   @rakeshadr 
   I think with this approach, a cluster upgraded from an older version and if someone want to try a new layout version format, they cannot use it. IMHO, I think we should support older buckets read/write, and provide the capability to support users to try out the new format on the newly created buckets.
   
   One Idea here is to persist format layout in bucket metadata and use that. And also iterate the buckets(Even now we iterate buckets during startup) and set layout version of the buckets to older format layout during startup if the format is not set. (I think this approach has been discussed during initial meetings)
