Documentation

Overview

Package config is a generated protocol buffer package.

The `redisquota` adapter can be used to support Istio's quota management system. It depends on a Redis server to store quota values.

This adapter supports the [quota template](https://istio.io/docs/reference/config/policy-and-telemetry/templates/quota/).

It is generated from these files: 

mixer/adapter/redisquota/config/config.proto

It has these top-level messages:

Types

type Params 

type Params struct {
	// The set of known quotas. At least one quota configuration is required
	Quotas []Params_Quota `protobuf:"bytes,1,rep,name=quotas" json:"quotas"`
	// Redis connection string <hostname>:<port number>
	// ex) localhost:6379
	RedisServerUrl string `protobuf:"bytes,2,opt,name=redis_server_url,json=redisServerUrl,proto3" json:"redis_server_url,omitempty"`
	// Maximum number of idle connections to redis
	// Default is 10 connections per every CPU as reported by runtime.NumCPU.
	ConnectionPoolSize int64 `protobuf:"varint,3,opt,name=connection_pool_size,json=connectionPoolSize,proto3" json:"connection_pool_size,omitempty"`
}

redisquota adapter supports the rate limit quota using either fixed or rolling window algorithm. And it is using Redis as a shared data storage.

Example configuration:

```yaml redisServerUrl: localhost:6379 connectionPoolSize: 10 quotas:

  • name: requestCount.quota.istio-system maxAmount: 50 validDuration: 60s bucketDuration: 1s rateLimitAlgorithm: ROLLING_WINDOW overrides:
  • dimensions: destination: ratings source: reviews maxAmount: 12
  • dimensions: destination: reviews maxAmount: 5

```
