             Summary: [Analytics] Add support for vnodes
                 Key: CASSANDRA-20075
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-20075
             Project: Cassandra
          Issue Type: Improvement
          Components: Analytics Library
            Reporter: James Berragan


Analytics currently assumes 1 token per node, but most people in the community 
use vnodes by default. We should add support for vnodes, at the most basic 
level we can improve to issue a Spark task per vnode range. After that 
optimizations can be added to more intelligently merge contiguous ranges, or 
sort tasks to avoid the Spark JVM connecting to the entire cluster.
