 ** S3DataType **   <a name="sagemaker-Type-TransformS3DataSource-S3DataType"></a>
If you choose `S3Prefix`, `S3Uri` identifies a key name prefix. Amazon SageMaker uses all objects with the specified key name prefix for batch transform.   
If you choose `ManifestFile`, `S3Uri` identifies an object that is a manifest file containing a list of object keys that you want Amazon SageMaker to use for batch transform.   
The following values are compatible: `ManifestFile`, `S3Prefix`   
The following value is not compatible: `AugmentedManifestFile`   
Type: String  
Valid Values: `ManifestFile | S3Prefix | AugmentedManifestFile | Converse`   
Required: Yes

 ** S3Uri **   <a name="sagemaker-Type-TransformS3DataSource-S3Uri"></a>
Depending on the value specified for the `S3DataType`, identifies either a key name prefix or a manifest. For example:  
+  A key name prefix might look like this: `s3://bucketname/exampleprefix/`. 
+  A manifest might look like this: `s3://bucketname/example.manifest` 

   The manifest is an S3 object which is a JSON file with the following format: 

   `[ {"prefix": "s3://customer_bucket/some/prefix/"},` 

   `"relative/path/to/custdata-1",` 

   `"relative/path/custdata-2",` 

   `...` 

   `"relative/path/custdata-N"` 

   `]` 

   The preceding JSON matches the following `S3Uris`: 

   `s3://customer_bucket/some/prefix/relative/path/to/custdata-1` 

   `s3://customer_bucket/some/prefix/relative/path/custdata-2` 

   `...` 

   `s3://customer_bucket/some/prefix/relative/path/custdata-N` 

   The complete set of `S3Uris` in this manifest constitutes the input data for the channel for this datasource. The object that each `S3Uris` points to must be readable by the IAM role that Amazon SageMaker uses to perform tasks on your behalf.
Type: String
