# drift NSQ Producer/Consumer integration to drift your request smoothly. Add/Kill consumer over http request on any topic. Publish new request over http on any nsqd.

STEPS TO RUN drift

1. install nsq
2. go get github.com/mayur-tolexo/drift
3. cd $GOPATH/src/github.com/mayur-tolexo/drift
4. install godep
5. godep restore
6. go run example/drift.go
7. [in new tab] cd $GOPATH/src/github.com/mayur-tolexo/drift
8. go run nsqlookup/nsqlookup.go
9. [in new tab] cd $GOPATH/src/github.com/mayur-tolexo/drift
10. go run nsqd/nsqd.go --lookupd-tcp-address=127.0.0.1:4160
11. [in new tab] cd $GOPATH/src/github.com/mayur-tolexo/drift
12. go run example/producer.go
13. add new consumer as mention below
14. start admin as mention below
15. open http://127.0.0.1:4171/ in browser

START ADMIN

POST localhost:1500/drift/v1/start/admin/

{
  "lookup_http_address": ["127.0.0.1:4161"],
  "http_address":"localhost:4171",
  "user": ["drift-user"],
  "acl_http_header": "admin-user"
}

STOP ADMIN

GET localhost:1500/drift/v1/stop/admin/

ADD NEW CONSUMER

POST localhost:1500/drift/v1/add/consumer/

{
  "lookup_http_address": [
    "127.0.0.1:4161"
  ],
  "topic_detail": [
    {
      "topic": "elastic",
      "channel": "v2.1",
      "count": 1
    },
    {
      "topic": "elastic",
      "channel": "v6.2",
      "count": 2
    }
  ],
  "max_in_flight": 200
}

COUNT CONSUMERS OF A TOPIC ON SPECIFIC CHANNEL

GET localhost:1500/drift/v1/consumer/?topic=elastic&channel=v2.1

COUNT ALL CONSUMERS OF A TOPIC

GET localhost:1500/drift/v1/consumer/?topic=elastic

KILL CONSUMER

POST localhost:1500/drift/v1/kill/consumer/

{
  "topic": "elastic",
  "channel": "v2.1",
  "count":1
}

PUBLISH REQUEST

POST localhost:1500/drift/v1/pub/request/

{
  "nsqd_tcp_address": ["127.0.0.1:4150"],
  "topic": "elastic",
  "data": "This is a test over http"
}

Example

//printIT : function which consumer will call to execute
func printIT(value ...interface{}) error {
  fmt.Println(value)
  return nil
}

func main() {
  d := drift.NewConsumer(printIT)
  d.Start(1500)
}

Handler

handler is a function to which the consumer will call.

FUNCTION DEFINATION:
func(value ...interface{}) error

Here PrintIT is a handler function. Define your own handler and pass it in the drift and you are ready to go.
