Package io.envoyproxy.envoy.api.v2.route

Class WeightedCluster

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, WeightedClusterOrBuilder, Serializable
    public final class WeightedCluster
extends com.google.protobuf.GeneratedMessageV3
implements WeightedClusterOrBuilder
     Compared to the :ref:`cluster <envoy_api_field_route.RouteAction.cluster>` field that specifies a
 single upstream cluster as the target of a request, the :ref:`weighted_clusters
 <envoy_api_field_route.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.

      • getClustersCount

        public int getClustersCount()
         Specifies one or more upstream clusters associated with the route.
        repeated .envoy.api.v2.route.WeightedCluster.ClusterWeight clusters = 1 [(.validate.rules) = { ... }
        Specified by:
        getClustersCount in interface WeightedClusterOrBuilder

      • hasTotalWeight

        public boolean hasTotalWeight()
         Specifies the total weight across all clusters. The sum of all cluster weights must equal this
 value, which must be greater than 0. Defaults to 100.
        .google.protobuf.UInt32Value total_weight = 3 [(.validate.rules) = { ... }
        Specified by:
        hasTotalWeight in interface WeightedClusterOrBuilder
        Returns:
        Whether the totalWeight field is set.

      • getTotalWeight

        public com.google.protobuf.UInt32Value getTotalWeight()
         Specifies the total weight across all clusters. The sum of all cluster weights must equal this
 value, which must be greater than 0. Defaults to 100.
        .google.protobuf.UInt32Value total_weight = 3 [(.validate.rules) = { ... }
        Specified by:
        getTotalWeight in interface WeightedClusterOrBuilder
        Returns:
        The totalWeight.

      • getTotalWeightOrBuilder

        public com.google.protobuf.UInt32ValueOrBuilder getTotalWeightOrBuilder()
         Specifies the total weight across all clusters. The sum of all cluster weights must equal this

      • getRuntimeKeyPrefix

        public 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.
        string runtime_key_prefix = 2;
        Specified by:
        getRuntimeKeyPrefix in interface WeightedClusterOrBuilder
        Returns:
        The runtimeKeyPrefix.

      • getRuntimeKeyPrefixBytes

        public com.google.protobuf.ByteString getRuntimeKeyPrefixBytes()
         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.
        string runtime_key_prefix = 2;
        Specified by:
        getRuntimeKeyPrefixBytes in interface WeightedClusterOrBuilder
        Returns:
        The bytes for runtimeKeyPrefix.
