Expand description

Configuration defining a new instance group.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§name: Option<String>

Friendly name given to the instance group.

§market: Option<MarketType>

Market type of the Amazon EC2 instances used to create a cluster node.

§instance_role: Option<InstanceRoleType>

The role of the instance group in the cluster.

§bid_price: Option<String>

If specified, indicates that the instance group uses Spot Instances. This is the maximum price you are willing to pay for Spot Instances. Specify OnDemandPrice to set the amount equal to the On-Demand price, or specify an amount in USD.

§instance_type: Option<String>

The Amazon EC2 instance type for all instances in the instance group.

§instance_count: Option<i32>

Target number of instances for the instance group.

§configurations: Option<Vec<Configuration>>

Amazon EMR releases 4.x or later.

The list of configurations supplied for an Amazon EMR cluster instance group. You can specify a separate configuration for each instance group (master, core, and task).

§ebs_configuration: Option<EbsConfiguration>

EBS configurations that will be attached to each Amazon EC2 instance in the instance group.

§auto_scaling_policy: Option<AutoScalingPolicy>

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates Amazon EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

§custom_ami_id: Option<String>

The custom AMI ID to use for the provisioned instance group.
