    • Method Detail

      • hasSlowStartWindow

        boolean hasSlowStartWindow()
         Represents the size of slow start window.
 If set, the newly created host remains in slow start mode starting from its creation time
 for the duration of slow start window.
        .google.protobuf.Duration slow_start_window = 1;

      • getSlowStartWindow

        com.google.protobuf.Duration getSlowStartWindow()
         Represents the size of slow start window.
 If set, the newly created host remains in slow start mode starting from its creation time
 for the duration of slow start window.
        .google.protobuf.Duration slow_start_window = 1;

      • getSlowStartWindowOrBuilder

        com.google.protobuf.DurationOrBuilder getSlowStartWindowOrBuilder()
         Represents the size of slow start window.
 If set, the newly created host remains in slow start mode starting from its creation time
 for the duration of slow start window.
        .google.protobuf.Duration slow_start_window = 1;

      • hasAggression

        boolean hasAggression()
         This parameter controls the speed of traffic increase over the slow start window. Defaults to 1.0,
 so that endpoint would get linearly increasing amount of traffic.
 When increasing the value for this parameter, the speed of traffic ramp-up increases non-linearly.
 The value of aggression parameter should be greater than 0.0.
 By tuning the parameter, is possible to achieve polynomial or exponential shape of ramp-up curve.
 During slow start window, effective weight of an endpoint would be scaled with time factor and aggression:
 `new_weight = weight * max(min_weight_percent, time_factor ^ (1 / aggression))`,
 where `time_factor=(time_since_start_seconds / slow_start_time_seconds)`.
 As time progresses, more and more traffic would be sent to endpoint, which is in slow start window.
 Once host exits slow start, time_factor and aggression no longer affect its weight.
        .envoy.config.core.v3.RuntimeDouble aggression = 2;
