> Key: CASSANDRA-3041
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3041
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.8.4
> Reporter: Nick Bailey
> Fix For: 0.8.6
>
> Attachments:
> 0001-Don-t-stream-to-replicas-that-already-have-the-data.patch, 3041-v2.txt

>
> When you decommission a node, it only streams data to the node that is just
> now gaining responsibility for the node's primary range.
> When you move a node it streams data to every node that is responsible for
> the node's primary range. This is way more than it needs to, and could be bad
> in multi-dc setups. We should absolutely use this bug as a chance/reason to
> better unify that code, since move should be doing the same thing decom does.
> This might be worth backporting to 0.8 as well.
