Nicolas Liochon commented on HBASE-11054:
-----------------------------------------
I wonder is there is a good reason to extend the RegionObserver directly? In
this case it could become private?
Now that I think about it again, I think that we should always add a @since
annotation as well (not for this change, but for the next ones). This way the
developer knows that he is using an API not available in a previous dot release
(we can easily imagine that multiple distros may have different underlying
hbase dot version).

> 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.
