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 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 thanStandard
, theMaxCapacity
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
