Delayed Deltas for Thinking Sphinx with Sidekiq

This code was heavily based on Aaron Gibralter's ts-resque-delta, and was initially adapted for Sidekiq by Danny Hawkins. This release is maintained by Pat Allan.

This version of ts-sidekiq-delta works only with Thinking Sphinx v3 or newer. v1/v2 releases are not supported, and almost certainly will never be. It does work with the Flying Sphinx service, provided you're using 1.0.0 or newer of the flying-sphinx gem.

Get it into your Gemfile - and don't forget the version constraint!

gem 'ts-sidekiq-delta', '~> 0.4.0'

If you're using Thinking Sphinx v3.0.x, you'll need to jump back to the 0.1.0 release of this gem.

In your index definitions, you'll want to include the delta setting as an initial option:

ThinkingSphinx::Index.define(:article,
  :with  => :active_record,
  :delta => ThinkingSphinx::Deltas::SidekiqDelta
) do
  # fields and attributes and such
end

If you've never used delta indexes before, you'll want to add the boolean column named :delta to each model's table and a corresponding database index:

def change
  add_column :articles, :delta, :boolean, :default => true, :null => false
  add_index  :articles, :delta
end

From here on in, just use Thinking Sphinx and Sidekiq as you normally would, and you'll find your Sphinx indices are updated quite promptly by Sidekiq.

Make sure you have a sidekiq worker monitoring the ts_delta queue.
