BackendServiceLocalityLoadBalancingPolicyConfigPolicy

public static enum BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name
extends Enum<BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name>
implements com.google.protobuf.ProtocolMessageEnum

 The name of a locality load-balancing policy. Valid values include ROUND_ROBIN and, for Java clients, LEAST_REQUEST. For information about these values, see the description of localityLbPolicy. Do not specify the same policy more than once for a backend. If you do, the configuration is rejected.

Enum Constant Detail

UNDEFINED_NAME

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name UNDEFINED_NAME

 A value indicating that the enum field is not set.
 

UNDEFINED_NAME = 0;

INVALID_LB_POLICY

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name INVALID_LB_POLICY

INVALID_LB_POLICY = 323318707;

LEAST_REQUEST

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name LEAST_REQUEST

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

LEAST_REQUEST = 46604921;

MAGLEV

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name 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
 

MAGLEV = 119180266;

ORIGINAL_DESTINATION

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name 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.
 

ORIGINAL_DESTINATION = 166297216;

RANDOM

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name RANDOM

 The load balancer selects a random healthy host.
 

RANDOM = 262527171;

RING_HASH

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name 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.
 

RING_HASH = 432795069;

ROUND_ROBIN

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name ROUND_ROBIN

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

ROUND_ROBIN = 153895801;

WEIGHTED_MAGLEV

public static final BackendServiceLocalityLoadBalancingPolicyConfigPolicy.Name WEIGHTED_MAGLEV

 Per-instance weighted Load Balancing via health check reported weights. If set, the Backend Service must configure a non legacy HTTP-based Health Check, and health check replies are expected to contain non-standard HTTP response header field X-Load-Balancing-Endpoint-Weight to specify the per-instance weights. If set, Load Balancing is weighted based on the per-instance weights reported in the last processed health check replies, as long as every instance either reported a valid weight or had UNAVAILABLE_WEIGHT. Otherwise, Load Balancing remains equal-weight. This option is only supported in Network Load Balancing.
 

WEIGHTED_MAGLEV = 254930962;

UNRECOGNIZED
