# AWS::SageMaker::Endpoint CapacitySize
<a name="aws-properties-sagemaker-endpoint-capacitysize"></a>

Specifies the type and size of the endpoint capacity to activate for a blue/green deployment, a rolling deployment, or a rollback strategy. You can specify your batches as either instance count or 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` to 100%, then SageMaker uses a blue/green rollback strategy and rolls all traffic back to the blue fleet.

## Syntax

}
```

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