Free Online MongoDB Training by 10gen

10gen really nailed this; the meetup groups, customer support, drivers, docs and ability to get going are all awesome compared to most products, let alone the other databases competing with them.

All databases do not like to give back space they have allocated because allocating space is an expensive operation. You probably don't need to compact the db, unless you have a problem with file size (which in some scenarios I have had this issue).

There's nothing built in that I know of, but you can easily just make something that runs on a regular basis like a scheduled task or cron job that runs either compact command or repair database command.

I can hook you up with some stickers. meghan @ 10gen.com

Despite not knowing anything about your dataset and insertion/deletion patterns, you may want to consider power of two allocation. It's a new feature in 2.2 that costs some additional disk space up front (new documents potentially get 2x padding), but can save a lot of disk over the long run by eliminating many data access patterns that add to fragmentation. One (pathological) benchmark I ran saved 800x the disk space after 1,000K (edited from 100K), insertions and deletes of 1-10KB documents.

Where is edX mentioned?

Also, any idea when edX will be available as open source?

I stopped registering when that link didn't work.

It seems like you'll be able to watch at your own pace, it says "10hrs/week estimate"

It's very similar to Udacity's courses which are about 12 hours each http://www.udacity.com/

This course will be different due to browser-based MongoDB shells for completing exercises like testing queries and spinning up replica sets. You can walk through a lot of the material on your on due to the 10gen presentations and MongoDB Docs, but it's even better when you're guided through the concepts in the shell.

Yeah, I was surprised at the length of time they recommend -- 10 hours/week for 7 weeks (for the developer course). 70 hours? I would think you could get productive in this in much less time.
