> Current counter type is not sortable by values, AFAIK. Here's a related question :

> This feature can be very handy for 'top N' type query use cases like sorting user points and finding top users in a reputation system.
> Of course, support in CQL 3 is trivial.
> IMHO, from implementation point of view, this looks unnatural to C* since C* sorts column names not the values.Maybe a composite column solution like (counter,char) is more proper but I can't imagine a way to make this work right now, it doesn't make sense to me. On the other hand, it would be very useful for us, the users.
