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.
