> After discussing with Michael, the issue was that if you have a region size
> of for example 256M and you add a 1G value into a column then that region
> cannot split and a cluster can become lopsided. It also means that you have a
> really large block and the memstore would need to handle the 1G data. I
> proposed to add a configurable upper boundary check that is throwing an
> exception on the client side if the user tries to add a value larger than
> that limit. Ideally it would be set to the maximum region size or less.
