA-Z0-9]([-_]*[a-zA-Z0-9]){0,63}

Required: Yes

RoleArn

The Amazon Resource Name (ARN) of the IAM execution role used to persist data into the OfflineStore if an OfflineStoreConfig is provided.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: ^arn:aws[a-z\-]*:iam::\d{12}:role/?[a-zA-Z_0-9+=,.@\-_/]+$

Required: No

Tags

Tags used to identify Features in each FeatureGroup.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

Response Syntax

{ "FeatureGroupArn": "string" }

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.

FeatureGroupArn

The Amazon Resource Name (ARN) of the FeatureGroup. This is a unique identifier for the feature group.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:aws[a-z\-]*:sagemaker:[a-z0-9\-]*:[0-9]{12}:feature-group/.*
