MLTransform

A timestamp. The time and date that this machine learning transform was created.

Type: Timestamp

Required: No

A user-defined, long-form description text for the machine learning transform. Descriptions are not guaranteed to be unique and can be changed at any time.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 2048.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\r\n\t]*

Required: No

An EvaluationMetrics object. Evaluation metrics provide an estimate of the quality of your machine learning transform.

Type: EvaluationMetrics object

Required: No

This value determines which version of AWS Glue this machine learning transform is compatible with. Glue 1.0 is recommended for most customers. If the value is not set, the Glue compatibility defaults to Glue 0.9. For more information, see AWS Glue Versions in the developer guide.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: ^\w+\.\w+$

Required: No

A list of AWS Glue table definitions used by the transform.

Type: Array of GlueTable objects

Array Members: Minimum number of 0 items. Maximum number of 10 items.

Required: No

A count identifier for the labeling files generated by AWS Glue for this transform. As you create a better transform, you can iteratively download, label, and upload the labeling file.

Type: Integer

Required: No

A timestamp. The last point in time when this machine learning transform was modified.

Type: Timestamp

Required: No

The number of AWS Glue data processing units (DPUs) that are allocated to task runs for this transform. You can allocate from 2 to 100 DPUs; the default is 10. A DPU is a relative measure of processing power that consists of 4 vCPUs of compute capacity and 16 GB of memory. For more information, see the AWS Glue pricing page.

MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.

When the WorkerType field is set to a value other than Standard, the MaxCapacity field is set automatically and becomes read-only.

Type: Double

Required: No

The maximum number of times to retry after an MLTaskRun of the machine learning transform fails.

Type: Integer

Required: No

A user-defined name for the machine learning transform. Names are not guaranteed unique and can be changed at any time.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*

Required: No

The number of workers of a defined workerType that are allocated when a task of the transform runs.

If WorkerType is set, then NumberOfWorkers is required (and vice versa).

Type: Integer

Required: No

A TransformParameters object. You can use parameters to tune (customize) the behavior of the machine learning transform by specifying what data it learns from and your preference on various tradeoffs (such as precious vs. recall, or accuracy vs. cost).

Type: TransformParameters object

Required: No

The name or Amazon Resource Name (ARN) of the IAM role with the required permissions. The required permissions include both AWS Glue service role permissions to AWS Glue resources, and Amazon S3 permissions required by the transform.

Type: String

Required: No

A map of key-value pairs representing the columns and data types that this transform can run against. Has an upper bound of 100 columns.

Type: Array of SchemaColumn objects

Array Members: Maximum number of 100 items.

Required: No

The current status of the machine learning transform.

Type: String

Valid Values: NOT_READY | READY | DELETING

Required: No

The timeout in minutes of the machine learning transform.

Type: Integer

Valid Range: Minimum value of 1.

Required: No

The encryption-at-rest settings of the transform that apply to accessing user data. Machine learning transforms can access user data encrypted in Amazon S3 using KMS.

Type: TransformEncryption object

Required: No

The unique transform ID that is generated for the machine learning transform. The ID is guaranteed to be unique and does not change.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*

Required: No

The type of predefined worker that is allocated when a task of this transform runs. Accepts a value of Standard, G.1X, or G.2X.

MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.

Type: String

Valid Values: Standard | G.1X | G.2X | G.025X | G.4X | G.8X | Z.2X

Required: No
