Instance Attribute Details

#graceful_decommission_timeout ⇒ String

Required. Timeout for Spark graceful decommissioning of spark workers. Specifies the duration to wait for spark worker to complete spark decomissioning tasks before forcefully removing workers. Only applicable to downscaling operations.Bounds: 0s, 1d. Corresponds to the JSON property gracefulDecommissionTimeout

Returns:

  • (String)

end

#scale_down_factor ⇒ Float

Required. Fraction of required executors to remove from Spark Serverless clusters. A scale-down factor of 1.0 will result in scaling down so that there are no more executors for the Spark Job.(more aggressive scaling). A scale- down factor closer to 0 will result in a smaller magnitude of scaling donw ( less aggressive scaling).Bounds: 0.0, 1.0. Corresponds to the JSON property scaleDownFactor

Returns:

  • (Float)

  @scale_down_factor
end

#scale_down_min_worker_fraction ⇒ Float

Optional. Minimum scale-down threshold as a fraction of total cluster size before scaling occurs. For example, in a 20-worker cluster, a threshold of 0.1 means the autoscaler must recommend at least a 2 worker scale-down for the cluster to scale. A threshold of 0 means the autoscaler will scale down on any recommended change.Bounds: 0.0, 1.0. Default: 0.0. Corresponds to the JSON property scaleDownMinWorkerFraction

Returns:

  • (Float)

end

#scale_up_factor ⇒ Float

Required. Fraction of required workers to add to Spark Standalone clusters. A scale-up factor of 1.0 will result in scaling up so that there are no more required workers for the Spark Job (more aggressive scaling). A scale-up factor closer to 0 will result in a smaller magnitude of scaling up (less aggressive scaling).Bounds: 0.0, 1.0. Corresponds to the JSON property scaleUpFactor

Returns:

  • (Float)

#scale_up_min_worker_fraction ⇒ Float

Optional. Minimum scale-up threshold as a fraction of total cluster size before scaling occurs. For example, in a 20-worker cluster, a threshold of 0.1 means the autoscaler must recommend at least a 2-worker scale-up for the cluster to scale. A threshold of 0 means the autoscaler will scale up on any recommended change.Bounds: 0.0, 1.0. Default: 0.0. Corresponds to the JSON property scaleUpMinWorkerFraction

Returns:
