@here I have noticed that while transferring data from mongodb to elastic search i am facing an error like from _id(mongo) to _id(elastic search) error parsing. So what possible solution should be for that issue??? And also i think this issue will be for all NoSQL sources and destinations.

Can you share the full error? Sometimes this comes up because of reserved keywords being used in the wrong place

Yes you are correct, reserved keyword used, _id(mongo), and have to use for identification. Please find the below error.
