Alexey Zotov commented on CASSANDRA-4769:
-----------------------------------------
Yes, it's the simplest way. But what's about the following use case:
There are N remote data centers. Each data center sends hints to restored node.
So that node will receive throttle_in_kb*N*Nrf of data per second. (Nrf -
replication factor in Nth data center)
You could reduce throttle threshold, but in case of local node very small
threshold is not a very good idea.
I think that mechanism shoud be more configurable.
> Prevent parallel hint delivery to the node

> 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.
