> Improve Kafka core code :
> Remove redundant val modifier for case class constructor
> Use flatMap instead of map and flatten
> Use isEmpty, NonEmpty, isDefined as appropriate
> Use head, keys and keySet where appropriate
> Use contains, diff and find where appropriate
> toString has no parameters, no side effect hence without () use consistently
> Remove unnecessary return and semi colons, parentheses
