It’s all relative. It’s cheap if you think about spinning up new processes to run one off commands. It gets very expensive when you have to spawn it hundreds of times per second, and it can waste cpu cycles that could be used for query processing instead.

This resonated with me a lot, thank you. It more or less matches what I have experienced, and it’s good to see someone write this down in a fairly balanced point of view.

My favourite parts:

> My job is to figure out the set of software approaches that match that estimate. […]

> Many engineers find this approach distasteful. […]

> If you refuse to estimate, you’re forcing someone less technical to estimate for you.

Even after many years, I still find it distasteful sometimes but I have to remind myself what everyone gets paid for at the end of the day.

Wouldn't need to worry about auto scaling Mongo yourself if you at that stage of the company though? You'd need to have quite a bit of traffic to need it. And if you do, hopefully you have generated $ needed to support it.
