alt Hacker NewsMaybe that too is a native question, but there's a large scale between single user and 6000 tweets per second - most of our apps will never reach anything approaching even one save a second. So where to draw the line? I do far have gone the sqlite route for my hobby apps as it's so easy to handle and doesn't require setting up two docker containers for a single app. Am I drawing myself in a corner in case my apps ever do become relevant?
Excellent question, and I spent so many years asking myself it, this over and over. You asking it made me realize I just...don't anymore. So allow me to blather a bit / free associate because I won't be sure why myself until I've written it out.
TL;DR: whatever works for you is the right decision. (which isn't helpful, I heard this so many times and as the recipient, I thought "That's nice. Now how do I choose what works for me?")
I finally had to use Postgres a couple years ago after a career of only SQLite - startup founder & iOS app developer using SQLite, turned Googler on Android, turned doing-my-own-thing.
In retrospect, I have made only one bad decision:
I went way out of my way to make SQLite work at my 2009-iOS-startup. It was a restaurant point of sale system, and to allow a networked system, one of the iOS devices would act as a server. This was a really cool trick, even an advantage in marketing that was appreciated by users. It meant the restaurant could continue to operate if the internet went down. But it eventually became clear owners loved having internet-based access too, ex. to do reporting/financial analysis over the data. And I kept contorting, instead of moving past my fear of getting into things I didn’t know, I instead did some like rudimentary thing over port forwarding. The bad decision here was riding one horse for so long and letting it affect the product, having a real server database would have allowed for a lot more features, think, first party gift cards, and a 100 others.
After leaving Google I needed server-side storage and fought and fought to avoid it. Then it turned out Postgres is easy and, just like SQLite, 99.999% of the time I don’t even know I’m using it.
In retrospect, there’s ~0 switching cost to these, particularly in age of LLMs. If you do need something more one day, it’ll be easy to do, and if you have to do it in a rush because you’re successful, you’re in Good Problem territory.
Hope that helped, after writing it out, dunno how convincing it is. Feel free to follow up, I appreciate the curiosity/framing because I had the same thought for so long.
