Review comment:
       but the stale data will always be present inside segment folder right? 
by chance assume if the segment file is corrupted or deleted, still carbon 
should pass the query, which it does by listing, in that case we will get the 
wrong data or query will always fail. I think we need to have some way to clean 
them, what you think @QiangCai @ajantha-bhat
