stack commented on HBASE-4507:
------------------------------
Though... (bicycle ride between above comment and this)... its kinda lame our
versioning can't be used detecting a cell has been changed. Our versioning has
the above described hole where an update that doesn't change the value goes
undetected (without this hack applied). This is kinda lame. Let me open an
issue to address this. This patch did some clog dancing to ensure each edit
had its own 'version' timestamp but has limitations (only one edit per ms max).
Its like we need a edit sequence id per millisecond. Let me open a new issue
to address this shortfall properly.
