    Description

      Currently we identify hole regions during MVCCIterator. One of the reasons for this was we set purgeHint during MVCCIterator, which can lead to compactFullMarshal.  We have a pageFlagEmpty for empty pages which we can leverage. I am filing this MB to improve the functionality to try identify hole regions without depending on GSI range scans. This should also benefit backstore.
