> IndexTool can avoid writing index rows if they are already consistent with 
> data-table. This will specially be useful when rebuilding index on DR-site 
> where indexes are replicated already, but rebuild might be needed for catchup.
> Likewise, during upgrades from old indexing scheme to new consistent indexing 
> scheme, if the index data columns are consistent already, IndexTool should 
> only rewrite the EmptyColumn to mark the row as verified instead of writing 
> the data columns too.
