fast_schema_dumper

A super fast alternative to ActiveRecord::SchemaDumper. Currently only MySQL is supported.

Requiring fast_schema_dumper/ridgepole will overwrite Ridgepole::Dumper.dump, which will force Ridgepole to use fast_schema_dumper.

RUBYOPT='-rridgepole -rfast_schema_dumper' ridgepole ... --apply

The Ridgepole integration is configurable via envionment variables.

• FAST_SCHEMA_DUMPER_MODE:
  • disabled: Use the original ActiveRecord dumper
  • verify: Run both dumpers and verify output matches (useful for testing)
  • Any other value or unset: Use FastSchemaDumper (default)
• FAST_SCHEMA_DUMPER_SUPPRESS_MESSAGE=1: Suppress the warning message when FastSchemaDumper is enabled

I recommend using only fast_schema_dumper in local development environments, and configuring FAST_SCHEMA_DUMPER_MODE=verify in CI setups.

Install the gem and add to the application's Gemfile by executing:

bundle add fast_schema_dumper

If bundler is not being used to manage dependencies, install the gem by executing:

gem install fast_schema_dumper

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
