Background jobs using PostgreSQL's LISTEN/NOTIFY
Add this line to your application's Gemfile:
gem 'pg_queue'
And then execute:
$ bundle
Or install it yourself as:
$ gem install pg_queue
Now you need to create the table where jobs will be stored:
$ rake environment pg_queue:create_table
Run rake -T pg_queue for more tasks
Create an initializer with the configuration
PgQueue.connection = ActiveRecord::Base.connection.raw_connection
PgQueue.logger = Rails.logger
PgQueue.interval = 3 # the number of seconds you want the worker wait after process a job
Add this line in the Rakefile
require "pg_queue/tasks"
And then start the worker running
rake environment pg_queue:work
That's it! You're now able to enqueue your jobs. To do that, just call
PgQueue.enqueue(MyQueueClass, "string", 1, false) # parameters will be JSON encoded
