 ** TransformInput **   <a name="sagemaker-Type-TransformJobDefinition-TransformInput"></a>
A description of the input source and the way the transform job consumes it.  
Type: [TransformInput](API_TransformInput.md) object  
Required: Yes

 ** TransformOutput **   <a name="sagemaker-Type-TransformJobDefinition-TransformOutput"></a>
Identifies the Amazon S3 location where you want Amazon SageMaker to save the results from the transform job.  
Type: [TransformOutput](API_TransformOutput.md) object  
Required: Yes

 ** TransformResources **   <a name="sagemaker-Type-TransformJobDefinition-TransformResources"></a>
Identifies the ML compute instances for the transform job.  
Type: [TransformResources](API_TransformResources.md) object  
Required: Yes

 ** BatchStrategy **   <a name="sagemaker-Type-TransformJobDefinition-BatchStrategy"></a>
A string that determines the number of records included in a single mini-batch.  
 `SingleRecord` means only one record is used per mini-batch. `MultiRecord` means a mini-batch is set to contain as many records that can fit within the `MaxPayloadInMB` limit.  
Type: String  
Valid Values: `MultiRecord | SingleRecord`   
Required: No

 ** Environment **   <a name="sagemaker-Type-TransformJobDefinition-Environment"></a>
The environment variables to set in the Docker container. We support up to 16 key and values entries in the map.  
Type: String to string map  
Map Entries: Minimum number of 0 items. Maximum number of 16 items.  
Key Length Constraints: Minimum length of 0. Maximum length of 1024.  
Key Pattern: `[a-zA-Z_][a-zA-Z0-9_]{0,1023}`   
Value Length Constraints: Minimum length of 0. Maximum length of 10240.  
Value Pattern: `[\S\s]*`   
Required: No

 ** MaxConcurrentTransforms **   <a name="sagemaker-Type-TransformJobDefinition-MaxConcurrentTransforms"></a>
The maximum number of parallel requests that can be sent to each instance in a transform job. The default value is 1.  
Type: Integer  
Valid Range: Minimum value of 0.  
Required: No

 ** MaxPayloadInMB **   <a name="sagemaker-Type-TransformJobDefinition-MaxPayloadInMB"></a>
The maximum payload size allowed, in MB. A payload is the data portion of a record (without metadata).  
Type: Integer  
Valid Range: Minimum value of 0.  
Required: No
