Explanation in Terraform Registry
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 for more information.
AWS::EMR::Cluster ManagedScalingPolicy (CloudFormation)
The Cluster ManagedScalingPolicy in EMR can be configured in CloudFormation with the resource name AWS::EMR::Cluster ManagedScalingPolicy. The following sections describe how to use the resource and its parameters.
Example Usage from GitHub
An example could not be found in GitHub.
Parameters
ComputeLimits
The 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.
Required: No
Type: ComputeLimits
Update requires: No interruption
Explanation in CloudFormation Registry
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.
