This sounds awesome, but one of my first reactions to the notion of separated compute/storage Postgres with copy-on-write is "okay, so… slow Postgres?" Is there anything the dev team can share on read/write performance compared to RDS, NVMe EC2 instances, EBS-backed EC2, etc? In what situations would this setup perform poorly, and in what situations would it excel?
