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. -Wei
