You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: delayed_sidekiq.rb
    path of file: ./repos/chewy/lib/chewy/strategy
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Chewy
  class Strategy
    class DelayedSidekiq < Sidekiq
      require_relative 'delayed_sidekiq/scheduler'

      # cleanup the 
    
      def self.clear_timechunks!
        ::Sidekiq.redis do |redis|
          timechunk_sets = redis.smembers(Chewy::Strategy::DelayedSidekiq::Scheduler::ALL_SETS_KEY)
          break if timechunk_sets.empty?

          redis.pipelined do |pipeline|
            timechunk_sets.each { |set| pipeline.del(set) }
          end
        end
      end
