Subject Does setstreamthroughput also throttle the network traffic caused by nodetool repair?
Date Fri, 25 Jan 2013 01:31:31 GMT
In the yaml, it has the following setting

# Throttles all outbound streaming file transfers on this node to the
# given total throughput in Mbps. This is necessary because Cassandra does
# mostly sequential IO when streaming data during bootstrap or repair, which
# can lead to saturating the network connection and degrading rpc performance.
# When unset, the default is 400 Mbps or 50 MB/s.
# stream_throughput_outbound_megabits_per_sec: 400

Is this the same value as if I call

Nodetool setstreamthroughput 

Should I call it to all the nodes on the cluster? Will that throttle the network traffic
caused by nodetool repair?

Thanks.
