Struct aws_sdk_emr::types::PlacementGroupConfig

#[non_exhaustive]
pub struct PlacementGroupConfig { /* private fields */ }

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.
