    <p>I'm not a node.js master, so I'd like to have more points of view about this.</p> <p>I'm creating an HTTP node.js web server that must handle not only lots of concurrent connections but also long running jobs. By default node.js runs on one process, and if there's a piece of code that takes a long time to execute any subsequent connection must wait until the code ends what it's doing on the previous connection.</p> <p>For example:</p> <pre><code>var http = require('http'); http.createServer(function (req, res) { doSomething(); // This takes a long time to execute // Return a response }).listen(1337, "127.0.0.1"); </code></pre> <p>So I was thinking to run all the long running jobs in separate threads using the <a href="https://github.com/pgriess/node-webworker">node-webworker</a> library:</p> <pre><code>var http = require('http'); var sys = require('sys'); var Worker = require('webworker'); http.createServer(function (req, res) { var w = new Worker('doSomething.js'); // This takes a long time to execute // Return a response }).listen(1337, "127.0.0.1"); </code></pre> <p>And to make the whole thing more performant, I thought to also use <a href="http://learnboost.github.com/cluster/">cluster</a> to create a new node process for each CPU core.</p> <p>In this way I expect to balance the client connections through different processes with <code>cluster</code> (let's say 4 node processes if I run it on a quad-core), and then execute the long running job on separate threads with <code>node-webworker</code>.</p> <p>Is there something wrong with this configuration?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
