>
> A metric to identify number of reads that were served from memstore (atleast
> if the gets can be accounted for) then it gives a value addition to know if
> among the reads how much was targeted at the most recent data.
> Currently the existing metric framework at region level should be enough but
> we can also add a metric per store level. That will be more granular.
> We can also expose this via HbTop.
