------------------------------------------
Resolution: Duplicate
> rethink stream throttling logic
> -------------------------------
>
> Key: CASSANDRA-11351
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11351
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Brandon Williams
>
> Currently, we throttle steaming from the outbound side, because throttling
> from the inbound side is thought as not doable. This creates a problem
> because the total stream throughput is based on the number of nodes involved,
> so based on the operation to be performed it can vary. This creates
> operational overhead, as the throttle has to be constantly adjusted.
> I propose we flip this logic on its head, and instead limit the total inbound
> throughput. How? It's simple: we ask. Given a total inbound throughput of
> 200Mb, if a node is going to stream from 10 nodes, it would simply tell the
> source nodes to only stream at 20Mb/s when asking for the stream, thereby
> never going over the 200Mb inbound limit.
