      Description

      Writing pairs of timestamps for key/value pairs will potentially grow data sizes (it's at least one byte per timestamp, and likely two or more).

      Investigate adding a cell bit that flags theĀ "WT_TS_NONE - WT_TS_MAX" pair, that is, the timestamp pair that indicates global stability.

      It's not known if this is a possible change, we may investigate it and decide it's not possible.
