step1: build useful tool for serious people

step2: mention mongo

step3: enjoy having the room to yourself

I'm not here to really defend MongoDB, but the amazing thing about MongoDB is that, despite all the vitriol against it, it continues to be used at companies and projects that are far greater than what many naysayers ever touch: Stripe and Wish.com immediately come to my mind.

Also, I am giving MongoDB the benefit of the doubt per Curt Monash's law of databases:

Rule 1. It takes at least 7 years to build a database

Rule 2. You are not an exception to Rule 1.

I worked at bitly for a couple of years, we used mongodb for one of our secondary datastores. We had the expertise to keep it working, but we really hated it.

It's this funny situation where some engineer starts off using it because it's very convenient to run, and maybe the data model is convenient. You scale it up a bit, debug it, tune it, stuff you'd have to do with any system. At the point when you're sure mongo really sucks, it's too late. The business and even technical management side always prioritizes some other project over replacing it, even though you spend a surprising amount of time each month maintaining the mongodb cluster (performance degredation that compaction doesn't completely fix, and other stuff...).

I get the sense that with 3.0.3 or so, mongodb is a real database now. But it's been years of pain and false advertising. I'd still always vote against it. (Even though at my current place some people started using it for a service... :(

Facebook and Google(?) still use mysql.

I would still use mariadb or postgresql before mysql.

just because the big boys use it, doesn't mean it's good.

I honestly don't know if that mitigates against a lot of the MongoDB hate you see around here (including my post above). If I was at a place like Stripe and that money to pay Aphyr to battle-test all my database systems and an ops staff the handle all the issues that he found, then I could maybe deploy MongoDB successfully. I'd also have the sort of really, really hard problems that require me to spend that kind of resources on the problem. MongoDB is a much, much worse choice for those of us who DON'T have those needs and resources, though.
