I agree with this.

Having worked at FAANG, I'm always excited by the fanciness that is required. Spanner is the best database I've ever used.

That said, my feeling is that in the real world, you just pick Postgres and forget about it. Let's Encrypt issues every TLS cert on the Internet with one beefy Postgres database. Computers are HUGE these days. By the time a 128 core machine isn't good enough for your app, you will have sold your shares and will be living on your own private island or whatever. If you want to wrap sqlite in raft over the weekend for some fun, sure, do that. But don't put it in prod.

Agreed - A place I worked needed 24/7 uptime for financial transactions, and we still managed to keep scaling a standard MySQL database, despite it getting hammered, over the course of 10 years up to something like 64 cores and 384GB of RAM on a large EC2 instance.

We did have to move reporting off to a non-SQL solution because it was too slow to do in realtime, but that was a decision based on evidence of the need.
