I worked for startup who did all of these things on CockroachDB. We could of used a single m5.xlarge PostgreSQL instance (1000 basic QPS on 150GB of data) if we optimized our queries and went back to basics, instead we had 1TB of RAM dedicated to Cockroach.

I added about 4 indexes and halved the resources overnight. But Prisma, SELECT *, graphql and what other resume building shit people implemented was the bane of my existence, typically engineers did this believing it would be faster. I remember 1 engineer had a standing ovation in slack for his refactor which was supposedly going to save us $$$$$ except our DB CPU went up 30% because he decided to validate every company every second in every session. In his defense, he added 1 line of code that caused it, and it was obscured through prisma and graphql to an inefficient query.

FWIW; I love CockroachDB but the price is directly linked to how much your software engineers shit on the database.
