RecordCache

RecordCache is a simple yet powerful extension to ActiveRecord that caches indexes and ActiveRecord models using MemCache. If you use it correctly, it will drastically reduce your database load.

Usage:

require 'record_cache'

class User < ActiveRecord
  record_cache :by => :id
  record_cache :id, :by => :username
end

# These will use the cache now.
User.find(1)
User.find_by_id(2)
User.find_all_by_username('chuck')

Invalidation is handled for you using callbacks. Be careful though if you modify records directly using SQL. Both update_all and delete_all handle invalidations for you, but other direct SQL will not.

Install:

sudo gem install record_cache -s http://gemcutter.org

Dependencies:

• after_commit
