Struct rusoto_emr::SpotProvisioningSpecification

pub struct SpotProvisioningSpecification {
    pub block_duration_minutes: Option<i64>,
    pub timeout_action: String,
    pub timeout_duration_minutes: i64,
}

The launch specification for Spot instances in the instance fleet, which determines the defined duration and provisioning timeout behavior.

The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.

Fields

block_duration_minutes: Option<i64>

The defined duration for Spot instances (also known as Spot blocks) in minutes. When specified, the Spot instance does not terminate before the defined duration expires, and defined duration pricing for Spot instances applies. Valid values are 60, 120, 180, 240, 300, or 360. The duration period starts as soon as a Spot instance receives its instance ID. At the end of the duration, Amazon EC2 marks the Spot instance for termination and provides a Spot instance termination notice, which gives the instance a two-minute warning before it terminates.

timeout_action: String

The action to take when TargetSpotCapacity has not been fulfilled when the TimeoutDurationMinutes has expired. Spot instances are not uprovisioned within the Spot provisioining timeout. Valid values are TERMINATE_CLUSTER and SWITCH_TO_ON_DEMAND. SWITCH_TO_ON_DEMAND specifies that if no Spot instances are available, On-Demand Instances should be provisioned to fulfill any remaining Spot capacity.

timeout_duration_minutes: i64

The spot provisioning timeout period in minutes. If Spot instances are not provisioned within this time period, the TimeOutAction is taken. Minimum value is 5 and maximum value is 1440. The timeout applies only during initial provisioning, when the cluster is first created.
