Brandon Williams commented on CASSANDRA-8132:
---------------------------------------------
I don't understand. When you replace a node it has the same host id so the
existing hints are replayed from wherever they exist. Where are you proposing
we stream them and to what end?
> Save or stream hints to a safe place in node replacement

> Key: CASSANDRA-8132
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8132
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Minh Do

> Fix For: 2.1.1

>
> Often, we need to replace a node with a new instance in the cloud environment
> where we have all nodes are still alive. To be safe without losing data, we
> usually make sure all hints are gone before we do this operation.
> Replacement means we just want to shutdown C* process on a node and bring up
> another instance to take over that node's token.
> However, if a node has a lot of stored hints, HintedHandofManager seems very
> slow to play the hints. In our case, we tried to replace a node and had to
> wait for several days.
> Since this is not a decommission, I am proposing that we have the same
> hints-streaming mechanism as in the decommission code. Furthermore, there
> needs to be a cmd for NodeTool to trigger this.
