Marshalling is transforming the object into a byte stream for storage or transmission, in ruby when we push a object to
Sidekiq to fetch and process we use marshalling.
2.7.2 :004 > marshaled = Marshal.dump('this is an object') => "\x04\bI\"\x16this is an object\x06:\x06ET"
Now when the
Sidekiq starts processing the job then the data is fetched from the
redis in byte stream and converted back to ruby object.
2.7.2 :006 > Marshal.load(marshaled) => "this is an object"
