I'm really curious how people use these types of platforms in practice. It seems really easy to screw yourself over when you're "expirementing". The advice seems really obvious, but I'm sure I'd absent mindedly do a super naive query at some point and potentially cost my employer a lot of money.

I worked on a system to capture the production test data in a semiconductor company. We had trillions of rows and terabytes of data. While we were figuring stuff out, I'm sure I ran queries that scanned the entire dataset accidentally. I imagine one of those queries would have cost at least 1k to run. Our entire setup cost less than 10k a month to run on AWS regardless of how many queries we ran. I can't imagine spending 40k on 14gb of data regardless of what you were doing.

Yeah I mean I look at this example and it’s obviously pretty “extreme” - nobody is running that query every second (at least I hope not) - but I think the principle is important. You run that query once a day and it’s still costing you 1Kx what it would if it were optimized.
