A relational database, like mysql, provides transactions to wrap several operations in one unit, make them all pass or all fail. All isolation levels except READ UNCOMMITTED don't allow read data changes until they are committed in other transaction. If you don't realize it, you probably introduce some unexpected errors. Optimize db migration. Nowadays it's easy to reach millions users for a startup website due to sns success, that means the tables on production server are huge, if you want to alter table structure, like add a new column, it may takes tens of minutes or several hours to execute.
If you want to add a new column and drop an existing column to one existing table, by default rails migration will run two alter sql statements, one for add and the other for drop, so it takes double time, but if we merge/optimize the two alter sql statements into one, it saves the migration time dramatically. The followings two are the typical cases to optimize the db migrations. Case 1: add a new column but drop it later db/migrate/20110930100808_add_status_to_users class AddStatusToUsers < ActiveRecord::Migration def self.up add_column :users, :status, :string endend. #382 Tagging. #366 Sidekiq.

Instead of giving you a thin layer over the HTTP server and saying "have at it!
