> For incrementColumnValue operations, it is possible to check MemStore for the 
> column being incremented without sacrificing correctness.  If the column is 
> not found in MemStore, we would then have to do a normal Get that 
> opens/checks all StoreFiles for the given Store.
> In practice, this makes increment operations significantly faster for 
> recently/frequently incremented columns.
