Sometimes, streaming makes sense. When I was at a FAANG, we had a sampled streaming database with nice plots (kinda, ugly but functional).

This was incredibly useful as it allowed teams to figure out what had happened in prod without needing to wait for the next day's batch jobs.

OTOH, most companies don't need something this complicated, and I'd imagine you could do the same with MySQL/Postgres if you're not at FAANG scale.
