Brandon Williams commented on CASSANDRA-4769:
---------------------------------------------
I think phrasing this in terms of DCs is overcomplicating things, it's
sufficient to imagine one large ring and realize that a recovering node is
going to received throttle_in_kb*N since all other nodes are going to replay
hints to it. There's no way to prevent this though, the closest thing we had
in the past was a random sleep to stagger the beginning of the replay. Tuning
the throttle appropriately is the best option now.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-4769
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1.2
> Reporter: Alexey Zotov
>
> It's actual only in case of the using a big enough cluster. After node's
> failure other nodes try to send hints to the restored node. So theoretically
> it can affect performance of restored node.
> I suggest to create some mechanism for synchronization of hints delivery
> processes to restored node.
> Could you please explain how it can be implemented.
