Type: New Feature
Fix Version/s: None
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.
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 ?
