> Dealing with hints after a topology change

> Key: CASSANDRA-5902
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5902
> Project: Cassandra
> Issue Type: Bug
> Reporter: Jonathan Ellis
> Assignee: Ala' Alkhaldi
> Priority: Minor
>
> Hints are stored and delivered by destination node id. This allows them to
> survive IP changes in the target, while making "scan all the hints for a
> given destination" an efficient operation. However, we do not detect and
> handle new node assuming responsibility for the hinted row via bootstrap
> before it can be delivered.
> I think we have to take a performance hit in this case -- we need to deliver
> such a hint to *all* replicas, since we don't know which is the "new" one.
> This happens infrequently enough, however -- requiring first the target node
> to be down to create the hint, then the hint owner to be down long enough for
> the target to both recover and stream to a new node -- that this should be
> okay.
