You mean duplicate records on the consumer side? Duplicates are
possible if there are consumer failures and a another consumer
instance resumes from an earlier offset. It is also possible if there
are producer retries due to exceptions while producing. Do you see any
of these errors in your logs? Besides these scenarios though, you
shouldn't be seeing duplicates.
