In my opinion, there is but one feature that a database really must have: whatever data I write into it, if I don't delete it, I want to read it back - unaltered (preferably without needing at least three machines, but I'm willing to compromise)
Software that cannot provide this single feature just isn't something I would call database.
If it's unsafe default configurations or just bugs. I don't care.
Between these two articles over the weekend and some from earlier, personally, I don't trust MongoDB to still have that feature and as such, it needs much more than one article with a strongly worded title to convince me otherwise.

- adabsurdo 15y ago> preferably without needing at least three machines if you don't have such redundancy your data is not safe, no matter what database engine you are running.
- rdtsc 15y agoI see where you are headed but that is bad logic. It is like saying your car may catch on fire anytime or a meteorite can strike so why bother also wearing a seat belt? Sorry you cannot possibly defend un-acknowledged writes as a default setting on a product that calls itself a database. Saying you need 3 machines anyway. By coming up with more arguments and excuses as a defense for this design you are actually making the product you are defending look worse.
- adabsurdo 15y agoi didn't mean to imply that. i do agree that your db client should check for write errors if you care about your data, and that mongodb should make their official drivers have safer defaults. but the poster to which i was replying seemed to be saying that machine redundancy was somehow optional. it is not. hardware fails, and the architecture of whatever db server you are using is irrelevant when it does.
