DelayedJobEs

Delayed Job Backend adapter for ElasticSearch.

The gem uses the 'elasticsearch-transport' and 'elasticsearch-api' as dependencies.

It has no other dependencies, and should be easy to integrate into any ruby based project that uses elasticsearch in any form.

Add this line to your application's Gemfile:

gem 'delayed_job_es'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install delayed_job_es

Create a Job Class in the app/jobs folder :

  	class BackgroundJob < ActiveJob::Base
  
  		queue_as :default

  		## Specify the queue adapter as delayed_job_es
  		self.queue_adapter = :delayed_job

  		self.logger = Logger.new(nil) if Rails.env.test? 

	  	rescue_from(StandardError) do |exception|
	  		puts exception.message
	   		puts exception.backtrace.join("\n")
	  	end
  
  		def perform(args)
  			## process job here.
  		end

  	end

Create required ES Indexes:

# in the rails console, (you only need to do this once)
DelayedJob::Backend::Es::Job.create_indices

Open a terminal window, navigate to your project and run :

$ bundle exec rake jobs:work

This will run a job daemon(standard DelayedJob).

To queue a job, from anywhere using the job class above run (you can try this in the rails console, in another window):

BackgroundJob.perform_later({"hello" => "world"})

If you look in the jobs daemon window, you will see the job getting processed.
