We have multiple CockroachDB clusters, have been for 4+ years now. From 2TB to 14TB in used size, the largest does about 3k/req sec.

We run them on dedicated hosts or on Hetzner cloud instances. We tested out RDS Postgres, but that would've literally tripled our cost for worse performance.

Only had a few hiccups with the big cluster but they were resolved quickly with their support.

We're very happy with the product, and have leaned quite a few optimization tricks to get the best out of it. Easy to use as well, join the nodes and it just works.

It's not perfect though, we've had quite a few issues with deleting lots of data at once, it doesn't like that. So we have to do deleted in smaller chunks.
