If we know the alias tracker is empty, we can create one that doesn't
use a hash with default block for counting.
ActiveRecord::Base.establish_connection(adapter: 'sqlite3',
database: ':memory:')
ActiveRecord::Schema.define do
create_table :posts, force: true do |t|
t.integer :comments_count
end
create_table :comments, force: true do |t|
t.integer :post_id
end
end
class Post < ActiveRecord::Base; has_many :comments; end
class Comment < ActiveRecord::Base; belongs_to :post, counter_cache: true; end
10.times { Comment.create!(post: Post.create!) }
record = Post.first
association_name = :comments
Benchmark.ips do |x|
reflection = record.class.reflect_on_association(association_name)
association = reflection.association_class.new(record, reflection)
x.report('assoc') do
reflection.association_class.new(record, reflection)
end
x.report('reader') do
association.reader;nil
end
x.report('combined') do
reflection.association_class.new(record, reflection).reader;nil

This helps with our sanity. The class is internal, we can refactor to a
"nice" API later.

Outer joins were being built on the root relation klass rather than the
one specified in the join dependency root

According to our guideline, we leave 1 space between `#` and `=>`, so we
want `# =>` instead of `#=>`.
Thanks to @fxn for the suggestion.

turns out that the activerecord object will always have the same id as
the row from which it was constructed

Remove duplicate removal code because we avoid adding duplicates as we
walk the tree the first time

We don't need to poke at the macro to figure out if we should look for a
cached record or not

For now, we'll set the tables on the nodes manually.
