    • getSingleHostPerSubset

      public boolean getSingleHostPerSubset()
       Selects a mode of operation in which each subset has only one host. This mode uses the same rules for
 choosing a host, but updating hosts is faster, especially for large numbers of hosts.

 If a match is found to a host, that host will be used regardless of priority levels.

 When this mode is enabled, configurations that contain more than one host with the same metadata value for the single key in ``keys``
 will use only one of the hosts with the given key; no requests will be routed to the others. The cluster gauge
 :ref:`lb_subsets_single_host_per_subset_duplicate<config_cluster_manager_cluster_stats_subset_lb>` indicates how many duplicates are
 present in the current configuration.
      bool single_host_per_subset = 4;
      Specified by:
      getSingleHostPerSubset in interface Subset.LbSubsetSelectorOrBuilder
      Returns:
      The singleHostPerSubset.

    • getFallbackPolicyValue

 metadata.
      .envoy.extensions.load_balancing_policies.subset.v3.Subset.LbSubsetSelector.LbSubsetSelectorFallbackPolicy fallback_policy = 2 [(.validate.rules) = { ... }
      Specified by:
      getFallbackPolicyValue in interface Subset.LbSubsetSelectorOrBuilder
      Returns:
      The enum numeric value on the wire for fallbackPolicy.

    • getFallbackPolicy

      public Subset.LbSubsetSelector.LbSubsetSelectorFallbackPolicy getFallbackPolicy()
