N+1 query problem

• ORMs make it easy to a query per loop iteration, which we want to avoid

eager_load

• single query (left outer join)
• can reference the other table's columns in where

preload

• a few queries (one per table)
• typically faster

#  Monkey patch to ActiveRecord to prevent 'implicit' checkouts. Currently tested with Rails 4.0.8, prob
#  should work fine in Rails 4.1 too. 
#
#  If you create a thread yourself, if it uses ActiveRecord objects without
#  explicitly checking out a connection, one will still be checked out implicitly.
#  If it is never checked back in with `ActiveRecord::Base.clear_active_connections!`,
#  then it will be leaked.
