hi; we are upgrading our cluster from apache-cassandra 2.0.14 to 2.0.17. We have been facing SYN flooding issue (port 9042) in our current version of Cassandra at times. We are hoping to tackle the SYN flooding issues with the following attributes in the YAML file for 2.0.17
native_transport_max_concurrent_connections native_transport_max_concurrent_connections_per_ip Are there any observed limitations for the above mentioned attributes. During the peak hours each node serves around 1500 connections. Please suggest optimal values for the mentioned attributes. thanks
