Class WeightedCluster

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, WeightedClusterOrBuilder, java.io.Serializable

    public final class WeightedCluster
    extends com.google.protobuf.GeneratedMessage
    implements WeightedClusterOrBuilder
     Compared to the :ref:`cluster <envoy_v3_api_field_config.route.v3.RouteAction.cluster>` field that specifies a
     single upstream cluster as the target of a request, the :ref:`weighted_clusters
     <envoy_v3_api_field_config.route.v3.RouteAction.weighted_clusters>` option allows for specification of
     multiple upstream clusters along with weights that indicate the percentage of
     traffic to be forwarded to each cluster. The router selects an upstream cluster based on the
     weights.

        envoy.config.route.v3.WeightedCluster.total_weight is deprecated. See envoy/config/route/v3/route_components.proto;l=477
         Specifies the total weight across all clusters. The sum of all cluster weights must equal this
         value, if this is greater than 0.
         This field is now deprecated, and the client will use the sum of all
         cluster weights. It is up to the management server to supply the correct weights.

      • getRuntimeKeyPrefix

        public java.lang.String getRuntimeKeyPrefix()
         Specifies the runtime key prefix that should be used to construct the
         runtime keys associated with each cluster. When the ``runtime_key_prefix`` is
         specified, the router will look for weights associated with each upstream
         cluster under the key ``runtime_key_prefix`` + ``.`` + ``cluster[i].name`` where
         ``cluster[i]`` denotes an entry in the clusters array field. If the runtime
         key for the cluster does not exist, the value specified in the
         configuration file will be used as the default weight. See the :ref:`runtime documentation
         <operations_runtime>` for how key names map to the underlying implementation.

        Returns:

      • hasHeaderName

        public boolean hasHeaderName()
         Specifies the header name that is used to look up the random value passed in the request header.
         This is used to ensure consistent cluster picking across multiple proxy levels for weighted traffic.
         If header is not present or invalid, Envoy will fall back to use the internally generated random value.
         This header is expected to be single-valued header as we only want to have one selected value throughout
         the process for the consistency. And the value is a unsigned number between 0 and UINT64_MAX.
         
        string header_name = 4 [(.validate.rules) = { ... }
        Specified by:
