Excellent write-up, thanks. I see there is a lot of interest on this topic…

I have written a new administrative front-end for WordPress with Mass Publishing in mind. I had looked at the flexibility of Postgres because some of the interactive objects I’d like to include in the system architecture (in the social media realm) aren’t typical data.

Then when I explained what I had to one of my mentors, he said “it sounds like you really need to take the RDBMS out of the equation.” I immediately saw the usefulness in that based on the needs of my application- speed being one of them. Like everything, technology should be fit to the task. Wouldn’t take a cadillac limo offroad would you?

Thanks for this complete perspective on your mission and your journey to an effective solution for your company. It has been valuable as I have started making decisions about the database I will use before I develop a new framework and break out of WordPress altogether.

Yep. And like David said, mapping is a simple, trivial task. You can have your cake and eat it too.

This mapping can also be handled at the code level with very little overhead.

Oracle is not a serious choice for startups due to the cost.

We’ve got over 2TB of data in an Oracle Database, with user loading between 10GB and 50GB of data per day, while others are querying the database.

For scaling purposes, we’ve got RAC.

Works fine, and no need to separate loading and querying, as locks are row-based.

If your main concern was the need for fast loading, why didn’t you go the Oracle route, then?

This was based off two blog posts – why we migrated to MongoDB and notes from a production deployment.

The audio in this presentation is barely audible.

Please can you provide another alternative?

As you mentioned that you have more Read Operations than Write Operation.My question is that how are you populating the Mongo DB Collections.I think there must be sufficient write operations as well.
