             Summary: Allow Token-Aware drivers for range scans
                 Key: CASSANDRA-14311
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14311
             Project: Cassandra
          Issue Type: Improvement
          Components: Coordination
            Reporter: Avi Kivity

Currently, range scans are not token aware. This means that an extra hop is 
needed for most requests. Since range scans are usually data intensive, this 
causes significant extra traffic.


Token awareness could be enabled by having the coordinator return the token for 
the next (still unread) row in the response, so the driver can select a next 
coordinator that owns this row.
