Struct RebalanceTrigger

Source

pub struct RebalanceTrigger {
    pub min_imbalance_ratio: f32,
    pub max_p95_latency_ms: f32,
}

Expand description

Trigger mechanism for dynamic rebalancing based on load/health.

Implementations§

Source §

impl RebalanceTrigger

Source

pub fn evaluate( &self, cluster: &ClusterState, current_plan: &PlacementPlan, ) -> Option<MigrationPlanner>

Evaluates if cluster migration is needed due to load or latency imbalance.

OPTIMIZATION: Consolidates node counting and overtaxed/available node search into a single pass over node metrics under lock. Borrows string references (&str) during traversal, allocating owned Strings only when a migration candidate pair is confirmed.
