startDominantLanguageDetectionJob method

Future<StartDominantLanguageDetectionJobResponse> startDominantLanguageDetectionJob({ required String dataAccessRoleArn, required InputDataConfig inputDataConfig, required OutputDataConfig outputDataConfig, String? clientRequestToken, String? jobName, List<Tag>? tags, String? volumeKmsKeyId, VpcConfig? vpcConfig, })

Starts an asynchronous dominant language detection job for a collection of documents. Use the operation to track the status of a job.

May throw InternalServerException. May throw InvalidRequestException. May throw KmsKeyValidationException. May throw ResourceInUseException. May throw TooManyRequestsException. May throw TooManyTagsException.

Parameter dataAccessRoleArn : The Amazon Resource Name (ARN) of the IAM role that grants Amazon Comprehend read access to your input data. For more information, see Role-based permissions.

Parameter inputDataConfig : Specifies the format and location of the input data for the job.

Parameter outputDataConfig : Specifies where to send the output files.

Parameter clientRequestToken : A unique identifier for the request. If you do not set the client request token, Amazon Comprehend generates one.

Parameter jobName : An identifier for the job.

Parameter tags : Tags to associate with the dominant language detection job. A tag is a key-value pair that adds metadata to a resource used by Amazon Comprehend. For example, a tag with "Sales" as the key might be added to a resource to indicate its use by the sales department.

Parameter volumeKmsKeyId : ID for the Amazon Web Services Key Management Service (KMS) key that Amazon Comprehend uses to encrypt data on the storage volume attached to the ML compute instance(s) that process the analysis job. The VolumeKmsKeyId can be either of the following formats:

• KMS Key ID: "1234abcd-12ab-34cd-56ef-1234567890ab"
• Amazon Resource Name (ARN) of a KMS Key: "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab"

Parameter vpcConfig : Configuration parameters for an optional private Virtual Private Cloud (VPC) containing the resources you are using for your dominant language detection job. For more information, see Amazon VPC.
