Yes Shahid, you are right. During Update scenario there is a chance of
creating new data within the same segment. And it will lead to wrong data if
the schema is different. It is not same case for delete as we don't have any
schema for it.

I feel we always better create a new segment even for update if any new data
is added instead of updating the same segment.
