JS> The results are aggregated AFAIK. If you do a key range and keys are on 3 nodes it'll return a cohesive list. It's much more tricky to get a list of ALL of the keys across the cluster. We've found that you need to do many key ranges to enumerate over all of the keys in the cluster. JS> It's possible, just not wrapped in a simple function. Is this worth a JIRA feature request? Or is it something Cassandra will never support fully? From the user's perspective it's very useful. Thanks Ted
