Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
This is very cool! I no longer work on Rails on daily basis, but would have loved to have this.
I built something similar called `pg-osc` / `pg-online-schema-change` for PostgreSQL workloads. It does zero downtime migrations using triggers and shadow table.

Also love that this is written in Ruby :). Going to check it out on some side projects.

Pgroll: zero-downtime, undoable, schema migrations for Postgres
Very cool! Congratulations to the authors on the release! I'm the author of a similar (zero-downtime migration) tool for PG called QuantumDB[0]. It was the first (to my knowledge at least) tool to support foreign keys, by creating table copies (keeping those in sync using triggers), and exposing multiple schemas through a custom database driver. I never got to production-ready version unfortunately, but I'm happy this one did. I'm seeing a lot of familiar concepts, and it looks well thought out.
