Launch HN: Ardent (YC P26) – Postgres sandboxes in seconds with zero migration

A little slow but on Aurora you can attach then promote read replicas. Iirc that's around 20 minutes but I haven't tested recently.

I'd think you could also setup logical rep to a VM then snapshot and clone the storage which is generally pretty fast.

You can create a new instance directly on AWS aurora. Takes less than 20 minutes!

  aws rds restore-db-cluster-to-point-in-time \
      --source-db-cluster-identifier <source-cluster> \
      --db-cluster-identifier <new-cluster> \                                         
      --restore-type copy-on-write \                                                   
      --use-latest-restorable-time \                                                   
      --db-subnet-group-name <sub group> \                     
      --vpc-security-group-ids <security group> \            
      --serverless-v2-scaling-configuration MinCapacity=0,MaxCapacity=16

Any idea on timing? I was under the impression pretty much anything RDS takes ~20 minutes although I haven't done any benchmarking/timing on the latest Aurora stuff

Main exceptions are copying/encrypting snapshots when they're not incremental and PITR restores which can take substantially longer.
