Latency strategy

This strategy selects a node which has the lowest latency, measured by periodic PING. Notice that the strategy only ping one of nodes from a single host. Due to the node list can be very long, it gets samples and selects the host with the lowest latency from only samples instead of the whole node list.

Usage

let broker = new ServiceBroker({
    registry: {
        strategy: "Latency"
    }
});

Strategy options

Usage with custom options

let broker = new ServiceBroker({
    registry: {
        strategy: "Latency",
        strategyOptions: {
            sampleCount: 15,
            lowLatency: 20,
            collectCount: 10,
            pingInterval: 15
        }
    }
});
