MLTransform
¶
Source code in docs_src/capo_glue/types/ml_transform.py
created_on
instance-attribute
¶
created_on: NotRequired[Timestamp]
A timestamp. The time and date that this machine learning transform was created.
description
instance-attribute
¶
description: NotRequired[DescriptionString]
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.
evaluation_metrics
instance-attribute
¶
evaluation_metrics: NotRequired[EvaluationMetrics]
An EvaluationMetrics object. Evaluation metrics provide an estimate of the quality of your machine learning transform.
glue_version
instance-attribute
¶
glue_version: NotRequired[GlueVersionString]
This value determines which version of 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 Glue Versions in the developer guide.
input_record_tables
instance-attribute
¶
input_record_tables: NotRequired[GlueTables]
A list of Glue table definitions used by the transform.
label_count
instance-attribute
¶
label_count: LabelCount
A count identifier for the labeling files generated by Glue for this transform. As you create a better transform, you can iteratively download, label, and upload the labeling file.
last_modified_on
instance-attribute
¶
last_modified_on: NotRequired[Timestamp]
A timestamp. The last point in time when this machine learning transform was modified.
max_capacity
instance-attribute
¶
max_capacity: NotRequired[NullableDouble]
The number of 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 Glue pricing page.
MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.
-
If either
NumberOfWorkersorWorkerTypeis set, thenMaxCapacitycannot be set. -
If
MaxCapacityis set then neitherNumberOfWorkersorWorkerTypecan be set. -
If
WorkerTypeis set, thenNumberOfWorkersis required (and vice versa). -
MaxCapacityandNumberOfWorkersmust both be at least 1.
When the WorkerType field is set to a value other than Standard, the MaxCapacity field is set automatically and becomes read-only.
max_retries
instance-attribute
¶
max_retries: NotRequired[NullableInteger]
The maximum number of times to retry after an MLTaskRun of the machine learning transform fails.
name
instance-attribute
¶
name: NotRequired[NameString]
A user-defined name for the machine learning transform. Names are not guaranteed unique and can be changed at any time.
number_of_workers
instance-attribute
¶
number_of_workers: NotRequired[NullableInteger]
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).
parameters
instance-attribute
¶
parameters: NotRequired[TransformParameters]
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).
role
instance-attribute
¶
role: NotRequired[RoleString]
The name or Amazon Resource Name (ARN) of the IAM role with the required permissions. The required permissions include both Glue service role permissions to Glue resources, and Amazon S3 permissions required by the transform.
-
This role needs Glue service role permissions to allow access to resources in Glue. See Attach a Policy to IAM Users That Access Glue.
-
This role needs permission to your Amazon Simple Storage Service (Amazon S3) sources, targets, temporary directory, scripts, and any libraries used by the task run for this transform.
schema
instance-attribute
¶
schema: NotRequired[TransformSchema]
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.
status
instance-attribute
¶
status: NotRequired[TransformStatusType]
The current status of the machine learning transform.
timeout
instance-attribute
¶
timeout: NotRequired[Timeout]
The timeout in minutes of the machine learning transform.
transform_encryption
instance-attribute
¶
transform_encryption: NotRequired[TransformEncryption]
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.
transform_id
instance-attribute
¶
transform_id: NotRequired[HashString]
The unique transform ID that is generated for the machine learning transform. The ID is guaranteed to be unique and does not change.
worker_type
instance-attribute
¶
worker_type: NotRequired[WorkerType]
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.
-
For the
Standardworker type, each worker provides 4 vCPU, 16 GB of memory and a 50GB disk, and 2 executors per worker. -
For the
G.1Xworker type, each worker provides 4 vCPU, 16 GB of memory and a 64GB disk, and 1 executor per worker. -
For the
G.2Xworker type, each worker provides 8 vCPU, 32 GB of memory and a 128GB disk, and 1 executor per worker.
MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.
-
If either
NumberOfWorkersorWorkerTypeis set, thenMaxCapacitycannot be set. -
If
MaxCapacityis set then neitherNumberOfWorkersorWorkerTypecan be set. -
If
WorkerTypeis set, thenNumberOfWorkersis required (and vice versa). -
MaxCapacityandNumberOfWorkersmust both be at least 1.
