Clustering / Multi-Core Server

[Glavin001]

Support for Cluster to create a multi-core Node.js server.

• Use Cluster with Express
• Use Redis Store for Socket.io.

This could be a plugin for Feathers, or a built-in feature as is Socket.io and Primus.

---

Example of using Cluster:

Source http://adamnengland.wordpress.com/2013/01/30/node-js-cluster-with-socket-io-and-express-3/

cluster = require("cluster")
http = require("http")
numCPUs = require("os").cpus().length
RedisStore = require("socket.io/lib/stores/redis")
redis = require("socket.io/node_modules/redis")
pub = redis.createClient()
sub = redis.createClient()
client = redis.createClient()
if cluster.isMaster
  i = 0
  while i < numCPUs     cluster.fork()     i++   cluster.on 'fork', (worker) ->
    console.log 'forked worker ' + worker.process.pid
  cluster.on "listening", (worker, address) ->
    console.log "worker " + worker.process.pid + " is now connected to " + address.address + ":" + address.port
  cluster.on "exit", (worker, code, signal) ->
    console.log "worker " + worker.process.pid + " died"
else
  app = require("express")()
  server = require("http").createServer(app)
  io = require("socket.io").listen(server)
  io.set "store", new RedisStore(
    redisPub: pub
    redisSub: sub
    redisClient: client
  )
  server.listen 8000
  app.get "/", (req, res) ->
    res.sendfile(__dirname + '/index.html');
  io.sockets.on "connection", (socket) ->
    console.log 'socket call handled by worker with pid ' + process.pid
    socket.emit "news",
      hello: "world"

Are you up for providing a PR? 😄

Sounds more like a plugin to me. We had to do some work on making stuff distributed recently too, so I think providing some help there would make sense. I'll read through the article but ideas are definitely welcome.

[Glavin001]

Absolutey. @ekryski. I will need a little help getting started, as I am new to Feathers and have no concept of how best to start a plugin.

@daffl, do we have a plugin repository or documentation on how to build a plugin properly for Feathers? I can get started tonight.

[daffl]

It'd be the first :) I'm planning put a sample plugin repository up though (to also work on #22) and I'll let you know.

Awesome, thanks!
