Enum BackendSelectionStrategy 

pub enum BackendSelectionStrategy {
    WeightedRoundRobin,
    LeastLoaded,
}

Backend selection strategy for load balancing

Variants

WeightedRoundRobin

Weighted round-robin - distributes requests proportionally to max_connections

LeastLoaded

Least-loaded - routes to backend with fewest pending requests
