How does planetscale for postgres scale? I understand that it's multi node postgres with automatic failover but I think it only really scales for reads and not writes? So is the only way to scale writes horizontally to shard?
Kind of. For horizontally scaling writes we are building the Vitess for Postgres which we are calling Neki https://www.neki.dev/
The product we are GA'ing today has the option of PlanetScale Metal which is extremely fast and scales write QPS further than any of the other single-primary Postgres hosts.
Thanks for the response, this clarifies things for me because I thought this was already a vitess for postgress implementation. Awesome to hear that this is coming.
