Module: Google::Cloud::Compute::V1::BackendServiceLocalityLoadBalancingPolicyConfigPolicy::Name

Defined in:
proto_docs/google/cloud/compute/v1/compute.rb

Overview

The name of a locality load balancer policy to be used. The value should be one of the predefined ones as supported by localityLbPolicy, although at the moment only ROUND_ROBIN is supported. This field should only be populated when the customPolicy field is not used. Note that specifying the same policy more than once for a backend is not a valid configuration and will be rejected.

Constant Summary collapse

UNDEFINED_NAME =

A value indicating that the enum field is not set.

INVALID_LB_POLICY =
323318707
LEAST_REQUEST =

An O(1) algorithm which selects two random healthy hosts and picks the host which has fewer active requests.

46604921
MAGLEV =

This algorithm implements consistent hashing to backends. Maglev can be used as a drop in replacement for the ring hash load balancer. Maglev is not as stable as ring hash but has faster table lookup build times and host selection times. For more information about Maglev, see https://ai.google/research/pubs/pub44824

119180266
ORIGINAL_DESTINATION =

Backend host is selected based on the client connection metadata, i.e., connections are opened to the same address as the destination address of the incoming connection before the connection was redirected to the load balancer.

166297216
RANDOM =

The load balancer selects a random healthy host.

262527171
RING_HASH =

The ring/modulo hash load balancer implements consistent hashing to backends. The algorithm has the property that the addition/removal of a host from a set of N hosts only affects 1/N of the requests.

432795069
ROUND_ROBIN =

This is a simple policy in which each healthy backend is selected in round robin order. This is the default.
