Anoop Sam John commented on HBASE-11054:
----------------------------------------
We added a new cp method in RegionObserver. If a user having a cp impl,
directly implementing RegionObserver (not extending BaseRegionObserver) the
addition of new method will break compatibility.
> Create new hook in StoreScanner to help user creating his own delete tracker

> In case of Visibility labels, to support deletes we need to consider the
> visibility expression per version inorder to identify the matching visibility
> expression.
> Tracking the visibility tags along with the delete tracker would make things
> easier rather than handling during scans/compactions.
