UniqueJobs

Provides uniqueness for jobs.

Usage

Example worker:

class UniqueWorker
  include Sidekiq::Worker

  sidekiq_options({
    # Should be set to true (enables uniqueness for async jobs)
    # or :all (enables uniqueness for both async and scheduled jobs)
    unique: :all,

    # Unique expiration (optional, default is 30 minutes)
    # For scheduled jobs calculates automatically based on schedule time and expiration period
    expiration: 24 * 60 * 60
  })

  def perform
    # Your code goes here
  end
end

Custom lock key and manual expiration:

class UniqueWorker
  include Sidekiq::Worker

  sidekiq_options({
    unique: :all,
    expiration: 24 * 60 * 60,
    
    # Set this to true when you need to handle locks manually.
    # You'll be able to handle unique expiration inside your worker.
    # Please see example below.
    manual: true
  })
  
  # Implement your own lock string
  def self.lock(id)
    "locks:unique:#{id}"
  end
  
  # Implement method to handle lock removing manually
  def self.unlock!(id)
  	lock = self.lock(id)
    Sidekiq.redis { |conn| conn.del(lock) }
  end

  def perform(id)
    # Your code goes here
    # You are able to re-schedule job from perform method,
    # Just remove lock manually before performing job again.
    sleep 5
    
    # Re-schedule!
    self.class.unlock!(id)
    self.class.perform_async(id)
  end
end
