      • transformId

        public final String transformId()

        The unique transform ID that is generated for the machine learning transform. The ID is guaranteed to be unique and does not change.

        Returns:
        The unique transform ID that is generated for the machine learning transform. The ID is guaranteed to be unique and does not change.
      • name

        public final String name()

        A user-defined name for the machine learning transform. Names are not guaranteed unique and can be changed at any time.

        Returns:
        A user-defined name for the machine learning transform. Names are not guaranteed unique and can be changed at any time.
      • description

        public final String description()

        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.

        Returns:
        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.
      • statusAsString

        public final String statusAsString()

        The current status of the machine learning transform.

        If the service returns an enum value that is not available in the current SDK version, status will return TransformStatusType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from statusAsString().

        Returns:
        The current status of the machine learning transform.

        TransformStatusType
      • createdOn

        public final Instant createdOn()

        A timestamp. The time and date that this machine learning transform was created.

        Returns:
        A timestamp. The time and date that this machine learning transform was created.
      • lastModifiedOn

        public final Instant lastModifiedOn()

        A timestamp. The last point in time when this machine learning transform was modified.

        Returns:
        A timestamp. The last point in time when this machine learning transform was modified.
      • hasInputRecordTables

        public final boolean hasInputRecordTables()
        For responses, this returns true if the service returned a value for the InputRecordTables property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • inputRecordTables

        public final List<GlueTable> inputRecordTables()

        A list of Glue table definitions used by the transform.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInputRecordTables() method.

        Returns:
        A list of Glue table definitions used by the transform.
      • parameters

        public final TransformParameters parameters()

        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).

        Returns:
        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).
      • evaluationMetrics

        public final EvaluationMetrics evaluationMetrics()

        An EvaluationMetrics object. Evaluation metrics provide an estimate of the quality of your machine learning transform.

        Returns:
        An EvaluationMetrics object. Evaluation metrics provide an estimate of the quality of your machine learning transform.
      • labelCount

        public final Integer 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.

        Returns:
        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.
      • hasSchema

        public final boolean hasSchema()
        For responses, this returns true if the service returned a value for the Schema property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • schema

        public final List<SchemaColumn> schema()

        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.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSchema() method.

        Returns:
        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.
      • role

        public final String role()

        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.

        Returns:
        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.

      • glueVersion

        public final String glueVersion()

      • maxCapacity

        public final Double maxCapacity()

        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.

        MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.
