Struct AdaptiveLoadBalancer

Source

pub struct AdaptiveLoadBalancer { /* private fields */ }

Expand description

Router that picks the node with the lowest cpu_load from a ClusterMetrics snapshot. Falls back to deterministic-by-address order when there are no metrics.

Implementations§

Source §

impl AdaptiveLoadBalancer

Source

pub fn new(metrics: Arc<ClusterMetrics>) -> Self

Source

pub fn pick<'a>(&self, candidates: &'a [&'a str]) -> Option<&'a str>

Pick a candidate from candidates weighted by inverse load. Ties broken by address.
