g index

:speedboat: Instant concurrent index migrations for Rails

Installation

Add this line to your application’s Gemfile:

gem "gindex", group: :development

How It Works

rails g index users email

generates:

class AddIndexOnEmailToUsers < ActiveRecord::Migration[7.0]
  disable_ddl_transaction!

  def change
    add_index :users, :email, algorithm: :concurrently
  end
end

Also works with multi-column indexes

rails g index deliveries store_id delivered_at

TODO

• add :name option to long index names
