> 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.
