-------------------------------
bq. This is mostly to improve high performance counters (HPC)....
Just reading them?
Or is it to speed increments?
> Get/Scan from MemStore only (Client API)

> 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.
