How big can be one database size?

[merkdev]

Maybe this is related to #772 but I want to ask one more time with updated infra.

I want to know how big can be the turso database. I don't want to have a single db-per-user approach. Is there an upper cap to the size? Are there any gotchas if I use a single db like degraded performance after a certain size? I'm planning to use host my data-warehouse db and it's 12TB and growing.

Thanks!
