Types

type RateLimitRequest

type RateLimitRequest struct {
	// All rate limit requests must specify a domain. This enables the configuration to be per
	// application without fear of overlap. E.g., "envoy".
	Domain string `protobuf:"bytes,1,opt,name=domain,proto3" json:"domain,omitempty"`
	// All rate limit requests must specify at least one RateLimitDescriptor. Each descriptor is
	// processed by the service (see below). If any of the descriptors are over limit, the entire
	// request is considered to be over limit.
	Descriptors []*ratelimit.RateLimitDescriptor `protobuf:"bytes,2,rep,name=descriptors,proto3" json:"descriptors,omitempty"`
	// Rate limit requests can optionally specify the number of hits a request adds to the matched
	// limit. If the value is not set in the message, a request increases the matched limit by 1.
	HitsAddend           uint32   `protobuf:"varint,3,opt,name=hits_addend,json=hitsAddend,proto3" json:"hits_addend,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

Main message for a rate limit request. The rate limit service is designed to be fully generic in the sense that it can operate on arbitrary hierarchical key/value pairs. The loaded configuration will parse the request and find the most specific limit to apply. In addition, a RateLimitRequest can contain multiple "descriptors" to limit on. When multiple descriptors are provided, the server will limit on *ALL* of them and return an OVER_LIMIT response if any of them are over limit. This enables more complex application level rate limiting scenarios if desired.
