Rails Indexes
Rails indexes is a small package of 2 rake tasks that scan your application models and displays a list of columns that probably should be indexed.
note: there should be mode fields depending on your application design and custom queries.
Installation
as a rails plugin:
script/plugin install git://github.com/eladmeidar/rails_indexes.git
Usage
Display a simple report:
rake db:show_me_some_indexes
– deprecated
Display a migration for adding/removing all necessary indexes based on associations:
rake db:show_me_a_migration
Display a migration for adding/removing all necessary indexes based on AR::Base#find calls (including: find, find_by, find_all_by, find_by_x_and_y, find_all_by_x_and_y):
rake db:show_me_ar_find_indexes
Note that it would probably make more sense running those tasks on production, where you actually need those indexes to be added.
- Add an option to create a migration that adds all the needed indexes.
- Add an option to scan the application root tree for #find, #find_all_by and #find_by to get some more index-required columns.
Tests
Requires SQLite3 installed, then just:
rake
to run the tests
