Circuit breakers

cluster.CircuitBreakers

Circuit breaking settings can be specified individually for each defined priority.

{
  "thresholds": []
}

thresholds

(cluster.CircuitBreakers.Thresholds) If multiple Thresholds are defined with the same RoutingPriority, the first one in the list is used. If no Thresholds is defined for a given RoutingPriority, the default values are used.

A Thresholds defines CircuitBreaker settings for a RoutingPriority.

{
  "priority": "...",
  "max_connections": "{...}",
  "max_pending_requests": "{...}",
  "max_requests": "{...}",
  "max_retries": "{...}"
}

priority

(core.RoutingPriority) The RoutingPriority the specified CircuitBreaker settings apply to.

max_connections

(UInt32Value) The maximum number of connections that Envoy will make to the upstream cluster. If not specified, the default is 1024.

max_pending_requests

(UInt32Value) The maximum number of pending requests that Envoy will allow to the upstream cluster. If not specified, the default is 1024.

max_requests

(UInt32Value) The maximum number of parallel requests that Envoy will make to the upstream cluster. If not specified, the default is 1024.

max_retries

(UInt32Value) The maximum number of parallel retries that Envoy will allow to the upstream cluster. If not specified, the default is 3.
