alt Hacker NewsThis is just untrue - the naive implementation (make the API call, write a single row to the db) will work fine, as transactions are quite fast on modern hardware.
What do you consider "serious" work? We've served a SaaS product from SQLite (roughly 300-500 queries per second at peak) for several years without much pain. Plus, it's not like PG and MySQL are pain-free, either - they all have their quirks.
Edit: disregard. I read it as he'd done it and had contention problems.
I mean it's not if he's got lock contention from BUSY signals, now is it, as he implies. Much of his issues will stem from transactions blocking each other; maybe they are long-lived, maybe they are not. And those 3-500 queries --- are they writes or reads? Because reads is not a problem.
