tasque

ActiveRecord based task queue. Task processing queue with states, history and priorities. Works with your favorite database.

Installation

Add this line to your application's Gemfile:

gem 'tasque'

And then execute:

$ bundle

Or install it manually:

$ gem install tasque

Then you need to generate initializer and migration:

$ rails g tasque:install

Don't forget to run migrations:

$ rake db:migrate

Usage

Create a simple task:

Tasque::Task.create! task: 'test', params: { text: 'This is the test!' }

Or a task with priority:

Tasque::Task.create! task: 'test', priority: 9000, params: { text: 'I will be processed first!!!' }

Or add a tag to find this task easily:

Tasque::Task.create! task: 'test', tag: 'user_123', params: { text: 'This task is property of User #123!' }

Now to process the task:

# create task processor
processor = Tasque::Processor.new

# register a handler for test tasks
processor.add_handler('test') do |task|
  puts "Got task ##{task.id}. Task says: '#{task.params['text']}'"
  task.complete!
  { log: 'got task, printed text' } # returning task result
end

# start processor and wait
processor.start

Using with Insque

Tasque can send task and worker state updates via Insque.

To enable this featute uncomment following lines in your tasque initializer:

# Send task state updates and progress notifications via Insque
config.notify = true

# Send worker heartbeat via Insque
config.heartbeat = true
config.heartbeat_interval = 10 # seconds

# Use RedisMutex instead of database transaction 
config.use_mutex = true
