Struct AssignmentConstraints 

Source 
pub struct AssignmentConstraints {
    pub max_partitions_per_node: u32,
    pub min_failure_domains: u32,
    pub anti_affinity_groups: Vec<Vec<u32>>,
    pub node_weights: HashMap<u64, f64>,
}
Expand description

Constraints for partition assignment.

Fields§

§max_partitions_per_node: u32

Maximum partitions per node (0 = no limit).

§min_failure_domains: u32

Minimum number of failure domains to spread across.

§anti_affinity_groups: Vec<Vec<u32>>

Anti-affinity groups: partitions in the same group should be on different nodes when possible.

§node_weights: HashMap<u64, f64>

Per-node weight overrides (node ID → weight). Default weight is proportional to core count.
