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 Details

    • 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.

    • toBuilder

      public ManagedScalingPolicy.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<ManagedScalingPolicy.Builder,ManagedScalingPolicy>
      Returns:
      a builder for type T

    • builder

      public static ManagedScalingPolicy.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ManagedScalingPolicy.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
