<a name="API_OutputDataConfig"></a>

Provides information about how to store model training results (model artifacts).

 ** S3OutputPath **   <a name="sagemaker-Type-OutputDataConfig-S3OutputPath"></a>
Identifies the S3 path where you want SageMaker to store the model artifacts. For example, `s3://bucket-name/key-name-prefix`.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 1024.  
Pattern: `(https|s3)://([^/]+)/?(.*)`   
Required: Yes

 ** CompressionType **   <a name="sagemaker-Type-OutputDataConfig-CompressionType"></a>
The model output compression type. Select `None` to output an uncompressed model, recommended for large model outputs. Defaults to gzip.  
Type: String  
Valid Values: `GZIP | NONE`   
Required: No

 ** KmsKeyId **   <a name="sagemaker-Type-OutputDataConfig-KmsKeyId"></a>
The AWS Key Management Service (AWS KMS) key that SageMaker uses to encrypt the model artifacts at rest using Amazon S3 server-side encryption. The `KmsKeyId` can be any 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"` 
+ // KMS Key Alias

   `"alias/ExampleAlias"` 
+ // Amazon Resource Name (ARN) of a KMS Key Alias

   `"arn:aws:kms:us-west-2:111122223333:alias/ExampleAlias"` 
If you use a KMS key ID or an alias of your KMS key, the SageMaker execution role must include permissions to call `kms:Encrypt`. If you don't provide a KMS key ID, SageMaker uses the default KMS key for Amazon S3 for your role's account. For more information, see [KMS-Managed Encryption Keys](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingKMSEncryption.html) in the *Amazon Simple Storage Service Developer Guide*. If the output data is stored in Amazon S3 Express One Zone, it is encrypted with server-side encryption with Amazon S3 managed keys (SSE-S3). KMS key is not supported for Amazon S3 Express One Zone  
The KMS key policy must grant permission to the IAM role that you specify in your `CreateTrainingJob`, `CreateTransformJob`, or `CreateHyperParameterTuningJob` requests. For more information, see [Using Key Policies in AWS KMS](https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html) in the * AWS Key Management Service Developer Guide*.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 2048.  
Pattern: `[a-zA-Z0-9:/_-]*`   
Required: No
