Types

type LoadReportingServiceClient 

type LoadReportingServiceClient interface {
	// Advanced API to allow for multi-dimensional load balancing by remote
	// server. For receiving LB assignments, the steps are:
	// 1, The management server is configured with per cluster/zone/load metric
	//    capacity configuration. The capacity configuration definition is
	//    outside of the scope of this document.
	// 2. Envoy issues a standard {Stream,Fetch}Endpoints request for the clusters
	//    to balance.
	//
	// Independently, Envoy will initiate a StreamLoadStats bidi stream with a
	// management server:
	// 1. Once a connection establishes, the management server publishes a
	//    LoadStatsResponse for all clusters it is interested in learning load
	//    stats about.
	// 2. For each cluster, Envoy load balances incoming traffic to upstream hosts
	//    based on per-zone weights and/or per-instance weights (if specified)
	//    based on intra-zone LbPolicy. This information comes from the above
	//    {Stream,Fetch}Endpoints.
	// 3. When upstream hosts reply, they optionally add header <define header
	//    name> with ASCII representation of EndpointLoadMetricStats.
	// 4. Envoy aggregates load reports over the period of time given to it in
	//    LoadStatsResponse.load_reporting_interval. This includes aggregation
	//    stats Envoy maintains by itself (total_requests, rpc_errors etc.) as
	//    well as load metrics from upstream hosts.
	// 5. When the timer of load_reporting_interval expires, Envoy sends new
	//    LoadStatsRequest filled with load reports for each cluster.
	// 6. The management server uses the load reports from all reported Envoys
	//    from around the world, computes global assignment and prepares traffic
	//    assignment destined for each zone Envoys are located in. Goto 2.

	//    that is observed in between the corresponding previous *LoadStatsRequest* and this
	//    *LoadStatsResponse* will also be accumulated and billed to the cluster. This avoids a period
