We will have to override this method in Get, Scan, Append and Increment
(wherever we want the feature) and return those types rather than
OperationWithAttributes. Also Put, Delete etc also will have this method
available. Do we need to throw Exception when some one calls this on Put,
Delete etc?

OK. Good point.

> This is short-circuit read for get/scan when recent data (version) of a cell
> can be found only in MemStore (with very high probability).
> Good examples are: Atomic counters and appends. This feature will allow to
> bypass completely store file scanners and improve performance and latency.
