com.pulumi.resources.Resource

com.pulumi.resources.CustomResource

com.pulumi.aws.emr.ManagedScalingPolicy

public class ManagedScalingPolicy
extends com.pulumi.resources.CustomResource

Provides a Managed Scaling policy for EMR Cluster. With Amazon EMR versions 5.30.0 and later (except for Amazon EMR 6.0.0), you can enable EMR managed scaling to automatically increase or decrease the number of instances or units in your cluster based on workload. See [Using EMR Managed Scaling in Amazon EMR](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-managed-scaling.html) for more information. ## Example Usage

## Import Using `pulumi import`, import EMR Managed Scaling Policies using the EMR Cluster identifier. For example: ```sh $ pulumi import aws:emr/managedScalingPolicy:ManagedScalingPolicy example j-123456ABCDEF ```

Constructor Detail

ManagedScalingPolicy

public ManagedScalingPolicy(java.lang.String name)

Parameters:

name - The _unique_ name of the resulting resource.

ManagedScalingPolicy

public ManagedScalingPolicy(java.lang.String name,
                            ManagedScalingPolicyArgs args)

Parameters:

name - The _unique_ name of the resulting resource.

args - The arguments to use to populate this resource's properties.

ManagedScalingPolicy

public ManagedScalingPolicy(java.lang.String name,
                            ManagedScalingPolicyArgs args,
                            @Nullable
                            com.pulumi.resources.CustomResourceOptions options)

Parameters:

name - The _unique_ name of the resulting resource.

args - The arguments to use to populate this resource's properties.

options - A bag of options that control this resource's behavior.

Method Detail

clusterId

public com.pulumi.core.Output<java.lang.String> clusterId()

Returns:

ID of the EMR cluster

computeLimits

public com.pulumi.core.Output<java.util.List<ManagedScalingPolicyComputeLimit>> computeLimits()

Returns:

Configuration block with compute limit settings. Described below.

region

public com.pulumi.core.Output<java.lang.String> region()

Returns:

Region where this resource will be [managed](https://docs.aws.amazon.com/general/latest/gr/rande.html#regional-endpoints). Defaults to the Region set in the provider configuration.

scalingStrategy

public com.pulumi.core.Output<java.util.Optional<java.lang.String>> scalingStrategy()

Returns:

Specifies the scaling strategy. When set to `ADVANCED`, the `utilizationPerformanceIndex` argument can be used to configure an advanced scaling strategy. An advanced scaling strategy requires Amazon EMR on EC2 version 7.0 or later. Valid values: `ADVANCED`, `DEFAULT`.

utilizationPerformanceIndex

public com.pulumi.core.Output<java.util.Optional<java.lang.Integer>> utilizationPerformanceIndex()

Returns:

Integer value that represents the advanced scaling strategy. Higher values optimize for performance, while lower values optimize for resource conservation. A value of `50` provides a balance between performance and resource conservation. See [the AWS documentation](https://docs.aws.amazon.com/emr/latest/ManagementGuide/managed-scaling-allocation-strategy-optimized.html#managed-scaling-allocation-strategy-optimized-getting-started) for more details. Required when `scalingStrategy` is set to `ADVANCED`. Valid values: `1`, `25`, `50`, `75`, `100`.

get

public static ManagedScalingPolicy get(java.lang.String name,
                                       com.pulumi.core.Output<java.lang.String> id,
                                       @Nullable
                                       ManagedScalingPolicyState state,
                                       @Nullable
                                       com.pulumi.resources.CustomResourceOptions options)

Get an existing Host resource's state with the given name, ID, and optional extra properties used to qualify the lookup.

Parameters:

name - The _unique_ name of the resulting resource.

id - The _unique_ provider ID of the resource to lookup.

state -

options - Optional settings to control the behavior of the CustomResource.
