Class ManagedScalingPolicy

java.lang.Object

software.amazon.awssdk.services.emr.model.ManagedScalingPolicy

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<ManagedScalingPolicy.Builder,ManagedScalingPolicy>

@Generated("software.amazon.awssdk:codegen")
public final class ManagedScalingPolicy
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<ManagedScalingPolicy.Builder,ManagedScalingPolicy>

Managed scaling policy for an Amazon EMR cluster. The policy specifies the limits for resources that can be added or terminated from a cluster. The policy only applies to the core and task nodes. The master node cannot be scaled after initial configuration.

Method Detail

computeLimits

public final ComputeLimits 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.

Returns:

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.

utilizationPerformanceIndex

public final Integer 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.

Returns:

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.

scalingStrategy

public final ScalingStrategy scalingStrategy()

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.

If the service returns an enum value that is not available in the current SDK version, scalingStrategy will return ScalingStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from scalingStrategyAsString().

Returns:

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.

scalingStrategyAsString

public final String scalingStrategyAsString()

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.

If the service returns an enum value that is not available in the current SDK version, scalingStrategy will return ScalingStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from scalingStrategyAsString().

Returns:

Determines whether a custom scaling utilization performance index can be set. Possible values include ADVANCED or DEFAULT.
