"So I won't have concurrency problems, right? ... Right?"
sqlite solves all your problems. you will certainly not regret running 50m sqlites
it's funny that this is like, Veteran Wisdom, but as a general rule postgres is fine, and if you are using something that is not postgres you had better have a good reason why it's not postgres.
sqlite is fine as long as you know it's small

No scale? No problem.
But off the top of my head I've run into: terrible concurrency w/per process connections, garbage and VACUUM overhead/performance, crappy heuristics query planner, WAL replication but DIY failover, no horizontal write scaling, write contention, jittery query latency, etc.

there is no reason to make a new database. postgres can do it. if you think postgres can't do it, you just haven't found the right way to enable it in pg_settings yet

I could actually see where that would actually be useful, e.g. you need concurrency and have no way to host it. Not ideal, but cool.

Preventing Overselling: Inventory Decrements Under Microsecond Concurrency
When systems face concurrency spikes, negative inventory counts when multiple carts check out simultaneously.
Core takeaway: Conditional atomic UPDATE with WHERE quantity >= :qty rather than SELECT-then-UPDATE.

I run qfn on a 4 x 5060ti threadripper. With concurrency 4. I get about 120 tok/s combined. 2000 prefill. Very usable. Usinh a fork of freetoken. Cancelled my OpenAI last week.

I ran MongoDB in 2011-2012 getting a startup off the ground. We got some pretty hecking great *concurrency* out of Mongo by treating it as it was actually built, not like it was a cheaper MySQL. This was before most of the table locking work was done!
I'd do it again.

there are ops people who will still never run mongo by choice, despite mean having basically won web mindshare for a number of years, because of how much trust they set on fire a decade ago, it's genuinely mind blowing
MongoDB became popular by doing essentially the 2010's equivalent of this. Rigor is as much as anything else about accurately conveying what you think you know and why. The problem isn't that AI wrote it, it's that you misrepresented it as more trustworthy than it is.

The Fallacy of 'Throw Redis at It' for Database Lock Contention
When systems face concurrency spikes, race conditions and cache stampedes under high concurrency.
Core takeaway: Redis object caching mitigates read pressure, but transactional writes still require serializable fences.

I agree. I think there is a sliver of positivity here, in that we should reinvent and maliciously enforce the epistemic standard for mission critical software (like the things that ground our distributed concurrency) to a level that it always should have had. See my prior post. :)
It's also the case that we should be demanding from our database vendors that they publish artifacts like Jepsen reports or the output of a system like Specula. We should inform our vendor decisions based on their demonstration of quality work. Which is GREAT, Actually!
