Standout Features of MongoDB
Why? Because, in the early stages of product development, I am rapidly iterating on the domain, and other parts of the app. Sometimes changing my mind on major pieces of the architecture as we prototype early solutions.
MongoDB works as freely and as quickly as I do. SQL databases do not. They get in the way, slow me down, tick me off.
However, not all apps are well-suited for NOSQL. So if there are performance needs or other reasons that may point to SQL, then at some point I migrate.
Controversial, I can imagine. But I could explain it over a beer. Or three.
