Re: Coordinator node

We are using haproxy in TCP mode for round-robin with great succes.
It's bit unorthodox but has same real added values like logging.

Here is the relavant config for haproxy:

#####

global
    log 127.0.0.1 local0
    log 127.0.0.1 local1 notice
    maxconn 4096
    user haproxy
    group haproxy
    daemon

defaults
    log global
    mode tcp
    maxconn 2000
    contimeout 5000
    clitimeout 50000
    srvtimeout 50000

listen cassandra 0.0.0.0:9160
    balance roundrobin
    server db1 ec2-XXX.compute-1.amazonaws.com:9160 check observe layer4
    server db2 ec2-YYY.compute-1.amazonaws.com:9160 check observe layer4
    server db3 ec2-ZZZ.compute-1.amazonaws.com:9160 check observe layer4
