dhruba borthakur commented on HBASE-2376:
-----------------------------------------

Awesome. This will be really helpful to mitigate any kind of application 
logical bugs where the app mistakenly removes a bunch of records from Hbase, 
then the user/admin realises his/her mistake, and wants to refetch those 
records from a previous point in time.

> Add special SnapshotScanner which presents view of all data at some time in 
> the past

> In order to support a particular kind of database "snapshot" feature which 
> doesn't require copying data, we came up with the idea for a special 
> SnapshotScanner that would present a view of your data at some point in the 
> past.  The primary use case for this would be to be able to recover 
> particular data/rows (but not all data, like a global rollback) should they 
> have somehow been messed up (application fault, application bug, user error, 
> etc.).
