Andrew Purtell commented on HBASE-11054:
----------------------------------------
On the design of this particular hook.... Usually with hooks we take in as
parameter an existing object and return the same type, which could be the input
object with possibly modified state, or a new object allocated within the hook
using the input object as a template. The hook here can only blindly create a
DeleteTracker and that's not as flexible as if instead there is an option to
take the tracker allocated by core and mix in state.
> 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.
