Within our sense, the danger is losing data is really, very, really small – and you can we’re not powering a bank. With the best transactional database isn’t really a dependence on us.

Worst circumstances circumstance? You to definitely associate texts various other therefore the content will not read. One to a perfectly appropriate chance, if it is in contrast to the advantages of having a premier-efficiency solution. We really such as for instance Mongo: the have fun with relies on your form of software and texture you prefer, but it’s a great choice for people.
