# AWS::SageMaker::EndpointConfig AsyncInferenceConfig
<a name="aws-properties-sagemaker-endpointconfig-asyncinferenceconfig"></a>

Specifies configuration for how an endpoint performs asynchronous inference.

## Syntax
<a name="aws-properties-sagemaker-endpointconfig-asyncinferenceconfig-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-sagemaker-endpointconfig-asyncinferenceconfig-syntax.json"></a>

```
{
  "[ClientConfig](#cfn-sagemaker-endpointconfig-asyncinferenceconfig-clientconfig)" : AsyncInferenceClientConfig,
  "[OutputConfig](#cfn-sagemaker-endpointconfig-asyncinferenceconfig-outputconfig)" : AsyncInferenceOutputConfig
}
```

### YAML
<a name="aws-properties-sagemaker-endpointconfig-asyncinferenceconfig-syntax.yaml"></a>

```
  [ClientConfig](#cfn-sagemaker-endpointconfig-asyncinferenceconfig-clientconfig): 
    AsyncInferenceClientConfig
  [OutputConfig](#cfn-sagemaker-endpointconfig-asyncinferenceconfig-outputconfig): 
    AsyncInferenceOutputConfig
```

## Properties
<a name="aws-properties-sagemaker-endpointconfig-asyncinferenceconfig-properties"></a>

`ClientConfig`  <a name="cfn-sagemaker-endpointconfig-asyncinferenceconfig-clientconfig"></a>
Configures the behavior of the client used by SageMaker to interact with the model container during asynchronous inference.
