> [Analytics] Add support for vnodes
> ----------------------------------
>
> Key: CASSANDRA-20075
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20075
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Analytics Library
> Reporter: James Berragan
> Assignee: Andrew Johnson
> Priority: Normal
> Time Spent: 4h 50m
> Remaining Estimate: 0h
>
> 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.
