Since “worker” is a nebulous term, we’ve deprecated the use of this class name. Is “worker” a process, a type of job, a thread? Undefined! WorkSet better describes the data.

Worker =

Sidekiq::Job is a new alias for Sidekiq::Worker as of Sidekiq 6.3.0. Use ‘include Sidekiq::Job` rather than `include Sidekiq::Worker`.

The term “worker” is too generic and overly confusing, used in several different contexts meaning different things. Many people call a Sidekiq process a “worker”. Some people call the thread that executes jobs a “worker”. This change brings Sidekiq closer to ActiveJob where your job classes extend ApplicationJob.

.configure_client {|default_configuration| ... } ⇒ Object

Yields:

# File 'lib/sidekiq.rb', line 136

def self.configure_client
  yield default_configuration unless server?
end

.configure_embed {|cfg| ... } ⇒ Object

Creates a Sidekiq::Config instance that is more tuned for embedding within an arbitrary Ruby process. Notably it reduces concurrency by default so there is less contention for CPU time with other threads.

instance = Sidekiq.configure_embed do |config|
  config.queues = %w[critical default low]
end
instance.run
sleep 10
instance.stop

NB: it is really easy to overload a Ruby process with threads due to the GIL. I do not recommend setting concurrency higher than 2-3.

NB: Sidekiq only supports one instance in memory. You will get undefined behavior if you try to embed Sidekiq twice in the same process.

Yields:

  • (cfg)
