> 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.).
