Struct PlacementGroupConfig

Source 
#[non_exhaustive]
pub struct PlacementGroupConfig {
    pub instance_role: Option<InstanceRoleType>,
    pub placement_strategy: Option<PlacementGroupStrategy>,
}
Expand description

Placement group configuration for an Amazon EMR cluster. The configuration specifies the placement strategy that can be applied to instance roles during cluster creation.

To use this configuration, consider attaching managed policy AmazonElasticMapReducePlacementGroupPolicy to the Amazon EMR role.

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.
§instance_role: Option<InstanceRoleType>

Role of the instance in the cluster.

Starting with Amazon EMR release 5.23.0, the only supported instance role is MASTER.

§placement_strategy: Option<PlacementGroupStrategy>

Amazon EC2 Placement Group strategy associated with instance role.

Starting with Amazon EMR release 5.23.0, the only supported placement strategy is SPREAD for the MASTER instance role.
