> Hi,
> To specify stream throughputs of a node more clearly, I would like to add the
> following new inbound parameters like existing outbound parameters in the
> cassandra.yaml.
> - stream_throughput_inbound_megabits_per_sec
> - inter_dc_stream_throughput_outbound_megabits_per_sec
> We use only the existing outbound parameters now, but it is difficult to
> control the total throughputs of a node. In our production network, some
> critical alerts occurs when a node exceed the specified total throughput
> which is the sum of the input and output throughputs.
> In our operation of Cassandra, the alerts occurs during the bootstrap or
> repair processing when a new node is added. In the worst case, we have to
> stop the operation of the exceed node.
> I have attached the patch under consideration. I would like to add a new
> limiter class, StreamInboundRateLimiter, and use the limiter class in
> StreamDeserializer class. I use Row::dataSize( ）to get the input throughput
> in StreamDeserializer::newPartition(), but I am not sure whether the
> dataSize() returns the correct data size.
> Can someone please tell me how to do it ?
