node-hashtable/index.js

This is a simple hashtable, all written in node, to help you access and store your data over multiple workers or modules. It will provide the abstraction to access it through workers (cluster).

var net = require("net");
var cluster = require("cluster");

var port = 0;
var host = "localhost";

var hashTable = require('./hashtable.js');

var client = require("./client.js");

var server = require("./server.js");


module.exports = client.exchange;


if (cluster.isMaster) {
        /* If he is master, dont need to access throught data throught socket */
        client.master(1);
        
        /* Connect workers client to server */
        cluster.on('online', function(worker) {
            (function wait_exchange_server() {
                if(server.port() !== 0) {
                    worker.send({
                        hashtable_msg: 1,
                        port: server.port(),
                        host: server.host()
                    });
                }
                else {
                    setTimeout(function() { wait_exchange_server() }, 100);
                }
            })();
        });
}
else if (cluster.isWorker) {
    process.on('message', function(data) {
        if(data && data.hashtable_msg) {
            client(data.port, data.host);
        }
    })
