> When global memstore reaches the low water mark, we pick the best flushable
> region and flush all column families for it. This is a suboptimal approach in
> the sense that it leads to an unnecessarily high file creation rate and IO
> amplification due to compactions. We should still try to honor the underlying
> FlushPolicy.
