sidekiq-scheduler is an extension to Sidekiq that adds support for running scheduled.
Scheduled jobs are like cron jobs, recurring on a regular basis.
This README covers what most people need to know. If you're looking for details on individual methods, you might want to try the rdoc.
Add this to your Gemfile:
gem 'sidekiq-scheduler', '~> 1'
If you are using rails you are set
If you are not using rails create a file with this content:
and the execute:
sidekiq -r created_file_path.rb
Look at [Loading the schedule][https://github.com/moove-it/sidekiq-scheduler/tree/0.x#loading-the-schedule] for information on how to load your schedule.
You can add sidekiq-scheduler configuration options to sidekiq.yml config file. Available options are:
:schedule: <the schedule to be run> :dynamic: <if true the schedule can we modified in runtime>
Scheduled (or recurring) jobs are logically no different than a standard cron job. They are jobs that run based on a fixed schedule which is set at startup.
The schedule is a list of Sidekiq worker classes with arguments and a schedule frequency (in crontab syntax). The schedule is just a hash, but is most likely stored in a YAML like so:
CancelAbandonedOrders: cron: "*/5 * * * *" queue_documents_for_indexing: cron: "0 0 * * *" # you can use rufus-scheduler "every" syntax in place of cron if you prefer # every: 1hr # By default the job name (hash key) will be taken as worker class name. # If you want to have a different job name and class name, provide the 'class' option class: QueueDocuments queue: high args: description: "This job queues all content for indexing in solr" clear_leaderboards_contributors: cron: "30 6 * * 1" class: ClearLeaderboards queue: low args: contributors description: "This job resets the weekly leaderboard for contributions"
You can provide options to "every" or "cron" via Array:
clear_leaderboards_moderator: every: ["30s", :first_in => '120s'] class: CheckDaemon queue: daemons description: "This job will check Daemon every 30 seconds after 120 seconds after start"
NOTE: Six parameter cron's are also supported (as they supported by rufus-scheduler which powers the sidekiq-scheduler process). This allows you to schedule jobs per second (ie: "30 * * * * *" would fire a job every 30 seconds past the minute).
A big shout out to rufus-scheduler for handling the heavy lifting of the actual scheduling engine.
Let's assume your scheduled jobs are defined in a file called "config/scheduler.yml" under your Rails project, you could create a Rails initializer called "config/initializer/scheduler.rb" which would load the job definitions:
require 'sidekiq/scheduler' Sidekiq.schedule = YAML.load_file(File.expand_path("../../../config/scheduler.yml",__FILE__))
If you were running a non Rails project you should add code to load the workers classes before loading the schedule.
require 'sidekiq/scheduler' Dir[File.expand_path('../lib/workers/*.rb',__FILE__)].each do |file| load file; end Sidekiq.schedule = YAML.load_file(File.expand_path("../../../config/scheduler.yml",__FILE__))
You can also put your schedule information inside sidekiq.yml and load it with:
sidekiq -C ./config/sidekiq.yml
Note that if you use the cron syntax, this will be interpreted as in the server time zone
rather than the
config.time_zone specified in Rails.
You can explicitly specify the time zone that rufus-scheduler will use:
cron: "30 6 * * 1 Europe/Stockholm"
Also note that
config.time_zone in Rails allows for a shorthand (e.g. "Stockholm")
that rufus-scheduler does not accept. If you write code to set the scheduler time zone
config.time_zone value, make sure it's the right format, e.g. with:
A future version of sidekiq-scheduler may do this for you.
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.

Modified to work with the Sidekiq queueing library by Morton Jonuschat. Scheduling of recurring jobs has been added to v0.4.0, thanks to Adrian Gomez.
