MongoDB rocks my world

Re:MongoDB rocks my world by djb_hackernews on Monday October 31, 2011 @03:45PM (#3178703)

I REALLY want to try mongo for a side project I am building, however the single server durability is an issue. My data could easily fit in mysql/postgres however I am storing data that fits better in a document store. I am inclined to just use postgres for now because it's sort of silly to set up/pay for multiple servers for such a small project.

UPDATE: Apparently my information is out of date. Hopefully my confusion (and the answers below) helps someone else. Thanks.

MongoDB has had single server durability since 1.8. It's now on 2.0 and enabled by default.

afaik single server durability was a problem in the past. Since 1.8 they've introduced journaling and it's now enabled by default in 2.0 More info here: http://blog.mongodb.org/post/381927266/what-about-durability and here: http://www.mongodb.org/display/DOCS/Durability+and+Repair

MongoDB has single server durability since 1.8 with the journal. If you put the journal on an SSD, you can even get it almost for free performance-wise.

Yeah, I guess I should make the point that if you don't put the journal on SSD (and you only need a few gigs of SSD to journal terabytes of spinning disk storage), you will see significant slowdown.

You could say that about any database, though - nothing special about mongo's journaling that makes it "for free" wit h an SSD.
