Sometimes schema migrations are just not enough.

Data migration framework written in plain Ruby. Although originally created for migrating data in MongoDb, currently it is pretty generic, since it does not depend on any web framework.

This is a small migration framework that offers the following functionality for free:

1. Logging
2. Progress Bar
3. Gracefully handling when user interrupts (Ctrl+C or kill <process_id>)

Assuming that the migration strategy is implemented with a class MigrationStrategy, then executing a migration is quite simple:

migration_strategy  = MigrationStrategy.new
migration_framework = Kitcat::Framework.new(migration_strategy)
migration_framework.execute

The above will run the migration and will create a log file inside the log directory (which is created if not present)

How to implement MigrationStrategy

  bundle exec rake
