how to add muti job servers?

[askie]

I want to add 2 job servers as failover, how to do add 2 job servers? and how to register worker to muti job servers?

php have the method like this:

$gmclient= new GearmanClient();
$gmclient->addServers("10.0.0.1,10.0.0.2:7003");



$worker= new GearmanWorker(); 
$worker->addServers("10.0.0.1,10.0.0.2:7003");

Any news on this?

I've ceased using Gearman in favor of RabbitMQ and thus are not actively developing this module anymore, only making bug fixes etc.

Oh, I see.
Care to share your experiences on Gearman vs RabbitMQ?

[andris9]

Gearman is a fine product, it just turned out that most of the jobs that needed to be done were better handled asynchrounously in queues like provided by Rabbit. And as Rabbit can handle RPC-like calls also (although not as easy as with Gearman), there wasn't a reason to keep another dependency around.

Thanks for your input. I will check out rabbitmq!

I reckon that one could produce something like below to do even-distributed calls to a set of Gearman workers. I guess that keeping track of retries would be necessary before putting it into production:

Gearman = require("node-gearman")
workers = ["localhost", "localhost"]

sendJob = ->

  arglist = arguments

  worker = Math.floor(Math.random()*workers.length)
  gearman = new Gearman(workers[worker])
  job = gearman.submitJob.apply(gearman, arguments);

  job.setTimeout 3000

  gearman.on "connect", ->
    console.log "Connected to worker #" + worker + " @" + workers[worker]

  job.on "timeout", ->
    console.log "Timeout!"
    console.log "Retrying..."
    sendJob.apply(null, arglist); 
    gearman.close()

  job.on "error", (err) ->
    console.log "ERROR: ", err.message or err
    gearman.close()

  job.on "data", (reversed) ->
    console.log reversed.toString()

  job.on "end", ->
    console.log "Work finished"
    gearman.close()


sendJob("reverse", "test string")
