}Expand description
Describes an instance fleet, which is a group of EC2 instances that host a particular node type (master, core, or task) in an Amazon EMR cluster. Instance fleets can consist of a mix of instance types and On-Demand and Spot Instances, which are provisioned to meet a defined target capacity.
The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.id: Option<String>The unique identifier of the instance fleet.
name: Option<String>A friendly name for the instance fleet.
status: Option<InstanceFleetStatus>The current status of the instance fleet.
instance_fleet_type: Option<InstanceFleetType>The node type that the instance fleet hosts. Valid values are MASTER, CORE, or TASK.
target_on_demand_capacity: Option<i32>The target capacity of On-Demand units for the instance fleet, which determines how many
On-Demand Instances to provision. When the instance fleet launches, Amazon EMR tries to
provision On-Demand Instances as specified by InstanceTypeConfig. Each
instance configuration has a specified WeightedCapacity. When an On-Demand
Instance is provisioned, the WeightedCapacity units count toward the target
capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled,
even if this results in an overage. For example, if there are 2 units remaining to fulfill
capacity, and Amazon EMR can only provision an instance with a
WeightedCapacity of 5 units, the instance is provisioned, and the target
capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedOnDemandCapacity to determine the Spot capacity
units that have been provisioned for the instance fleet.
If not specified or set to 0, only Spot Instances are provisioned for the instance
fleet using TargetSpotCapacity. At least one of
TargetSpotCapacity and TargetOnDemandCapacity should be
greater than 0. For a master instance fleet, only one of TargetSpotCapacity
and TargetOnDemandCapacity can be specified, and its value must be
1.
target_spot_capacity: Option<i32>The target capacity of Spot units for the instance fleet, which determines how many Spot
Instances to provision. When the instance fleet launches, Amazon EMR tries to provision
Spot Instances as specified by InstanceTypeConfig. Each instance
configuration has a specified WeightedCapacity. When a Spot instance is
provisioned, the WeightedCapacity units count toward the target capacity.
Amazon EMR provisions instances until the target capacity is totally fulfilled, even if
this results in an overage. For example, if there are 2 units remaining to fulfill
capacity, and Amazon EMR can only provision an instance with a
WeightedCapacity of 5 units, the instance is provisioned, and the target
capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedSpotCapacity to determine the Spot capacity units
that have been provisioned for the instance fleet.
If not specified or set to 0, only On-Demand Instances are provisioned for the
instance fleet. At least one of TargetSpotCapacity and
TargetOnDemandCapacity should be greater than 0. For a master instance
fleet, only one of TargetSpotCapacity and
TargetOnDemandCapacity can be specified, and its value must be 1.
provisioned_on_demand_capacity: Option<i32>The number of On-Demand units that have been provisioned for the instance fleet to
fulfill TargetOnDemandCapacity. This provisioned capacity might be less than
or greater than TargetOnDemandCapacity.
provisioned_spot_capacity: Option<i32>The number of Spot units that have been provisioned for this instance fleet to fulfill
TargetSpotCapacity. This provisioned capacity might be less than or greater
than TargetSpotCapacity.
instance_type_specifications: Option<Vec<InstanceTypeSpecification>>An array of specifications for the instance types that comprise an instance fleet.
launch_specifications: Option<InstanceFleetProvisioningSpecifications>Describes the launch specification for an instance fleet.
Implementations
The current status of the instance fleet.
The node type that the instance fleet hosts. Valid values are MASTER, CORE, or TASK.
The target capacity of On-Demand units for the instance fleet, which determines how many
On-Demand Instances to provision. When the instance fleet launches, Amazon EMR tries to
provision On-Demand Instances as specified by InstanceTypeConfig. Each
instance configuration has a specified WeightedCapacity. When an On-Demand
Instance is provisioned, the WeightedCapacity units count toward the target
capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled,
even if this results in an overage. For example, if there are 2 units remaining to fulfill
capacity, and Amazon EMR can only provision an instance with a
WeightedCapacity of 5 units, the instance is provisioned, and the target
capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedOnDemandCapacity to determine the Spot capacity
units that have been provisioned for the instance fleet.
If not specified or set to 0, only Spot Instances are provisioned for the instance
fleet using TargetSpotCapacity. At least one of
TargetSpotCapacity and TargetOnDemandCapacity should be
greater than 0. For a master instance fleet, only one of TargetSpotCapacity
and TargetOnDemandCapacity can be specified, and its value must be
1.
The target capacity of Spot units for the instance fleet, which determines how many Spot
Instances to provision. When the instance fleet launches, Amazon EMR tries to provision
Spot Instances as specified by InstanceTypeConfig. Each instance
configuration has a specified WeightedCapacity. When a Spot instance is
provisioned, the WeightedCapacity units count toward the target capacity.
Amazon EMR provisions instances until the target capacity is totally fulfilled, even if
this results in an overage. For example, if there are 2 units remaining to fulfill
capacity, and Amazon EMR can only provision an instance with a
WeightedCapacity of 5 units, the instance is provisioned, and the target
capacity is exceeded by 3 units. You can use InstanceFleet$ProvisionedSpotCapacity to determine the Spot capacity units
that have been provisioned for the instance fleet.
If not specified or set to 0, only On-Demand Instances are provisioned for the
instance fleet. At least one of TargetSpotCapacity and
TargetOnDemandCapacity should be greater than 0. For a master instance
fleet, only one of TargetSpotCapacity and
TargetOnDemandCapacity can be specified, and its value must be 1.
The number of On-Demand units that have been provisioned for the instance fleet to
fulfill TargetOnDemandCapacity. This provisioned capacity might be less than
or greater than TargetOnDemandCapacity.
The number of Spot units that have been provisioned for this instance fleet to fulfill
TargetSpotCapacity. This provisioned capacity might be less than or greater
than TargetSpotCapacity.
An array of specifications for the instance types that comprise an instance fleet.
Describes the launch specification for an instance fleet.
