Thanks a lot Michal & Ofir for your insights. To Ofir - I have not yet finalized my spark streaming code. it is still work in progress. Now we have Structured streaming available, so thought to re write it to gain maximum benefit in future. As of now, there are no specific functional or performance issues Nor I have to leverage any new API. This is just considering future aspects.
