Wordnik’s Experience with MongoDB

By: Erik Howard

Wordnik is an unconventional dictionary who’s goal is to show you as much information as possible, as fast as they can find it, for every word in English.

Wordnik is a heavy user of 10Gen’s nosql database MongoDB. They just recently blogged about their 1 year anniversary of moving from MySql to MongoDB. Some of the statistics include:

  • MongoDB servers an average of 500k requests/per hour. With 4x that number during peak periods
  • More than 12 billion documents stored by MongoDB
  • Around 3 TB storage per node
  • Easily sustained insert speeds of 8k documents/second, often with bursts to 50k documents/second
  • Every retrieval type is faster than MySql
    • example fetch time reduced from 400ms to 60ms
    • dictionary entries from 20ms to 1ms
    • document metadata from 30ms to .1ms
    • spelling suggestions from 10ms to 1.2ms

Mongomatic, A New MongoDB Ruby Library

By: Erik Howard

Mongomatic Ruby MongoDB Library

Mongomatic, from Ben Myles, is a new Ruby library for accessing MongoDB documents.

The primary design goals of Mongomatic are simplicity and adherence to MongoDB conventions. Mongomatic is not an ActiveRecord clone and has been designed to fit nicely with the document-oriented nature of MongoDB.

The library requires ActiveSupport (2 or 3) and the Ruby MongoDB driver.  Ruby versions 1.8.x and 1.9.x are supported. Other versions of Ruby may be supported but have not been tested.

Mongomatic can be installed from GitHub or via RubyGems.

GitHub

git clone http://github.com/benmyles/mongomatic.git

Ruby Gems

gem install mongomatic
