Wordnik: 12 Months with MongoDB

Interesting performance stats, and 12 billion documents is a fairly substantial amount of data.

This is the first time I’ve seen major use of GridFS too:

We now store our audio files in MongoDB’s GridFS. Previously we used a clustered file system so files could be read and written from multiple servers. This created a huge amount of complexity from the IT operations point of view, and it meant that system backups (database + audio data) could get out of sync. Now that they’re in Mongo, we can reach them anywhere in the data center with the same mongo driver, and backups are consistent across the system.

Document vs Object Databases

This post from 10gen is a concise comparison between these seemingly similar technologies:

In a document store, we really are thinking of “documents”, not objects. Objects have methods, predefined schema, inheritance hierarchies. These are not present in a document database; code is not part of the database.

Integrating MongoDB and Django

Great overview by Kevin Fricovsky of MongoDB related technologies for working with Django.

If you are thinking about tinkering with MongoDB using Python then Django-Mumblr is a great first project to play around with and it uses the MongoEngine wrapper to make interfacing neater.
