The database choice is the easy half — your migration is the hard one
The hard half is migrating your existing data without losing rows, designing a schema your future-self will not curse, and getting realtime / vector / multi-region right when those matter. The 30-min call is where you describe your stack, your scale, your data shape; I tell you whether CockroachDB or Supabase (or something else) is your fit.
