create-ml-transform

Description

Creates an AWS Glue machine learning transform. This operation creates the transform and all the necessary parameters to train it.

Call this operation as the first step in the process of using a machine learning transform (such as the FindMatches transform) for deduplicating data. You can provide an optional Description , in addition to the parameters that you want to use for your algorithm.

You must also specify certain parameters for the tasks that AWS Glue runs on your behalf as part of learning from your data and creating a high-quality machine learning transform. These parameters include Role , and optionally, AllocatedCapacity , Timeout , and MaxRetries . For more information, see Jobs .

See 'aws help' for descriptions of global parameters.

Options

--name (string)

The unique name that you give the transform when you create it.

--description (string)

A description of the machine learning transform that is being defined. The default is an empty string.

--input-record-tables (list)

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

Shorthand Syntax:

DatabaseName=string,TableName=string,CatalogId=string,ConnectionName=string ...

JSON Syntax:

[
  {
    "DatabaseName": "string",
    "TableName": "string",
    "CatalogId": "string",
    "ConnectionName": "string"
  }
  ...
]

--parameters (structure)

The algorithmic parameters that are specific to the transform type used. Conditionally dependent on the transform type.

Shorthand Syntax:

TransformType=string,FindMatchesParameters={PrimaryKeyColumnName=string,PrecisionRecallTradeoff=double,AccuracyCostTradeoff=double,EnforceProvidedLabels=boolean}

JSON Syntax:

{
  "TransformType": "FIND_MATCHES",
  "FindMatchesParameters": {
    "PrimaryKeyColumnName": "string",
    "PrecisionRecallTradeoff": double,
    "AccuracyCostTradeoff": double,
    "EnforceProvidedLabels": true|false
  }
}

--role (string)

The name or Amazon Resource Name (ARN) of the IAM role with the required permissions. Ensure that this role has permission to your Amazon Simple Storage Service (Amazon S3) sources, targets, temporary directory, scripts, and any libraries that are used by the task run for this transform.

--max-capacity (double)

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.

--worker-type (string)

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.

Possible values:

  • Standard
  • G.1X
  • G.2X

--number-of-workers (integer)

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

--timeout (integer)

The timeout of the 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).

--max-retries (integer)

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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

TransformId -> (string)

A unique identifier that is generated for the transform.
