ComputeLimits | Amazon.ElasticMapReduce.Model.ComputeLimits |
Gets and sets the property ComputeLimits. The Amazon EC2 unit limits for a managed scaling policy. The managed scaling activity of a cluster is not allowed to go above or below these limits. The limit only applies to the core and task nodes. The master node cannot be scaled after initial configuration. |

ScalingStrategy | Amazon.ElasticMapReduce.ScalingStrategy |
Gets and sets the property ScalingStrategy. Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT. |
|
|
UtilizationPerformanceIndex | System.Int32 |
Gets and sets the property UtilizationPerformanceIndex. An integer value that represents an advanced scaling strategy. Setting a higher value optimizes for performance. Setting a lower value optimizes for resource conservation. Setting the value to 50 balances performance and resource conservation. Possible values are 1, 25, 50, 75, and 100. |
