Selects LB policy and provides corresponding configuration.

In general, all instances of this field should be repeated. Clients will iterate through the list in order and stop at the first policy that they support. This allows the service config to specify custom policies that may not be known to all clients.

  • If the config for the first supported policy is invalid, the whole service config is invalid.
  • If the list doesn't contain any supported policy, the whole service config is invalid.

The names of the methods to which this configuration applies.

  • MethodConfig without names (empty list) will be skipped.
  • Each name entry must be unique across the entire ServiceConfig.
  • If the 'method' field is empty, this MethodConfig specifies the defaults for all methods for the specified service.
  • If the 'service' field is empty, the 'method' field must be empty, and this MethodConfig specifies the default for all methods (it's the default config).

When determining which MethodConfig to use for a given RPC, the most specific match wins. For example, let's say that the service config contains the following MethodConfig entries:

method_config { name { } ... } method_config { name { service: "MyService" } ... } method_config { name { service: "MyService" method: "Foo" } ... }

MyService/Foo will use the third entry, because it exactly matches the service and method name. MyService/Bar will use the second entry, because it provides the default for all methods of MyService. AnotherService/Baz will use the first entry, because it doesn't match the other two.

In JSON representation, value "", value `null`, and not present are the same. The following are the same Name: - { "service": "s" } - { "service": "s", "method": null } - { "service": "s", "method": "" }

type ServiceConfig_LoadBalancingPolicy 

type ServiceConfig_LoadBalancingPolicy int32

Load balancing policy.

Note that load_balancing_policy is deprecated in favor of load_balancing_config; the former will be used only if the latter is unset.

If no LB policy is configured here, then the default is pick_first. If the policy name is set via the client API, that value overrides the value specified here.

If the deprecated load_balancing_policy field is used, note that if the resolver returns at least one balancer address (as opposed to backend addresses), gRPC will use grpclb (see https://github.com/grpc/grpc/blob/master/doc/load-balancing.md), regardless of what policy is configured here. However, if the resolver returns at least one backend address in addition to the balancer address(es), the client may fall back to the requested policy if it is unable to reach any of the grpclb load balancers.

type ServiceConfig_RetryThrottlingPolicy 

type ServiceConfig_RetryThrottlingPolicy struct {
	// The number of tokens starts at max_tokens. The token_count will always be
	// between 0 and max_tokens.
	//
	// This field is required and must be greater than zero.
	MaxTokens uint32 `protobuf:"varint,1,opt,name=max_tokens,json=maxTokens,proto3" json:"max_tokens,omitempty"`
	// The amount of tokens to add on each successful RPC. Typically this will
	// be some number between 0 and 1, e.g., 0.1.
	//
	// This field is required and must be greater than zero. Up to 3 decimal
	// places are supported.
	TokenRatio           float32  `protobuf:"fixed32,2,opt,name=token_ratio,json=tokenRatio,proto3" json:"token_ratio,omitempty"`

	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

If a RetryThrottlingPolicy is provided, gRPC will automatically throttle retry attempts and hedged RPCs when the client's ratio of failures to successes exceeds a threshold.

For each server name, the gRPC client will maintain a token_count which is initially set to max_tokens. Every outgoing RPC (regardless of service or method invoked) will change token_count as follows:

  • Every failed RPC will decrement the token_count by 1.
  • Every successful RPC will increment the token_count by token_ratio.

If token_count is less than or equal to max_tokens / 2, then RPCs will not be retried and hedged RPCs will not be sent.
