A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

What is this?

A way to encrypt data on mysql and then decrypt in javascript.

Why is this useful?

Sometimes you have data in your mysql database and you want to pass this data to a JS app.
For example, say you want to run an email campaign and you want to send emails to users from your mysql database. In this campaign you want ppl to click a link and when clicked you want the target site (your site) to be able to identify the user. You could pass the user-id as plaintext. Or the email as plain text. But that would be insulting the user's intelligence plus you might leak information "in the face" of a user. If you want to pass information from mysql to javascript and be able to obfuscate this info such that it isn't in the face of a user, this method is simple and effective.

This is not "secure"

In mongodb it's easy to make at upsert, meaning update-or-insert by calling

db.collection.update({criteria}, {updated fields}, true)

The third parameter means - insert a new document if the document doesn't exist yet. So, for example, the following will insert a new document for the user if there's no document for that user yet, and will update it if it already exists:

 db.users.update({user_id: '1234'}, {user_id: '1234', name: 'Ran'}, true)
