We live in wildly different worlds, I think. How is postgres comparable to 6-12 nodes of cassandra? One really giant one with 200k worth of storage? Is there even a multi-master setup yet? every time i’ve looked it’s just around the corner. multigres from supabase seems promising, but im not touching it for at least a couple years…
I’d love to use postgres, and have in various times in the past and love it (it never broke) — but one machine isn’t nearly big enough for really any of my current applications.
You can use a distributed database like yugabytedb or crdb. They are horizontally scalable, support postgres (yugabytedb has much better postgres compatibility). Yugabytedb also supports the Cassandra API.
I have high hopes for Neki from Planetscale but then again if you are not stuck on Postgres for whatever reason, Vitess with MySQL is about as battle tested as it gets.
