Brandon Williams updated CASSANDRA-4369:
----------------------------------------
Labels: ponies (was: )
> Sortable counter type for 'top N' type query use cases
> ------------------------------------------------------

> Key: CASSANDRA-4369
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4369
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Ahmet AKYOL

> Current counter type is not sortable by values, AFAIK. Here's a related
> question :
> http://stackoverflow.com/questions/8428364/how-to-get-sorted-counters-from-cassandra
> 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.
