# AWS::SageMaker::InferenceComponent InferenceComponentCapacitySize
<a name="aws-properties-sagemaker-inferencecomponent-inferencecomponentcapacitysize"></a>

Specifies the type and size of the endpoint capacity to activate for a rolling deployment or a rollback strategy. You can specify your batches as either of the following:
+ A count of inference component copies 
+ The overall percentage or your fleet 

For a rollback strategy, if you don't specify the fields in this object, or if you set the `Value` parameter to 100%, then SageMaker AI uses a blue/green rollback strategy and rolls all traffic back to the blue fleet.

## Syntax
<a name="aws-properties-sagemaker-inferencecomponent-inferencecomponentcapacitysize-syntax"></a>

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

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

```
{
  "[Type](#cfn-sagemaker-inferencecomponent-inferencecomponentcapacitysize-type)" : String,
  "[Value](#cfn-sagemaker-inferencecomponent-inferencecomponentcapacitysize-value)" : Integer
}
```

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

```
  [Type](#cfn-sagemaker-inferencecomponent-inferencecomponentcapacitysize-type): String
  [Value](#cfn-sagemaker-inferencecomponent-inferencecomponentcapacitysize-value): Integer
```

## Properties
<a name="aws-properties-sagemaker-inferencecomponent-inferencecomponentcapacitysize-properties"></a>

`Type`  <a name="cfn-sagemaker-inferencecomponent-inferencecomponentcapacitysize-type"></a>
Specifies the endpoint capacity type.    
COPY\$1COUNT  
The endpoint activates based on the number of inference component copies.  
CAPACITY\$1PERCENT  
The endpoint activates based on the specified percentage of capacity.
