>
> In SSTableSimpleUnsortedWriter, when dealing with rows having a lot of
> columns, if we call newRow several times (to flush data as soon as possible),
> the time taken by the newRow() call is increasing non linearly. This is
> because when newRow is called, we merge the size increasing existing CF with
> the new one.
