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: realtime.rb
    path of file: ./repos/sidekiq-statistic/lib/sidekiq/statistic/statistic
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Sidekiq
  module Statistic
    class Realtime < Base
      
    
      def realtime_hash
        Sidekiq.redis do |conn|
          redis_hash = {}
          conn
            .hgetall("#{Metrics::Store::REDIS_HASH}:realtime:#{Time.now.sec - 1}")
            .each do |keys, value|
              *keys, last = keys.split(KEY_SEPARATOR)
              keys.inject(redis_hash, &key_or_empty_hash)[last] = value.to_i
            end

          redis_hash
        end
      end
