> The connection router consistent hash modulo key transformer does not work
> well if the hash produced a negative value.
> It makes matching more difficult to configure b/c both -1 and 1 need to be
> matched for a broker ordinal 1.
>
> it would be better if the modulo was confined to positive numbers, rather
> than the signed remainder.
