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.

Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
This is cool. We use strong_migrations but I’ll check this out. I love the idea of an enforced pattern for background data migrations.
While I’m here a shameless plug for a gem we built that we’ve found incredibly helpful for safer migrations - https://github.com/TandaHQ/migration_signature
It adds a CI check to guarantee the migrations you tested in development are actually the migrations that run in production.
