--------------------------------------
Labels: client-impacting (was: )
> 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
> Priority: Major
> Labels: client-impacting
>
> 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.
