UpdateMLTransform - AWS Glue
このページはお客様の言語に翻訳されていません。 翻訳のリクエスト

UpdateMLTransform

Updates an existing machine learning transform. Call this operation to tune the algorithm parameters to achieve better results.

After calling this operation, you can call the StartMLEvaluationTaskRun operation to assess how well your new parameters achieved your goals (such as improving the quality of your machine learning transform, or making it more cost-effective).

Request Syntax

{ "Description": "string", "GlueVersion": "string", "MaxCapacity": number, "MaxRetries": number, "Name": "string", "NumberOfWorkers": number, "Parameters": { "FindMatchesParameters": { "AccuracyCostTradeoff": number, "EnforceProvidedLabels": boolean, "PrecisionRecallTradeoff": number, "PrimaryKeyColumnName": "string" }, "TransformType": "string" }, "Role": "string", "Timeout": number, "TransformId": "string", "WorkerType": "string" }

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 description of the transform. The default is an empty string.

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

GlueVersion

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

MaxCapacity

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.

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

MaxRetries

The maximum number of times to retry a task for this transform after a task run fails.

Type: Integer

Required: No

Name

The unique name that you gave the transform when you created it.

Type: String

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

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

Required: No

NumberOfWorkers

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

Type: Integer

Required: No

Parameters

The configuration parameters that are specific to the transform type (algorithm) used. Conditionally dependent on the transform type.

Type: TransformParameters object

Required: No

Role

The name or Amazon Resource Name (ARN) of the IAM role with the required permissions.

Type: String

Required: No

Timeout

The timeout for a task run for this transform in minutes. This is the maximum time that a task run for this transform can consume resources before it is terminated and enters TIMEOUT status. The default is 2,880 minutes (48 hours).

Type: Integer

Valid Range: Minimum value of 1.

Required: No

TransformId

A unique identifier that was generated when the transform was created.

Type: String

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

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

Required: Yes

WorkerType

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

  • For the Standard worker type, each worker provides 4 vCPU, 16 GB of memory and a 50GB disk, and 2 executors per worker.

  • For the G.1X worker type, each worker provides 4 vCPU, 16 GB of memory and a 64GB disk, and 1 executor per worker.

  • For the G.2X worker type, each worker provides 8 vCPU, 32 GB of memory and a 128GB disk, and 1 executor per worker.

Type: String

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

Required: No

Response Syntax

{ "TransformId": "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.

TransformId

The unique identifier for the transform that was updated.

Type: String

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

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

Errors

HTTP Status Code: 400

EntityNotFoundException

A specified entity does not exist

HTTP Status Code: 400

InternalServiceException

An internal service error occurred.

HTTP Status Code: 500

InvalidInputException

The input provided was not valid.

HTTP Status Code: 400

OperationTimeoutException

The operation timed out.

HTTP Status Code: 400
