dq

High available beanstalkd.

consumer example

consumer := dq.NewConsumer(dq.DqConf{
	Beanstalks: []dq.Beanstalk{
		{
			Endpoint: "localhost:11300",
			Tube:     "tube",
		},
		{
			Endpoint: "localhost:11300",
			Tube:     "tube",
		},
	},
	Redis: redis.RedisConf{
		Host: "localhost:6379",
		Type: redis.NodeType,
	},
})
consumer.Consume(func(body []byte) {
	fmt.Println(string(body))
})

producer example

producer := dq.NewProducer([]dq.Beanstalk{
	{
		Endpoint: "localhost:11300",
		Tube:     "tube",
	},
	{
		Endpoint: "localhost:11300",
		Tube:     "tube",
	},
})	

for i := 1000; i < 1005; i++ {
	_, err := producer.Delay([]byte(strconv.Itoa(i)), time.Second*5)
	if err != nil {
		fmt.Println(err)
	}
}

kq

Kafka Pub/Sub framework

consumer example

config.json

Name: kq
Brokers:
- 127.0.0.1:19092
- 127.0.0.1:19092
- 127.0.0.1:19092
Group: adhoc
Topic: kq
Offset: first
Consumers: 1

example code

var c kq.KqConf
conf.MustLoad("config.json", &c)

q := kq.MustNewQueue(c, kq.WithHandle(func(k, v string) error {
	fmt.Printf("=> %s\n", v)
	return nil
}))
defer q.Stop()
q.Start()

producer example

type message struct {
	Key     string `json:"key"`
	Value   string `json:"value"`
	Payload string `json:"message"`
}


pusher := kq.NewPusher([]string{
	"127.0.0.1:19092",
	"127.0.0.1:19092",
	"127.0.0.1:19092",
}, "kq")

ticker := time.NewTicker(time.Millisecond)
for round := 0; round < 3; round++ {
	select {
	case <-ticker.C:
		count := rand.Intn(100)
		m := message{
			Key:     strconv.FormatInt(time.Now().UnixNano(), 10),
			Value:   fmt.Sprintf("%d,%d", round, count),
			Payload: fmt.Sprintf("%d,%d", round, count),
		}
		body, err := json.Marshal(m)
		if err != nil {
			log.Fatal(err)
		}

		fmt.Println(string(body))
		if err := pusher.Push(string(body)); err != nil {
			log.Fatal(err)
		}
	}
}
