Overview

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.

#compute_limits ⇒ Types::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:

#scaling_strategy ⇒ String

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

Returns:

end

#utilization_performance_index ⇒ Integer

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:

  • (Integer)
