> Key: CASSANDRA-16274
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16274
> Project: Cassandra
> Issue Type: Improvement
> Components: Consistency/Repair
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Priority: Normal
> Fix For: 4.0-beta4
>
>
> The way stream tasks are calculated currently is quite inefficient, improve
> that.
> Also, we currently try to distribute the streaming nodes evenly, this creates
> many more sstables than necessary - instead we should try to stream
> everything from a single peer, this should reduce the number of sstables
> created on the out-of-sync node.
