Vijay updated CASSANDRA-6596:
-----------------------------
Attachment: 0001-CASSANDRA-6596.patch
Attached patch introduces inter_dc_stream_throughput_outbound_megabits_per_sec
which is a subset of stream_throughput_outbound_megabits_per_sec.
Currently the node throttles all the traffic which it streams (this doesn't
change after this patch). In addition, this patch adds additional throttle
across the DC's.
One more thing: There might be a bug (in trunk) where the throttle is applied
on bytes instead of bits... Since its not related to this ticket, i have not
changed it.
{code}
int toTransfer = (int) Math.min(transferBuffer.length, length -
bytesTransferred);
int minReadable = (int) Math.min(transferBuffer.length, reader.length()
- reader.getFilePointer());
reader.readFully(transferBuffer, 0, minReadable);
if (validator != null)
validator.validate(transferBuffer, 0, minReadable);
limiter.acquire(toTransfer);
{code}

> Currently the outgoing stream throughput setting doesn't differentiate
> between when it goes to another node in the same DC and when it goes to
> another DC across a potentially bandwidth limited link. It would be nice to
> have that split out so that it could be tuned for each type of link.
