Method Summary

Modifier and Type	Method and Description
RuntimeDouble	getActiveRequestBias() The following formula is used to calculate the dynamic weights when hosts have different load balancing weights: `weight = load_balancing_weight / (active_requests + 1)^active_request_bias` The larger the active request bias is, the more aggressively active requests will lower the effective weight when all host weights are not equal.

Method Detail

hasChoiceCount

boolean hasChoiceCount()

 The number of random healthy hosts from which the host with the fewest active requests will
 be chosen. Defaults to 2 so that we perform two-choice selection if the field is not set.
 

.google.protobuf.UInt32Value choice_count = 1 [(.validate.rules) = { ... }

getChoiceCount

com.google.protobuf.UInt32Value getChoiceCount()

 The number of random healthy hosts from which the host with the fewest active requests will
 be chosen. Defaults to 2 so that we perform two-choice selection if the field is not set.
 

.google.protobuf.UInt32Value choice_count = 1 [(.validate.rules) = { ... }

getChoiceCountOrBuilder

com.google.protobuf.UInt32ValueOrBuilder getChoiceCountOrBuilder()

 The number of random healthy hosts from which the host with the fewest active requests will
 be chosen. Defaults to 2 so that we perform two-choice selection if the field is not set.
 

.google.protobuf.UInt32Value choice_count = 1 [(.validate.rules) = { ... }

hasActiveRequestBias

boolean hasActiveRequestBias()

 The following formula is used to calculate the dynamic weights when hosts have different load
 balancing weights:
 `weight = load_balancing_weight / (active_requests + 1)^active_request_bias`
 The larger the active request bias is, the more aggressively active requests will lower the
 effective weight when all host weights are not equal.
 `active_request_bias` must be greater than or equal to 0.0.
 When `active_request_bias == 0.0` the Least Request Load Balancer doesn't consider the number
 of active requests at the time it picks a host and behaves like the Round Robin Load
 Balancer.
 When `active_request_bias > 0.0` the Least Request Load Balancer scales the load balancing
 weight by the number of active requests at the time it does a pick.
 The value is cached for performance reasons and refreshed whenever one of the Load Balancer's
 host sets changes, e.g., whenever there is a host membership update or a host load balancing
 weight change.
 .. note::
   This setting only takes effect if all host weights are not equal.
