    ConfigParams
    public class DefaultConfigParamsImpl
extends Object
implements ConfigParams
    Default implementation of the ConfigParams.

    • Field Detail

      • HEART_BEAT_INTERVAL

        public static final scala.concurrent.duration.FiniteDuration HEART_BEAT_INTERVAL
        The interval at which a heart beat message will be sent to the remote RaftActor.

        Since this is set to 100 milliseconds the Election timeout should be at least 200 milliseconds
