Delayed Deltas for Thinking Sphinx (with Resque)
This code is HEAVILY borrowed from ts-delayed-delta.
This gem depends on the following gems:
Currently, you'll need Thinking Sphinx v1.5.0 (for Rails 2), v2.1.0
(for Rails 3), or - ideally - v3.0.3 or newer (for Rails 3.1 onwards). If you're
on a version of Thinking Sphinx that's too old, you better go upgrade - but
ts-resque-delta to your
Gemfile file with the rest of your
gem 'ts-resque-delta', '~> 2.0.0'
Add the delta property to index definition. If you're using Thinking Sphinx v3, then it'll look something like this:
ThinkingSphinx::Index.define(:article, :with => :active_record, :delta => ThinkingSphinx::Deltas::ResqueDelta ) do # fields and attributes and so on... end
But if you're still using v1.5 or v2.1, you'll want the following:
define_index do # fields and attributes and so on... set_property :delta => ThinkingSphinx::Deltas::ResqueDelta end
If you've never used delta indexes before, you'll need to add the boolean
:delta to each table for indexed models. A database index for
that column is also recommended.
def change add_column :articles, :delta, :boolean, :default => true, :null => false add_index :articles, :delta end
Once you've got it all set up, all you need to do is make sure that the Resque
worker is running. You can do this by specifying the
ts_delta queue when
QUEUE=ts_delta,other_queues rake resque:work
