Properties

createdOn → DateTime?
A timestamp. The time and date that this machine learning transform was created.
final
description → String?
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.
final
evaluationMetrics → EvaluationMetrics?
An EvaluationMetrics object. Evaluation metrics provide an estimate of the quality of your machine learning transform.
final
glueVersion → String?
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.
final
hashCode → int
The hash code for this object.
no setterinherited
inputRecordTables → List<GlueTable>?
A list of AWS Glue table definitions used by the transform.
final
labelCount → int?
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.
final
lastModifiedOn → DateTime?
A timestamp. The last point in time when this machine learning transform was modified.
final
maxCapacity → 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.
final
maxRetries → int?
The maximum number of times to retry after an MLTaskRun of the machine learning transform fails.
final
name → String?
A user-defined name for the machine learning transform. Names are not guaranteed unique and can be changed at any time.
final
numberOfWorkers → int?
The number of workers of a defined workerType that are allocated when a task of the transform runs.
final
parameters → 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).
final
role → String?
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.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
schema → List<SchemaColumn>?
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.
final
status → TransformStatusType?
The current status of the machine learning transform.
final
timeout → int?
The timeout in minutes of the machine learning transform.
final
transformEncryption → 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.
final
transformId → String?
The unique transform ID that is generated for the machine learning transform. The ID is guaranteed to be unique and does not change.
final
workerType → 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.
final

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

Operators

operator ==(Object other) → bool
The equality operator.
