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: redis.rb
    path of file: ./repos/storyblok-ruby-client/lib/storyblok/cache
    
    the code of the file until where you have to start completion: module Storyblok
  module Cache
    class Redis
      DEFAULT_CONFIGURATION = {
        ttl: 60 * 60 * 24
      }.freeze

      attr_reader :redis

      def initializ
    
      def initialize(*args)
        options = args.last.is_a?(::Hash) ? args.pop : {}

        @redis = options.delete(:redis) || begin
          if defined?(::Redis)
            ::Redis.current
          else
            raise "Redis.current could not be found. Supply :redis option or make sure Redis.current is available."
          end
