SerializeYAML2JSON

ActiveRecord::Coder to transparently transition serialized attributes from YAML to JSON. In a recent test creating/reading serialized records JSON outperfoms YAML by a wide margin.

Serializing the entire contents of the ENV hash 50,000 times:

            user     system      total        real
yaml:  77.390000   9.220000  86.610000 (117.776747)
json:  52.870000   8.240000  61.110000 ( 89.297786)

Deserializing those same 50,000 records:

            user     system      total        real
yaml:  10.120000   0.380000  10.500000 ( 15.818386)
json:   2.840000   0.100000   2.940000 (  7.896888)

Installation

Add this line to your application's Gemfile:

gem 'serialize_yaml2json'

And then execute:

$ bundle

Or install it yourself as:

$ gem install serialize_yaml2json

Usage

Update your models to use this Coder.

class Widget < ActiveRecord::Base
  # serialize :data
  serialize :data, SerializeYAML2JSON::Coder
end

# NOTE: 'data' will now be a hash with indifferent access.
# This is because JSON doesn't understand symbols and stringifies
# all keys.  YAML could do either.  This is necessary to support
# existing access to the attributes.
