--------------------------------------
Summary: Stream hints on decommission
Key: CASSANDRA-5128
URL: https://issues.apache.org/jira/browse/CASSANDRA-5128
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.2.1
Reporter: Jason Brown
Assignee: Jason Brown
Looks like decommissioning a node (nodetool decommission) will stream all the
non-system table data out to it's appropriate peers
(StorageService.unbootstrap()), but hints will disappear with the node. Let's
send those hints to another peer (preferably in the same rack, and hopefully at
least the same datacenter) them to be replayed.
The use case here is auto-scaling vnode clusters in ec2. When auto-scaling
down, I'd want to call decommission on the node to leave the ring (and be
terminated), and still have all of it's artifacts (data and hints) survive.
