sidekiq_batch_callbacks

📦 High‑Throughput Batch Processing with Sidekiq::Batch​

When you need to launch hundreds or thousands of jobs as a unit and track completion, Sidekiq Pro’s Batch API is indispensable. You can attach callbacks for success, death, or custom events to execute cleanup or next‐phase tasks once the batch completes.

batch = Sidekiq::Batch.new
batch.description = "Bulk user data refresh"
batch.on(:success, 'BatchCallback#on_success', { report_id: 42 })

batch.jobs do
  User.find_in_batches(batch_size: 1000) do |group|
    RefreshUserJob.perform_async(group.map(&:id))
  end
end

# app/workers/batch_callback.rb
class BatchCallback
  def self.on_success(status, options)
    ReportMailer.batch_finished(options[:report_id], status.total).deliver_now
  end
end
