Simple Sidekiq Batch Job implementation.


Add this line to your application's Gemfile:

gem 'sidekiq-batch'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sidekiq-batch


Sidekiq Batch is MOSTLY a drop-in replacement for the API from Sidekiq PRO. See for usage.


Consider the following workflow:

  • Batch Z created
  • Worker A queued in batch Z
  • Worker A starts Worker B in batch Z
  • Worker B completes before worker A does
  • Worker A completes

In the standard configuration, the on(:success) and on(:complete) callbacks will be triggered when Worker B completes. This configuration is the default, simply for legacy reasons. This gem adds the following option to the sidekiq.yml options:

:batch_push_interval: 0

When this value is absent (aka legacy), Worker A will only push the increment of batch jobs (aka Worker B) when it completes

When this value is set to 0, Worker A will increment the count as soon as WorkerB.perform_async is called

When this value is a positive number, Worker A will wait a maximum of value-seconds before pushing the increment to redis, or until it's done, whichever comes first.

This comes into play if Worker A is queueing thousands of WorkerB jobs, or has some other reason for WorkerB to complete beforehand.

If you are queueing many WorkerB jobs, it is recommended to set this value to something like 3 to avoid thousands of calls to redis, and call WorkerB like so:

WorkerB.perform_in(4.seconds, some, args)

this will ensure that the batch callback does not get triggered until WorkerA and the last WorkerB job complete.

If WorkerA is just slow for whatever reason, setting to 0 will update the batch status immediately so that the callbacks don't fire.
