This extension to the MysqlAdapter in ActiveRecord enables bulk updates to schema definitions. Pr. default when calling connection#add_column the change will be executed a once, but Mysql allows for multiple changes to be executed in one SQL statement (http://dev.mysql.com/doc/refman/5.1/en/alter-table.html). The advantage of this is that it takes a lot less time, especially if the table is large.

Most web applications have a lot of before/after hooks that occur when working with objects: sending a welcome email on registration, incrementing/decrementing counter caches, trigger validation on remote web services. When implemented using callbacks, all these occur without the developer knowing about them. A simple change in one area of the code can have a huge impact somewhere else. Inspiration for this came from http://blog.teksol.info/2010/09/28/unintented-consequences-the-pitfalls-of-activerecord-callbacks.html and http://jamesgolick.com/2010/3/14/crazy-heretical-and-awesome-the-way-i-write-rails-apps.html

Paranoia does this by setting a deleted_at field to the current time when you destroy a record, and hides it by scoping all queries on your model to only include records which do not have a deleted_at field.
