 ** MetricSpecifications **   <a name="autoscaling-Type-PredictiveScalingPolicyConfiguration-MetricSpecifications"></a>
 This structure includes the metrics and target utilization to use for predictive scaling.   
This is an array, but we currently only support a single metric specification. That is, you can specify a target value and a single metric pair, or a target value and one scaling metric and one load metric.  
Type: Array of [PredictiveScalingMetricSpecification](API_PredictiveScalingMetricSpecification.md) objects  
Required: Yes

 ** MaxCapacityBreachBehavior **   <a name="autoscaling-Type-PredictiveScalingPolicyConfiguration-MaxCapacityBreachBehavior"></a>
 Defines the behavior that should be applied if the forecast capacity approaches or exceeds the maximum capacity. Defaults to `HonorMaxCapacity` if not specified.   
Type: String  
Valid Values: `HonorMaxCapacity | IncreaseMaxCapacity`   
Required: No

 ** MaxCapacityBuffer **   <a name="autoscaling-Type-PredictiveScalingPolicyConfiguration-MaxCapacityBuffer"></a>
 The size of the capacity buffer to use when the forecast capacity is close to or exceeds the maximum capacity. The value is specified as a percentage relative to the forecast capacity. For example, if the buffer is 10, this means a 10 percent buffer, such that if the forecast capacity is 50, and the maximum capacity is 40, then the effective maximum capacity is 55.   
Required if the `MaxCapacityBreachBehavior` property is set to `IncreaseMaxCapacity`, and cannot be used otherwise.  
Type: Integer  
Valid Range: Minimum value of 0. Maximum value of 100.  
Required: No

 ** Mode **   <a name="autoscaling-Type-PredictiveScalingPolicyConfiguration-Mode"></a>
 The predictive scaling mode. Defaults to `ForecastOnly` if not specified.   
Type: String  
Valid Values: `ForecastOnly | ForecastAndScale`   
Required: No

 ** SchedulingBufferTime **   <a name="autoscaling-Type-PredictiveScalingPolicyConfiguration-SchedulingBufferTime"></a>
 The amount of time, in seconds, that the start time can be advanced.   
The value must be less than the forecast interval duration of 3600 seconds (60 minutes). Defaults to 300 seconds if not specified.   
Type: Integer  
Valid Range: Minimum value of 0. Maximum value of 3600.  
Required: No
