Redis HGETALL command is used to get all the fields and values of the hash stored at the key. In the returned value, every field name is followed by its value, so the length of the reply is twice the size of the hash.
Return Value
Array reply, list of fields and their values stored in the hash, or an empty list when the key does not exist.
