@Stability(Stable) public static interface CfnCluster.ScalingConstraintsProperty extends software.amazon.jsii.JsiiSerializable
ScalingConstraints is a subproperty of the AutoScalingPolicy property type.

ScalingConstraints defines the upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activities triggered by automatic scaling rules will not cause an instance group to grow above or shrink below these limits.

Example: 

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 ScalingConstraintsProperty scalingConstraintsProperty = ScalingConstraintsProperty.builder()
         .maxCapacity(123)
         .minCapacity(123)
         .build();

  • Method Details

    • getMaxCapacity

      @Stability(Stable) @NotNull Number getMaxCapacity()
      The upper boundary of Amazon EC2 instances in an instance group beyond which scaling activities are not allowed to grow.

      Scale-out activities will not add instances beyond this boundary.

    • getMinCapacity

      @Stability(Stable) @NotNull Number getMinCapacity()
      The lower boundary of Amazon EC2 instances in an instance group below which scaling activities are not allowed to shrink.

      Scale-in activities will not terminate instances below this boundary.

    • builder

      @Stability(Stable) static CfnCluster.ScalingConstraintsProperty.Builder builder()
      Returns:
      a CfnCluster.ScalingConstraintsProperty.Builder of CfnCluster.ScalingConstraintsProperty
